It sounds like a straightforward enough story: a soldier who had his legs blown off in the Vietnam War goes on to have a meaningful career making artificial limbs.
This is what happened to Tim Woodville, but it wasn't that simple. "I never thought, I'm an amputee, so I might as well go into prosthetics."
The first thing he had to do was survive the night in February 1971 when he lost his legs. "I laid on top of a charge that went off. It was night, so I didn't see it. It took my left leg off right then. At the same time, I had a hand grenade thrown at me. It went off. I don't know if it or the charge took off my right leg or even if it was gone right away." Woodville figures that being right on top of the charge helped keep him alive. "If I'd been just 3 feet away I would have been killed."
He said the scenes in John Wayne war movies about injured soldiers falling asleep and never waking up again seem to be accurate. "Your mind stays 'stop,' but your body says 'keep going.' My job that night was to stay alive. But you felt like you could just close your eyes, go to sleep and slip away."
The next thing he had to do was figure out what to do with the rest of his life. "I was going to make the military my career," but the loss of his legs forced him to change his plans.
When he returned to civilian life, there was a long adjustment period. "Obviously, my legs were gone. I was proud of what I had done in Vietnam, but there was no way I could say that at the time and be accepted by my peers."
He said he spent the next few years as "a semi-hermit. I didn't want to socialize with a lot of people." But after he decided to go to college, "I discovered that I could immerse myself in my studies."
At that time, he was not studying prosthetics. He earned a degree in biological sciences from UC Davis, got a teaching credential and taught science for a couple of years in Elk Grove. He then entered a master's degree program in biological sciences at Chico State University. He went into that field because he wanted to become a researcher, but decided against it when he discovered it could be a cutthroat profession.
During this time, he met his wife. "She's been my rock forever. I can't express how much she means to me."
About 20 years ago, he started having anxiety symptoms. "I went to the VA. They told me I had post-traumatic stress syndrome. At first I didn't believe them. I felt I had to suck it up, be a man." But he said over time he came to understand that being in a war is stressful, and you can't always acknowledge it at the time it is happening.
For a while he stayed at home and took care of his two sons while his wife went to school to become a cosmetologist. "I started going a little stir-crazy." That's when he decided to become a technician at a prosthetics business in Redding where he had gone to have his legs worked on. He liked the job so much that he went to UCLA to become a certified prosthetist.
He opened his Chico business, Tim Woodville's Orthotics and Prosthetics, about 15 years ago. What convinced him that this could be his life's work was that it allowed him to work with people — his clients — and his hands. He builds artificial limbs and orthotics braces in a lab at the back of his business. "One of the biggest rewards for me is seeing how clients, their spouses and their offspring realize how life can go on after amputation. I enjoy helping people get back to what they were doing before they lost a limb."
Woodville said he has a few regrets about having lost his legs. "I wish I could have played football with my boys when they were growing up. I like to walk on the beach with my wife. I can do it, but it's hard. I wish I could compete in a triathlon. I can swim and ride a bike, but I can't run."
Despite having lost his legs in the Vietnam War, Woodville still supports the military. "It gave me a sense of accomplishment, a sense of belonging to something bigger than myself. It's an honorable profession. And it's physical. I liked that part of it."

Walking made easier

Keith Richmond’s souvenir from a motorcycle crash about 14 years ago is the prosthetic right leg that replaced the one that had to be amputated.
Now the Lynchburg man hopes to change to a leg with a microprocessor knee - a technology that will let him walk on uneven surfaces and more naturally navigate stairs and ramps.
And that means hunting and fishing again.
“I had to quit all those activities,” said Richmond, 51, after the motorcycle accident, which caused the loss of his right leg and injuries to the other, as well as damage to his back.
He tried out the $30,000 Otto Bock C-Leg in Lynchburg this week.
“I like it,” said Richmond. “It’s going to take getting used to.”
Richmond and Wilbert Green of Ruther Glenn near Fredericksburg each got to use the C-Leg Wednesday at Excel Orthotics and Prosthetics on Langhorne Road. The C-Legs were brought to Lynchburg by manufacturer Otto Bock’s traveling team.
The two clients seemed intrigued and pleased in the results they were getting from the hydraulic technology controlled by a microprocessor.
Fifty times a second the hydraulics are fine-tuned so that the knee can react to subtle changes encountered by the attached foot.
It feels different, too.
“It has some resistance I’m not accustomed to on my other leg,” said Richmond, as he learned to adapt to the new mechanism’s style.
“The knee knows when to bend,” Douglas Walters explained in an interview. Walters is an orthotist and owner of the Roanoke-based Excel.
People have to learn to trust the knee - to step forward and have the knee move forward, lift up and extend.
“It kind of walks for you a little bit,” said Walters.
“Because the motion of walking is more normal, it’s also less wearing on the natural leg,” said Walters.
Currently, two or three companies manufacture microprocessor-control systems, said Joe McTernan of the Alexandria-based American Orthotic and Prosthetic Association, a nonprofit trade association.
McTernan, in a telephone interview, said the essential design of a hydraulic knee is a cylinder filled with fluid. A piston in the cylinder mimics the natural movement of the knee joint. The tension can be adjusted to allow the leg to swing with “more or less resistance.”
The microprocessor feature, said McTernan, makes thousands of readings, “and based on the readings, adjusts the fluid in the cylinder and automatically changes the rate at which the knee swings.”
The feedback is based on the person’s walking pattern, “so every time the patient swings the leg forward it is swinging at the most appropriate rate for the conditions at that moment in time.”
The technology is becoming more widely available, he said, and more insurance companies are willing to consider it an advancement in technology “as opposed to experimental technology.”
Fitting the devices takes extra training because the knee must be programmed using a computer, he said. Prescriptions for the legs come from the physician.
He noted that the average fluid-based prosthetic knee costs around $2,700. “The microprocessor is significantly more expensive,” he said.
McTernan doesn’t see microprocessor legs becoming the norm in the near future, however. The legs provide more stability, which is important for patients who fall a lot, he said.
Not everyone needs microprocessor technology. A person with an above-the-knee amputation that only transfers from the bed to a wheelchair doesn’t need it.
“We try to provide the patient what’s needed for his use level,” said Walters of Excel.
Keith Richmond is an active person.
Amy Richmond said that because her husband’s present prosthetic leg needs so much effort by his good leg in walking and standing, “he’s wearing that knee out,” she said. “This is going to save his left leg.”
The couple recently purchased a farm in Kentucky, where the new way of walking on uneven grounds - and hunting game - could be a great help.
On Wednesday, Wilbert Green of Ruther Glenn also seemed truly pleased with his trial run with the C-Leg.
The Vietnam-era veteran didn’t expect to get the chance. But, he’d done so well since last June after his amputation due to diabetes that his therapist suggested he consider a computerized leg.
“I’m like, ‘Yeah, right,’” said Green. “I don’t think the VA is going to give me a $30,000 leg.”
However, through some private funding, with Veteran’s Affairs supplementing a little, it looks like it might happen.
“I’m excited about it,” said Green, who tried out the leg in walking, sitting and stair situations. “With the old leg, I’d have to drag it.”
Although it’s less than a year since he’s used prosthesis, he’ll still have to re-learn his old way of walking.
The C-Leg can return some of that natural grace.
“With this, it’s designed not to think about it, just to walk,” said Green.
His wife Gwen said that his ability to walk so much earlier than expected after his surgery is because “he’s a very determined person.”
“He ran track for many years. That has a lot to do with that type of mind-set,” she said.
And she said, “It’s all about his faith in God, and what he believes God has in store for him.”
Jeff Honma, a certified prosthetist/orthotist, is based in Los Angeles and works with the Otto Bock company. He was doing the computer programming for the legs being tried out in Lynchburg.
The hardest part most people have in using the C-Leg, said Honma, is “not thinking about how the knee works, and not thinking about the walking.”
Then, after awhile, “Timing becomes second nature.”
Scott Moltzan, also with Otto Bock, has an above-the-knee amputation and has worn the C-Leg for seven years.
He doesn’t have to look down at the ground anymore, said Moltzan, as he walked down the sloping grassy area outside the Langhorne road office, head up. “I can look right at you.”

