Iraq injuries benefit from advances in prosthetics

Hundreds of American soldiers have returned from fighting in Iraq and Afghanistan as amputees, with more than 100 having lost multiple limbs. Improvements in prosthetics are restoring mobility and productivity to these injured heroes.

One of the innovations is microprocessor knees, which make hundreds of calculations per minute to adapt to a user's gait. Another is targeted muscle re-enervation, which reroutes nerve signals in an amputee's residual limb, allowing him or her to "feel" and sense movement in the artificial limb.

In addition to soldiers, civilians reap the benefits of advanced prosthetics and increased funding for research. Heather Mills, a belowknee amputee, was highly praised for her appearance on ABC's "Dancing With the Stars." Oscar Pistorius, a 20yearold South African double amputee who competed in Athens at the 2004 Paralympics, is now running the 200- and 400-meter sprints