Vietnam landmine victims to get more Aussie aid
Peace Journalism Posted April 13th, 2007 by Tarique International
Melbourne, April 13 (NNN-BERNAMA) Landmine victims in Vietnam will receive extra funding from the Australian Government for their physical rehabilitation.
The A$1.5 million contribution over three years will help support amputees and provide prostheses for newly identified victims.
Greg Hunt, Parliamentary Secretary to the Australian Minister for Foreign Affairs, said the programme had already helped thousands of survivors who might otherwise have been left destitute.
"Since 1995, the fund has assisted more than 15,000 amputees in Vietnam, or almost one-fifth of amputees in the country," he said in a statement.
"In 2006 alone, about 3,000 newly identified amputees were fitted with new prostheses and were supported through rehabilitation offered by the fund."
Hunt said the poor were particularly vulnerable to being injured by landmines.
"They are more likely to be handling mines and unexploded ordnance as a source of scrap metal from which to earn a living," he said.
"Landmines and unexploded ordnance continue to pose a serious threat to development in Vietnam , particularly in rural areas where they are most prevalent."
The funding will also help the Vietnam Government provide training to enable the production of high quality prosthetics and orthotics.
The boost is part of Australia ’s A$75 million commitment for mine action globally from 2005-2010.

Sri Lanka: Japan funds for two social development projects for tsunami affected people in east and south areas
The Government of Japan provided a sum of US$ 69,355 (approximately Rs. 7.5 million) towards two social development projects namely, "Infrastructure Development for Tsunami Affected People in Ampara District" and "Comprehensive Rehabilitation and Participation in Mainstream Development for the Differently Abled Persons in Hambantota District". The signing of the Grant Contracts took place at the Embassy of Japan on 15th February 2007 between His Excellency Mr. Kiyoshi Araki, Ambassador of Japan and the representatives of the two respective organizations. Mr. Douglas Nanayakkara, Director/Registrar, National Secretariat for Non Governmental Organization, Ministry of Social Service & Social Welfare and Dr. Yuji Miyahara, First Secretary, Embassy of Japan and officials of each Organization were also present at the ceremony. The two projects are as follows;
1. "Infrastructure Development for Tsunami Affected People in Ampara District"
The tsunami that struck the island in 2004 has caused much destruction to people, property, and the environment. Ampara is one of the worst affected Districts with a highest number of deaths. A number of rehabilitation and reconstruction projects have been implemented since the tsunami. However, there are more needs such as development of small-scale infrastructure to be fulfilled.
Under the project, construction of a community center in Sainthamaruthu and renovation of rural road in Maruthamunai will be implemented. The Community Center with sanitary facilities will be utilized to conduct a pre-school for children affected by the tsunami. It also will be used to conduct community meetings and health clinics for tsunami affected people in the area. The renovation of rural road will improve the living condition of the people and facilitate easy access to schools and market places, which will benefit over thousands of people living in the Ampara District.
The project is to be implemented by the Rural Development Foundation (RDF). This is the third such occasion where the Government of Japan has provided funds to RDF for rural development projects in Ampara and Mannar.
2. "Comprehensive Rehabilitation and Participation in Mainstream Development for the Differently Abled Persons in Hambantota District"
The project in Hambantota is aimed at providing comprehensive rehabilitation services to differently abled persons.
Although policies and legislations in the country are adequate, implementation has not been effective enough. In the field level, there is a shortage of volunteers who could conduct comprehensive rehabilitation.
In this context, the project has designed to provide training for 30 volunteers on community based rehabilitation including proper identification of differently abledd persons, collect and maintain records, assist in providing physio therapy mainly for children, etc. Under the project, seminars are also to be organized for 80 government officials from 25 Grama Niladhari divisions of Ambalantota Division and other 30 officials attached to the organizations of differently abled peoples on capacity building. In addition, necessary materials for rehabilitation such as Prosthetics, Orthotics and other mobility aid are also to be procured utilizing the funds.
The project will benefit over 16,000 persons living in Ambalantota, Okewela and Tangalle Divisions.
Navajeevana, a national Non-governmental Organization (NGO) established in 1987, has been engaged in offering holistic care at grassroots level to differently abled persons, and will implement the project with the support from the community.
The Government of Japan gives priority for social development through its Official Development Assistance (ODA) scheme implemented in Sri Lanka based on its recognition that sustainable economic development can only be achieved under stable social environment.

Amputees Learn to Walk by Using High-tech Device
By Josh Premako Senior Staff Writer
Wednesday February 14, 2007
BAKERSFIELD --Like pretty much every child, Norman Furr learned to walk as a toddler.
However, at age 9, he had to learn all over again.
Now 63, the Sand Canyon resident had his left leg amputated above the knee after a car accident when he was 9 years old.
His first prosthetic was carved from willow wood.
On Tuesday morning, Furr joined a small group in Bakersfield to test out the cutting edge in prosthetics.
Loaded with sensors and microprocessors, the C-Leg artificial leg manufactured by Otto Bock Healthcare LLP adjusts itself 50 times per second to changes in walking speed and direction, said company representative Mike Callahan.
"It takes the thinking out of walking," Callahan said.
While in the past, amputees wearing a prosthetic leg had to focus on walking and watching for obstacles, he said the battery-powered C-Leg is of a much more intelligent design that acts and reacts more like a natural limb.
Released about a decade ago, the C-Leg has been available in the U.S. for seven years, and Callahan said there are in excess of 10,000 units in use nationwide.
Depending on one's insurance coverage, Callahan said the price of a C-Leg can hover in the $40,000 range.
Calibrated on a laptop by a certified technician, the C-Leg can be set to two modes. For example, the user can have a walking mode, or switch to a mode more apt for bicycling.
A golfer for four years, Furr was curious if an improved rotation feature of the leg could help improve his game.
After being fitted with a trial model, the retired insurance agent practiced walking back and forth, his hands gripping balance rails. Though the C-Leg is even more advanced than his present prosthetic, his muscles worked against the C-Leg, instead wanting to fall into the habit of his normal hydraulic leg.
Furr did not seem immediately thrilled with the high-tech prosthetic, and Keith Sardo of VIPO's Newhall office said that there is often a greater learning curve with someone who is used to a certain type of prosthetic.
Tuesday's event took place at the Valley Institute of Prosthetics and Orthotics, a stop of Otto Bock's Road Show, a traveling presentation of the C-Leg, which in this case included Furr and three others being fitted for and testing out the leg.
Like Furr, 39-year-old Robert Watson of the San Fernando Valley lost his leg in a car accident.
Art Handy, 59, lost his leg during the Vietnam War.
Born without a tibia bone in her left leg, Katie Walker, 17, has worn a prosthetic throughout her life, and was recently accepted to the California State University system on a golf scholarship.
Also at VIPO on Tuesday was Maya Winfrey, a 28-year-old patient model for Otto Bock.
Her left leg was amputated seven years ago after a car accident, and she said she has been wearing a C-Leg for four years.
"I don't fall as often," she said, and added that she can walk farther with the C-Leg, a plus in pedestrian-oriented New York City, where she is a graduate student.
While there are psychological aspects to deal with when one loses a limb - not to mention having to learn to walk again - it's not impossible, Winfrey said.
"This is just another hurdle to get past," she said. "It doesn't need to affect my life in unmanageable ways."
Indeed, Winfrey said she maintains the active lifestyle she had before the amputation, jogging several times a week and recently learning to ski.
There have always been challenges to having lost a limb, but Furr said he can't even count on one hand the number of times he's been angry about it.
"I have a strong belief in God and his influence on my life," he said, and added that he can look back and see what he was saved from, such as serving - and potentially dying - in Vietnam.

Ampara was one of the worst affected districts with a highest number of deaths. Since the tsunami, a number of rehabilitation and reconstruction projects have been implemented. However, there are more needs such as development of small-scale infrastructure to be fulfilled.
Under the project, the construction of a community center in Sainthamaruthu and renovation of the rural road in Maruthamunai will be implemented.
The Community Center with sanitary facilities will be utilised to conduct a preschool for children affected by the tsunami.
It will also be used to conduct community meetings and health clinics for the tsunami affected in the area. The renovation of the rural road will improve the living condition of the people and facilitate easy access to schools and market places, which will benefit over thousands in the Ampara district.
The project is to be implemented by the Rural Development Foundation (RDF). This is the third such occasion where the Japanese Government has provided funds to RDF for rural development projects in Ampara and Mannar.
Comprehensive Rehabilitation and Participation in Mainstream Development for the Differently Able Persons in Hambantota District:
The project in Hambantota is aimed at providing comprehensive rehabilitation services to differently able persons.
Although policies and legislations in the country are adequate, implementation has not been effective enough.
In the field level, there is a shortage of volunteers conducting comprehensive rehabilitation.
The project has designed to provide training for 30 volunteers on community based rehabilitation including proper identification of differently abled persons, collect and maintain records, assist in providing physiotherapy mainly for children, etc.
Under the project, seminars are also to be organised for 80 government officials from 25 Grama Sevaka divisions of Ambalantota Division and other 30 officials attached to the organisations of differently able peoples on capacity building. Materials for rehabilitation such as prosthetics, orthotics and other mobility aid are also to be procured utilising the funds.
The project will benefit over 16,000 persons in Ambalantota, Okewela and Tangalle division.
Navajeevana established in 1987 has been engaged in offering holistic care at grass roots level to differently able persons, and will implement the project with the support from the community.
The signing of the grant contracts took place at the Japanese Embassy on February 15 between Japanese Ambassador Kiyoshi Araki and representatives of the two organisations.

Medical care for Palestinian children
Medical care for Palestinian children U.S. group arranges local and overseas treatment - Matthew Kalman, Chronicle Foreign Service

(03-02) 04:00 PST Jebaliya Refugee Camp, Gaza -- Smiling and laughing, Oday el-Jamal was playing soccer in the garden when visitors came calling at the family home in the Jebaliya refugee camp north of Gaza City.
The handsome 7-year-old with unruly brown hair seemed not to have a care in the world -- until he removed his sneakers and rolled down his trousers to reveal a leg that ended in a fleshy stump just below his knee. The rest of his leg and the foot that moments before had been kicking a soccer ball across the yard was made from metal and plastic.
Oday's leg was blown off last September by shrapnel from an Israeli tank shell, which destroyed the house next door and sent jagged pieces of debris flying into his garden as he played there. His left foot was still intact, but only just, the bones twisted and deformed. His whole body was covered with angry pink craters, his young skin punctured by the deadly shards of metal.
This month, Oday will be in San Francisco, where doctors at UCSF Hospital will perform corrective surgery on his left foot and he will be fitted with a prosthetic right leg made just for him and taught how to use it.
"We thought he was dead," said his mother, Karima el-Jamal. "He was playing out in the garden and we heard an explosion, and next thing we knew the ambulance had rushed him off to Shifa Hospital in Gaza City. When we got there, he was in intensive care. The doctors said it was touch and go.
After a few days, the little boy was transferred to Soroka, an Israeli hospital in Beersheba, where he remained for two months before he was transferred to Alyn, a specialist Israeli orthopedic center in Jerusalem.
"The Israeli doctors did everything for him. They operated on the wounds in his abdomen and tried to save his leg, but they couldn't," she said.
He was fitted there with a temporary artificial leg, which is already broken. Although the Israelis agreed to treat Oday, because of the political tensions between Israel and the Palestinian Authority, he and his mother were unable to stay in Israel any longer. Back in Gaza, he cannot receive the care he needs to resume normal life.
His case came to the attention of the Palestine Children's Relief Fund, which contacted Walter Racette, director of orthotics and prosthetics in the UCSF department of orthopedic surgery. Racette agreed to donate the services required so Oday can be fitted with a prosthesis and learn to use his new leg. His mother will stay with Oday during his recovery.
Oday is just one of hundreds of Palestinian children to benefit from the work of the Palestine Children's Relief Fund, a charity based in Ohio that every year sends dozens of young patients in need of surgery to the United States and Europe, and brings in teams of specialist doctors to treat urgent cases in the West Bank and Gaza.
Last year, the charity raised close to $40 million. According to director Steve Sosebee, it has provided medical services worth more than $400 million, none of which was normally available to Palestinians.
One recent afternoon in Ramallah General Hospital in the West Bank, Dr. Aijaz Hashmi, a pediatric heart surgeon from Loma Linda University Children's Hospital in San Bernardino County, was inserting a catheter into the heart of Randa Abu Shamsiyeh, a 12-year-old girl from Hebron who was born with a heart defect that dramatically reduces the amount of oxygen in her blood.
"This should have been treated 10 years ago, and cannot be done here because they don't have the necessary post-operative care," said Hashmi, who was ending a whirlwind week of clinics and operations.
It was Hashmi's first time in the West Bank. He came with a team of doctors and nurses from Loma Linda who saw more than 130 heart patients in clinics in Jenin, Ramallah and Bethlehem, and performed eight procedures.
"It's extremely rewarding, very gratifying," he said. "If we don't do this, who else is going to do it? We're blessed that we can take the time off."

Experts build legs for amputees
Warren-based nonprofit will take prostheses from Clinton Twp. to the Dominican Republic
February 25, 2007

They are standing at the wait, about 30 artificial legs -- tall ones, short ones, metal ones, plaster ones. Soon they will leave the hallway of a Clinton Township prosthetics clinic and end up in a hospital in the Dominican Republic, where they'll help people who have waited years for a limb so they can walk again.
The mission to the Caribbean nation by a group of local prosthetics experts, two of them amputees, originated with Warren-based M-STAR (Michigan Society to Advance Rehabilitation).
M-STAR founder Dr. Saul Morris is a retired physician assistant and psychiatrist from Warren who uses a prosthetic leg. St. Clair Shores resident Bob Maniere, also an amputee who walks with an artificial leg, is president and co-owner of Comfort Prosthetics and Orthotics in Clinton Township. They are two of the five doctors and prosthetics experts making the trip as volunteers providing a free service to people in need.
They plan to depart March 1 and return March 11.
"With me being an amputee myself and Saul being an amputee we feel strongly about getting people on their feet," said Maniere, who lost his leg jumping on a train as a teenager. Morris' leg was amputated in 2000 due to a condition called peripheral vascular disease.
"We don't know what kind of situation you can run into there," Maniere said last week from his Clinton Township office.
On Feb. 16, he; Morris; Jim Williamson, a registered prosthetics and orthotics assistant from Clinton Township, and David Ballantyne, a certified prosthetist from Harper Woods, were planning for their upcoming trip. Comfort Prosthetics and Orthotics is funding the trip with a donation of between $10,000 and $15,000. That price, however, does not include shipping, which the group didn't count on.
"We come in early. We work on Saturdays," Williamson said.
That is not a complaint, because the outcome could be so profound.
"A father can work again, a husband can help around the house again," Williamson said. "It's the whole family that's affected, not just the patient."
"It's going to be a lot of hard work, but it's worth it," Maniere said. "We'll be moving fast. It would normally take us a couple of months to do 30 patients; we'll do that many in five-six days."
To prepare for the trip, over the last few weeks they have taken parts from donated, unwanted prosthetics and pieced them together to form whole new legs. "Basically, we're taking stuff that would have been thrown away and making good use of it," Morris said.
The legs have come from donations made to M-STAR, as well as from Maniere's patients who have either found their legs ill-fitting or tired of them. Doctors, by law, may not reuse or resell the legs in the United States, in part to protect patients from being sold second-hand prosthetics instead of new ones.
"We might as well get someone walking with them," Maniere said.
It took between two and three weeks to turn the donated, disassembled pieces into new complete legs. Legs of all kinds -- pneumatic, hydraulic, starter legs, waterproof legs, light-skinned legs and dark-skinned ones.
In the Dominican Republic, the legs that were rebuilt here will be matched with patients. The doctors will work in the prosthetics facility at a rehabilitation hospital in Santo Domingo that includes an oven for baking casts and tools for shaping and cutting them.
If necessary, Dr. John Sealey, vice chief of staff and a vascular surgeon at St. John Riverview Hospital in Detroit, where Comfort Prosthetics and Orthotics also has an office, will operate to correct problems common in amputees.
The group will also teach the hospital's prosthetics technicians "30 years worth of experience so that they can go forward into the future and do more for their patients," Maniere said.
"In the Dominican Republic you probably have somewhere around 4,000 amputees waiting for limbs," Maniere said. "They can't get the parts first of all, and they've usually cost too much. A lot of what they do have comes from the black market."
The legs coming from Michigan range in price from nearly $2,000 each to as much as $8,000 each, for a total worth of about $250,000, Maniere said.
What Morris has dubbed "Operation Compassion" began when a Dominican-born New Jersey woman called him at M-STAR to say she wanted to get artificial legs there "to help her people," Morris said. She is making the trip as well.
That led to a call by Morris to Maniere and company, just the latest in a long line of requests for favors. "He comes to us a lot," Maniere says. Everyone laughs.
The stories of those for whom Morris asks favors, however, are far from comical.
There was the girl from Gambia who was wearing a wooden leg that fell apart. She was brought to Clinton Township from Wisconsin and given a specially built leg and "finally wore a dress for the first time," Morris said.
They helped a Bolivian farmer who up until four months ago had rigged up a pipe to use as a leg.
Morris became a philanthropic prosthetics provider after he was asked to speak to an advocacy group for the disabled.
"They asked me to speak about my experience not long after I lost my leg," Morris said. "I said 'Go to hell. I don't want to talk about this.' I finally started reading up and I just realized I'm trained in medicine and I'm not understanding this and feeling bad about myself. I decided to dedicate myself to helping amputees then."
Besides providing prosthetics, Morris, at no cost, visits hospitals to counsel and advise new, often confused, angry or depressed, amputees. He goes to their homes. He hears from people who want to use an arm or a leg again but don't have the means. He's hearing more from families of soldiers in Iraq or from the soldiers themselves.
"It's pretty hard when you can't say yes to whatever they need," said Morris, who is provided a small monthly stipend by Comfort Prosthetics and Orthotics in order to work on his low-budget M-STAR project.
Said Maniere, "Without Dr. Morris finding the people who need help and getting hold of us, none of this would be happening."
They all are looking forward to changing some lives for the better.
"When you see the people walking, all the work you put in, all the dollars that were spent won't matter," Maniere said. "Plus, it's fun. . . . We hope we can make this a yearly thing."

Management of Bilateral Lower Extremity Amputees
In response to e-mail, regarding care and rehab of bilateral lower extremity amputees, here is a very good article from The American Academy of Orthotists & Prosthetists.
BILATERAL LOWER LIMB PROSTHESES
Jack E Uellendahl, CPOHanger Prosthetics and OrthoticsPhoenix Arizona
The bilateral lower limb amputee poses unique challenges to the rehabilitation team as they seek to restore functional mobility. Modern fitting techniques and state-ofthe- art componentry allow for improved function and comfort compared to what was possible in the recent past. As medical care and rehabilitation techniques continue to improve, patients are living longer, resulting in an increase in the number of bilateral amputations. Esquenazi reports that fifty percent of the patients who suffer a lower limb amputation because of disease are at risk for a second amputation within 3 years. In light of these statistics, it is imperative that the healthcare professionals serving the needs of amputees are well versed in the special needs of the bilateral amputee.
Factors that influence the successful rehabilitation of the bilateral lower limb amputee are numerous. The level of limb loss, particularly the presence of physiological knee joints and the general strength and health of the amputee are key indicators of the successful use of prostheses. Careful attention to the details of socket fit, prosthesis alignment and component selection following sound prosthetic principles along with the services of an experienced rehabilitation team will optimize the ambulation potential of the bilateral amputee. Given these advantages and the determination of the amputee to succeed, a positive outcome is attainable. The rehabilitation team should maintain an open mind. Thoughtful use of available assistive technologies including, but not limited to, state-of-the-art prosthetic components can be of significant benefit to the bilateral amputee.

Campaign for Prosthetic Coverage
ACA Advocacy Staff
Almost two million Americans are living with limb loss or limb deficiency as a result of disease, trauma or birth defect.
In a December 2005 to January 2006, a poll of 660 users of the ACA web site, 423 (72%) of respondents had private insurance. In return for premiums paid for group health insurance, consumers expect to be covered for catastrophic illness or injury. Sadly, without legislation to ensure coverage, many people living with the loss or absence of a limb are facing discouraging obstacles when trying to obtain prosthetic care. Current changes in insurance plans are having a devastating effect on amputees and their families:
62% reported that their prosthetic coverage had remained the same in the past three years.
31% indicated that it had been reduced,
7% said that it had been eliminated.
In answer to a growing number of calls from our members and friends who are finding it difficult to afford an appropriate prosthesis, the Amputee Coalition of America (ACA) launched the Action Plan for People with Limb Loss (APPLL).
APPLL works nationwide at the grassroots level to motivate people to inform lawmakers about the critical need for all amputees to have access to an appropriate prosthesis, regardless of their financial circumstances.
Our goals:
1) Pass prosthetic parity laws in all 50 states.
2) Work at the federal level to ensure that all amputees receive the help they need to obtain adequate and appropriate prosthetic care.
We have already made exciting progress! In 2006, we worked with eight states to advance legislation requiring coverage for prosthetic devices and components. Three of the eight states passed legislation.
In 2007, eleven states will introduce or re-introduce legislation for prosthetic coverage. Another eight states are working to build campaign committees to advance legislation.
But we need your help!

Bionic Leg Helps One Man Walk Tall
It may sound like something from a science fiction movie, but a bionic leg with a computerized brain is helping one Georgia man do something he hasn't done in six years, walk without a limp.When Mario Cieplinski was just 20-years-old, he lost his left leg in a conveyor belt accident, but he never lost his spirit."That's not going to stop me. I was going to enjoy life," said Cieplinski.Cieplinski started with a mechanical knee and then he got his lighter, sleeker C-leg. Then he got a huge boost with a power knee, a bionic leg with a computerized brain."It's truly the future of prosthetics," said Nancy Kaselak of Hanger Prosthetics and Orthotics.The small device is strapped to Cieplinski's good leg and Bluetooth technology mimic his movements and sends the information to the power knee which can propel up and down inclines and push through obstacles like tall grass or rocks."We see so many amputees and what they lack and we wish we could give back to them and can't. This knee can," said Kaselak.Cieplinski is the first Georgian to try out the power knee and one of only 12 people in the world who has one, and it's a gift he is well aware of."To have something basically as close as my real leg, it means a lot. Even if it makes sounds, it's so close to a normal person," said Cieplinski.Cieplinski hopes that other amputees will soon be able to follow in his footsteps.

Tsunami survivors face future
ALMOST two years ago, in the wake of the deadly Boxing Day tsunami, Acehnese girl Delisa had a couple of wishes.
One was for a new leg to replace the one she lost in her battle to survive the mountainous waves that swamped her homeland. The other was that she be able to return to school and keep learning.
Now, as the second anniversary of the earthquake and tsunami approaches, Delisa has a new leg but she still relies on crutches to get around the house, only utilising the new limb when she is going out.
She has gone back to a new school but not to her old classmates – most of whom were killed in the tsunami – and is now ranked fourth in the class.
Delisa's mother and older brother and sister were all killed in the tsunami – among the 160,000 killed or missing in the Indonesian province of Aceh, which was closest to the earthquake's epicentre and bore the brunt of the resulting tsunami.
On November 12 this year, a date circled on the family's calendar, her father Bachtiar married Sabariah, a widow who had lost her husband and baby in the tsunami.
"Delisa used to go to her house often and one day she asked Sabariah if she would like to be her new mum. She came home and told me to marry her," Bachtiar tells from the home, where the family has set up a small convenience shop in the front section.
Authorities say it will take another three years to rebuild Aceh and that 48,000 of the 128,000 new homes needed have so far been built.
And Delisa is not unlike other amputees. Her prosthetic left leg was donated by a Malaysian charity – however it is not the right size, the knee is in the wrong place, it is uncomfortable to wear and she cannot walk without crutches.
A second prosthetic, from Indonesia, is even worse. It is old-fashioned and so heavy she can barely lift her leg with it on.
"I wish I could have a proper one, a good one. I only wear it to school but for other daily activities I don't wear it because it's not comfortable," she said.
"Sometimes I feel sad because I can't follow my friends to play around."
Delisa still has vivid memories of the tsunami, of her battle to survive and of losing her family but, like so many others, says she "tries to forget".

The Open Prosthetics Project
The Open Prosthetics Project is producing useful innovations in the field of prosthetics and giving the designs away for free. By substituting public good for profits we believe that we can generate far more societal benefit than if we commercialized and sold our ideas. This project is an open source collaboration between users, designers and funders with the goal of making our creations freely available for anyone to use and build upon.
Prosthetics Research Study "Replacing limbs. Restoring lives."
Prosthetics Research Study is a multidisciplinary research team with a goal to preserve the limb at risk and improve function for the amputee. PRS was founded in 1964 with Dr. Ernest M. Burgess, orthopaedic surgeon, as Director and Principal Investigator. Its inception followed an international conference in Copenhagen where Dr. Michel Berlemont of Berck-Plage, France and Dr. Marion Weiss of Warsaw, Poland introduced new ideas of lower limb amputee surgery. They provided a way to shorten the amount of time spent before an amputee was rehabilitated and walking with a prosthesis. Dr. Robert E. Stewart (Veterans Administration Chief of Prosthetics and Sensory Aids) decided to set up research in this area of Immediate Post-Operative Prosthetics (IPOP), and he asked Dr. Burgess to head a center to do this.
Prosthetics Research Study has followed their mission by working with patients all the way through the process, from risk evaluation through amputation and rehabilitation. Since 1964 our research has included varying areas along this path.

Defense Advanced Research Projects Agency
HistorySince its inception in 1958, DARPA has utilized the existing contracting organizations in the military services to award DARPA-funded contracts. These contracting organizations, along with the financial management activities that support them, are referred to as DARPA "Agents". DARPA's use of these 89+ agents has been governed by memoranda of agreement with the three services. In FY87, DARPA created its own internal contracting agent called the Contracts Management Office (CMO). CMO was never intended to replace the contracting agents in the military services, but rather to provide DARPA with additional contracting capability and flexibility in certain restricted areas critical to the DARPA mission. At first, CMO concentrated on prototyping projects. Over the years that mission concentration shifted to special support for consortium programs, fast-reaction projects, and awards under the DARPA agreement authority of 10 USC 2371. The CMO staff deliberately has been kept small (a total of 15 billets), but is highly-trained, highly-graded, and extremely productive, awarding approximately 27% of the total contracting dollars.
Statistics
CMO has the authority to award contracts, grants, cooperative agreements, and "other" transactions. Although this provides great flexibility, it creates statistical and record-keeping problems which are not evident in most contracting organizations. For example, the CMO statistics on contract awards only are reported to the U.S. Army Contracting Support Agency through the DD350 system, the same system to which Army and other DoD agencies report their contract statistics. These CMO statistics, however, do not reflect the many millions of dollars awarded by CMO under grants, cooperative agreements, or other transactions. Those dollars must be captured in other data systems and combined with the Army contracting figures to give the true picture.
Otto Bock Bionic Arm and some other new devices from Otto Bock
July 2005Otto Bock Bionic Arm - World First for MelbourneThe 11th of July 2005 saw the release of the 12K100 ‘Dynamic Arm’ by Otto Bock. This ground breaking Electronically Powered Elbow had its premier world wide fitting at Caulfield General Medical Centre. The Premier of Victoria, the Honorable Mr Steve Bracks, officially released the 12K100 at a ceremony held at Caulfield General Medical Centre. Mr Bracks was very pleased to announce that Australia had been chosen as the site for the market release of such a technically advanced product in the field of Upper extremity prosthetics.
The 12K100 utilises state of the art mechatronics, battery technology, as well as CPU technology that has recently been developed for the automobile industry. This means that the 12K100 is considerably faster and stronger than other elbow units (able to lift approx. 6 times more weight), as well as having a longer battery activity time.
Peter Eberle, the patient fitted at Caulfield, was wearing another type of elbow unit at the time he was fitted with the 12K100. He was amazed with responsiveness as well as the reduced weight of the 12K100. A first for Peter was that he was able to flex/extend his elbow at the same time he could open/close his hand or rotate his wrist. The ‘Axon Bus’ system of the 12K100 meant Peter was able to carry out two tasks at once, which also is a first for powered elbows.
Kevin Harrison, Professional Services Specialist, will be running workshops to demonstrate the 12K100 ‘Dynamic Arm’ in the future. Therefore if you would like to have a first hand demonstration, or maybe you have a client who you would think may benefit from this revolutionary elbow unit, please do not hesitate to call our customer service on 1300 136 053 for more details
The 12K100 utilises state of the art mechatronics, battery technology, as well as CPU technology that has recently been developed for the automobile industry. This means that the 12K100 is considerably faster and stronger than other elbow units (able to lift approx. 6 times more weight), as well as having a longer battery activity time.
Peter Eberle, the patient fitted at Caulfield, was wearing another type of elbow unit at the time he was fitted with the 12K100. He was amazed with responsiveness as well as the reduced weight of the 12K100. A first for Peter was that he was able to flex/extend his elbow at the same time he could open/close his hand or rotate his wrist. The ‘Axon Bus’ system of the 12K100 meant Peter was able to carry out two tasks at once, which also is a first for powered elbows.

The Utah Arm 3
Since 1981, the Utah Arm has been the premier myoelectric arm for above elbow amputees. It was originally developed at the University of Utah by the Center for Engineering Design, led by Dr. Steve Jacobsen. In 1987, Motion Control released the Utah Arm 2, with entirely re-engineered electronics that made the Utah Arm the most durable and dependable myoelectric arm avaialable.
The Utah Arm 3 - One Step Closer to Nature
In 2004, Motion Control introduced microprocessor technology into the Utah Arm 3 (U3), with a Computer Interface that allows the prosthetist or wearer to fine-tune the adjustments to achieve maximum performance. A variety of inputs may be used, so more options are available to more wearers. Meanwhile, the U3 still delivers the same sensitive, proportional control of elbow, hand and wrist (optional), letting the wearer move the arm and hand slowly or quickly in any position.This provides a more natural response with less effort than the traditional on/off movement.
WHAT’S NEW ABOUT THE U3?
Simultaneous Elbow and Hand control! Because the Utah Arm 3 has two microprocessors, two functions can be controlled at once (optionally), thus producing a more natural movement.
More Input Options
EMG Preamps using disc or snap-type electrodes
Motion Control Linear Potentiometer
Motion Control Force Sensor
Otto Bock Linear Transducer
NEW Touch Pad design!
Allows convenient placement wherever a "push" input is available
Protects the sensitive transducer from water, sweat and sharp edges
Compatible with U3, ProControl and ProHand controllers.
Easy to Use Computer Interface- For adjustments by the prosthetist
The Set-Up Wizard guides you through the process of setting up your system step-by-step. Once set up, users can readjust by routing directly to the adjustment screens.
The wearer's input signals are shown in real time on the Computer Interface,
so adjustments can be made quickly for immediate testing and training.

The Proprio Foot
The world's first intelligent foot module, the PROPRIO FOOT provides unprecedented physiological benefits for transtibial amputees. A wide and automated range of ankle flexion with proven Flex-Foot dynamics means function is as close as you can get today to the human foot.
The PROPRIO FOOT thinks for itself, responding beautifully to changing terrain and transforming the approach to stairs and slopes, as well as level-ground walking. Angling itself appropriately, it also helps amputees to sit and stand up easily and more naturally. The PROPRIO FOOT™ also has a calibrated alignment control feature. Overall, the effect is a feeling of improved proprioception with a more balanced, symmetric and confident gait with reduced wear and tear on the back, hips and knees.
Performance benefits:
Cutting edge sensor technology and artificial intelligence identifies sloping gradients and the ascent or descent of stairs after the first step, and instructs the ankle to flex appropriately. Users can place the foot fully on a step when climbing or descending stairs and it will automatically adapt its ankle position to enable the next step.
This active ankle motion also allows users to tuck both feet back behind their knees when getting up from a chair or sitting down. It also points the 'toe' down for a more natural appearance once seated. When walking, it automatically gives the 'toe' a lift at the exact moment in swing phase that will allow sufficient ground clearance.
This anatomically correct response creates a more symmetrical and balanced gait, reducing the need both to ?hip hike? when walking or compromise stability by rolling over the edge of a step when going down stairs. Nor is there any need to load the entire body weight on the sound limb when getting out of a chair.
Despite its sophisticated technology, the PROPRIO FOOT has an extremely user-friendly design and is easy to set up and operate. During a simple calibration process involving 15 steps the device evaluates and memorizes an individual?s unique gait pattern. It also has a calibrated alignment control feature.
OMEGA Tracer System
OMEGA Tracer System provides practitioners with the latest in CAD software, shape capture devices, and tools designed specifically for the O&P industry. Plus, Ohio Willow Wood offers complete training and support. OMEGA Tracer allows prosthetists to set themselves apart as professionals.
Powerful CAD Software
• Prosthetics Software provides practitioners the ability to capture upper and lower limb shapes via the OMEGA Scanner, T-Ring™ II, or the Tracing Pen and Tracing Wand. AK shapes can also be created by measurements of the limb. An amazingly broad suite of modification tools are included that allow practitioners to replicate plaster modification techniques within this unique software. Sockets and custom liners of all types, including upper extremity, are created more efficiently.
• Orthotics By Measurement Software enables practitioners to create and modify shapes with the user-friendly Tracer Technology. This proven software allows practitioners to develop accurate spinals, AFOs, and knee braces with amazing time-savings. The spinal software utilizes a library of hundreds of templates to combine with patient measurements to create a customized spinal shape. AFOs are similarly created through the use of templates, measurements and a unique set of shape modification tools that allow practitioners to clearly customize the shape to match the patient's anatomy.
• Alpha DESIGN® Liner Software is the tool that allows prosthetists to create new custom Alpha Liners for transtibial, transfemoral, transradial and transhumeral amputees. Practitioners can tailor the gel pattern and thickness to the unique contours of residual limbs. Type and color of fabric can also be custom.
Once practitioners are satisfied with their patient-specific liner design, files can be sent to Ohio Willow Wood electronically via Internet access.
Transfemoral amputees can take advantage of the AK Comfort Cuff, an add-on feature that provides more comfort and extends liner life. The AK Comfort Cuff is fabric placed on a DESIGN AK Liner's interior, that when donned, is rolled down over the socket brim. The cuff protects the Alpha gel from exposure to harmful wear and tear. Additionally, silver microbial fabric is used on the cuff to reduce any odors from wearing the liner all day.
The software includes enhanced Alpha DESIGN Liner Modification Tools, allowing any aspect of a previously created DESIGN Liner to be modified without losing the existing gel pattern. The improved modification tools allow practitioners increased control and flexibility.
Extremely Accurate Shape Capture Devices
• OMEGA Scanner is the latest in shape capture technology. It is a 3-D laser imager that utilizes reflectors on the limb to capture limb shapes accurately. Limited patient movement during scanning does not impact the scanner's ability to capture an extremely accurate shape. The hand scanner can be used for both prosthetic and orthotic applications. It is fully integrated with OMEGA Tracer software.
• The T-Ring™ II captures shapes in less than a second with its four digital imagers and four projectors. White socks or liners are all that is necessary for the T-Ring II to capture prosthetic limb shapes accurately with a simple click of a button.
• Tracing Hardware provides practitioners the ability to capture and make modifications directly on the patient's limb. Tracing a limb is an interactive process that allows a more "hands-on" approach for the practitioner. The Tracing Hardware (Black Bag) includes the Tracing Pen, Tracing Wand, and Digital Calipers. Practitioners can also use the Tracing Wand to duplicate an existing socket shape digitally.
Innovative Shape Modification Tools
• Advanced Dual Model View Tools provide the ability to visually compare two shape files simultaneously. The new view tool allows practitioners to align files proximally, distally, or by landmark location, to change color of each model, and to specify if views of models are to be solid, transparent or wire frame. This feature allows practitioners to see and/or prove clinical and patient advancement that can be used for clinical analysis of patient progress over a period of time.
• Ramus Containment Socket Tools enables the design of a new AK socket style. A tab locks the socket onto the medial side of the descending ramus and the socket brim is no longer under the ischium, allowing AK amputees more comfort and freedom.
• Relief Pads and Symmetry Tools allow practitioners to make relief pads in custom shapes and for reliefs to be easily transposed to the opposite socket side. These tools can be used on prosthetic and orthotic shapes.
• The Trimline Tool enables practitioners to draw a trimline on prosthetic or orthotic models created by measurements or to existing shape files. The tool includes several options such as smoothing and enhancing the trimline, symmetry, and adding ridges to the trimline among others. These options can make the trimline more efficient and accurate.
Ohio Willow Wood and oandp.com have partnered. OMEGA Tracer now has integration functions with the OPIE Practice Management Suite software. For practitioners who own both OPIE Suite and OMEGA Tracer, the two programs work together and interact seamlessly. This integration permits OMEGA Tracer patient files to be added easily to the digital patient records within OPIE Suites and to track Ohio Willow Wood product purchases within OPIE.
Education and Technical Help
• OMEGA Training and Support is geared to shorten the learning curve and permit the software system to be implemented successfully. For an introduction to CAD, Ohio Willow Wood representatives will visit current and prospective customers' offices to conduct in-facility demonstrations with patients.
Once a facility purchases an OMEGA Tracer system, Ohio Willow Wood wants to make certain the transition to CAD goes smoothly and will troubleshoot any problems or challenging shapes. New users are offered several phases of training, from installation and orientation to prosthetic applications. Practitioners also earn Continuing Education Credits for their efforts with the OMEGA Tracer training, at no additional cost.
Customers receive free software upgrades as developed, keeping control of the latest technology in the hands of owners. Unlimited toll-free phone tech support is also available at no charge. In addition, our OMEGA FAB department is available to help with fabrication.
BioSculptor Othotic and Prosthetic CAD/CAM Systems
The latest addition to the BioSculptor CAD/CAM solutions is the BioScanner™ laser line scanner. The BioScanner™ laser line scanner is capable of scanning any body segment. Direct scan to produce a prosthesis, orthosis, custom liner, knee brace, AFO, seating, TLSO or cranial helmet. This laser scanner produces extremely detailed scans due to its dual camera system. The two cameras give the scanner the ability to "see" the laser line from both sides, which captures the cleanest data. This data is imported directly into the BioSculptor software where shape manipulation is performed.
Osseointegration
Osseointegration - Bone anchored prostheses for above knee amputated patients!
Hundreds of thousands of people all over the world have had a leg amputated due to accidents, diseases or landmines. In 2005 Sahlgrenska University Hospital will be seeing
40-50 above knee amputated patients from outside of Sweden, in order to attach leg prostheses using titanium screws, a process known as osseointegration. The method, in
which Sweden is a world leader, enables above knee amputated patients to live virtually normal lives. Patients with other types of amputation also receive osseointegration treatment.
M.A.S. Socket: A Transfemoral Revolution
M.A.S. Socket: A Transfemoral Revolution
By Miki Fairley
The M.A.S.® socket design is an evolution--and perhaps even a "revolution"--in the development of ischial containment (IC) socket concepts. Since 1999, when Marlo Ortiz Vazquez del Mercado, Ortiz Internacional, Jalisco, Mexico, first unveiled his new design, it has continued to arouse interest throughout the O&P worldwide community. Recently the design was featured in the Thranhardt lecture series during the American Academy of Orthotists & Prosthetists 2004 Annual Meeting and Scientific Symposium.
The new design provides several clinical benefits: patients can sit more comfortably; there is no plastic beneath the gluteus; the prosthesis is easier to don; patients enjoy full range of motion, better functional gait--and important to patients and family members too--much better cosmesis. Seeing a video of patients walking, sitting, and demonstrating the range of motion possible is truly amazing.
Ortiz, who is a prosthetist and engineer, has fit hundreds of patients with the design to date. These patients reportedly have had no difficulty in wearing the socket for long periods of time. In fact, one amputee, due to his work schedule, actually wore the socket for 28 straight hours with no discomfort.
Agnes Curran, CP, OPGA prosthetist, pointed out that the design seems to be surprisingly skin-friendly despite the intimately fitting contours. Generally there is no skin irritation, and some amputees who had worn previous prostheses found that existing skin problems cleared up.
OPGA, Waterloo, Iowa, along with O&P1, Waterloo, hosted an initial seminar in January 2004 in which Ortiz taught how to cast, modify, and fit the design. An office worker who came with prosthetists from Nebraska attending the first seminar served as one of the patient models. She wore her check socket all the way home to Nebraska and asked the prosthetists to come in over the weekend to laminate it so she could begin wearing it immediately. Another patient waited all day for his new socket rather than go home with the old one. This patient enthusiasm is testimonial to their acceptance of this new design.
Bob Tillges, CPO, FAAOP, Tillges Certified Orthotic Prosthetic Inc., Maplewood, Minnesota, is enormously enthusiastic about the new design. At the time of this writing, Tillges, who attended the initial OPGA seminar, has fit nine amputees with the socket and is in the process of fitting two more.
"All my patients have been very satisfied," he said. "They have no discomfort; there's better ischial containment and range of motion. In fact, one of my patients' wives called me and said, "This is the most awesome prosthesis my husband has ever worn! I can't even see it under his slacks." She added that it had always bothered her before when her husband's prosthesis outline was visible.
"I'm taking time to learn and understand the mechanics of Marlo's system, and I'm getting very good results," Tillges added. Although most of Ortiz's patients are younger, Tillges has a large percentage of geriatric amputees. He has fit amputees aged from 44 to 81, including several in their 70s. Four of the 11 use some auxiliary suspension, but the others use true suction suspension only. "These sockets stay in total contact with flexion, extension, adduction, and abduction," Tillges said. "Something that has always bothered me as a professional is when you can see gapping, spaces, or outline of the socket under clothing." Although many were skeptical at first and thought the design would cause proximal tissue roll development, Tillges said, "We have not experienced that problem." He added, "With better ischial containment, you reduce the amount of tension values needed for suction, get more comfort, and achieve better suspension."
Tillges started his O&P career carving and fitting wood sockets in the 1970s; he has seen socket technology develop through 30 years up to the present. Some iterations of the ischial containment concept through the years have included the quadrilateral "quad" socket shape taught by the O&P schools at New York University (NYU), Northwestern, and the University of California-Los Angeles (UCLA). Ivan Long, CP, developed his Long's Line, and John Sabolich, CPO, came up with the Contoured Anterior Trochanteric Controlled Alignment (CAT/CAM) method. Tillges feels that Ortiz has gone beyond these in IC design excellence. He noted how much his patients who have worn other socket designs appreciate the new sockets: "No way do they want to go back to what they had before." Tillges is also educating his company's residents and young practitioners in the technique.
The Design: What Is It?
So, what is the M.A.S. socket? Ortiz describes his design: "It is very important to consider the angle of the ischial ramus. The ischial tuberosity and part of the ramus as well as the medial aspect of the ramus are encapsulated within the medial aspect of the socket brim." Generally, the medial wall is lowered anteriorly to avoid pressure on the ascending ramus; effectively ischioramal weight-bearing eliminates the need for gluteal support, so those tissues can be excluded from the socket, he explained.
In the conventional design, posterior trim lines include part of the gluteus maximus. In the M.A.S. design, the height of the posterior wall has been lowered to the gluteal fold, so the entire muscle belly can be free of the socket. "This will not only improve cosmesis but with this configuration, we have found that ischial tuberosity and part of the ischial ramus are encapsulated more effectively with no restriction in hip movement," Ortiz said.
"With the gluteal cutout, no weight bearing occurs in this area, and weight-bearing forces are vectored from the captured medial aspect of the ramus with a resultant force projecting to the anterior/lateral area of the socket," explained Al Pike, CP, in "A New Concept in Above-Knee Socket Design" (The O&P EDGE, November 2002).
What About CAD/CAM?
Can the design be adapted to CAD/CAM? Perhaps "down the road," is the answer. "The difficulty is not in measuring; it's in being able to modify the complex individual anatomical shapes correctly," said Dennis Clark, CPO. However, he foresees a time when the necessary tools can be incorporated into the CAD software to accomplish the socket design.
"Once people under-stand all the concepts of the design, they can identify what they are not getting from current CAD tools--and then it will be easier to develop what's needed," said John Michael, CPO, FAAOP, who also participated in the January seminar. Michael is a consultant to OPGA and is assisting in the development of the course series.
C-Leg, The Prosthetic High-Tech Explosion
The Otto Bock C-Leg® and Otto Bock Compact™ microprocessor-controlled knees are designed to deliver the best in stability and reliability. Both knees utilize easy-to-charge lithium ion batteries with 40-45 hours of power.
They are appropriate for people who:
Are transfemoral amputees, including those with bilateral limb deficiencies or hip disarticulation amputations
Are involved in activities that require a high level of stance stability
Walk or have the potential to walk on uneven terrain
Frequently descend stairs or negotiate slopes
The C-Leg is Ideal for people who:
Currently are or have the potential to be unlimited community ambulators
Can utilize Second Mode for varied activities such as bicycling, roller-blading, or extended periods of standing
Have the ability or potential to walk faster than 3 mph/5 kph and walks up to or more than 3 miles/5 km a day.
Are involved in activities requiring a high level of stance phase safety as well as efficient swing phase control
Change direction and speed suddenly for work, sport, or home activities.
Would benefit from automatic swing phase adjustments because of their activity level.
Would improve their gait when using stance extension damping
Second Mode Adds Options
C-Leg wearers can choose between two modes that are programmed by their practitioners. The first mode would be optimized for the patient's daily activities while the second mode would be programmed for activities in which the amputee participates. With just a few simple taps of the toe the C-Leg can switch between modes and go from a secure walking knee to a locked knee, such as for a surgeon to lean on during long procedures-or less resistance for a bicyclist who needs a freely swinging knee.
RHEO KNEE® technology in depth
RHEO KNEE® technology in depth
Perhaps a product designer's greatest challenge is to replace all physiologic function of the anatomical limb. Emulating the human anatomical, physiological and neurological system is a holistic task that is both complex and humbling. Anatomically, the designer must recreate structures of the body by using materials that enable everything from fine motor skills to ambulation. Neurologically, the designer must create a feedback mechanism that senses changes in the external stimuli and that uses the character of these changes to alter physiological responses in real-time.
The difficulty of meeting these challenges explains why commonly available prosthetic devices have such limited functionality. It also explains why Ossur turned to the Massachusetts Institute of Technology (MIT) to identify the state-of-the-art software, hardware and biomechanical technologies needed to make bionic prosthetics a reality. The results as realized in the RHEO KNEE® are striking: a synergy of artificial intelligence, advanced sensor and magnetorheological actuator technologies that give the user the unprecedented natural movement essential for embracing life without limitations. The specific technologies that achieve this synergy are the:
Dynamic Learning Matrix Algorithm™ (DLMA).
The RHEO KNEE® utilizes a software based artificial intelligence to learn the individual's walking style and provide a mechanism for continual monitoring and optimization of swing control. From the moment the first step is taken, the Rheo Knee compares the maximum degree of knee flexion achieved in each step during swing phase to targeted values set by the prosthetist with the Rheo Logic software. Swing flexion resistance values are then updated to limit excessive heel rise or promote heel rise depending on the walking speed. Swing flexion resistance values will influence extension rate and extension dampening making the swing phase adaptation process complete. Sampling and optimization of values is continual within the RHEO KNEE® even after the initial program has been set for the user by the prosthetist. Through constant monitoring and optimization, the Rheo Knee provides a virtual prosthetic adjustment to ensure that the individual?s walking style is targeted most appropriately.
This advanced technology uses magnetic fields, MR fluid, and rotary blades to vary the RHEO KNEE?s resistance in real-time. Microprocessor control initiates rapid kinetic response to sensory inputs through inductance command as frequently as 1000 times/second. With application of the magnetic field, carbyliron spheres are drawn together in electromagnetic chains. As the knee rotates into flexion or extension, fine rotary blades shear the particle chains to create resistance. The result is minimized fluid drag within the knee restoring more natural pelvic position during pre-swing and reducing fatigue levels.
Microprocessor Controlled Stance.
Through advanced sensing and processing, the RHEO KNEE® provides multiple safeguards against inadvertent stance release. The knee must be fully extended, momentarily still, and achieve 20% of the average maximum extension moment during each step to release. The microprocessor samples force measurements at a rate of 1000 times per second and is always aware of how the user is loading the prosthesis. Disturbances in the user's path are automatically recognized by the force sensors. Stance support is instantaneously activated to protect the user from a potential stumble and fall. By detecting these patterns in their earliest stages, the RHEO KNEE® can take the preventive actions to reduce the likelihood of a fall.
Rheo Logic Software.
This intuitive icon-based programming software runs on an HP iPAQ palm-based computer and makes operation simple. With the use of specialized SETUP modes, initial programming is automatic. You simply power the unit and have the user walk. SETUP modes calculate baseline starting values for swing and stance control. When manual adjustments are necessary to further customize the RHEO KNEE®, the software makes this task a fast and easy one. Multiple users and settings per user may be stored on the PDA and transferred to a PC making this tool very versatile.
No magnetic field applied to the MR fluid. Ironparticles are diffusing randombly allowing the disks to rotate freely in the opposite direction. Low magnetic field applied to the MR fluid. The iron particles start forming chains and resistance between the blades increases. The strong magnetic field has now caused the fluid to form continous chains and the knee can now been felt as rigid through the joint.
Clinical test results
In 2003, a study described in Industrial Robot (International Journal, Vol. 30, ~1 2003, P 42-55) assessed the clinical effects of the RHEO KNEE® by examining kinematic data from four subjects who were unilateral, transfemoral amputees. The investigators concluded that a user-adaptive control scheme and local mechanical sensing were minimally sufficient to enable amputees to ambulate in a biologically realistic manner (as compared against the schemes and sensing available in mechanically passive prostheses).
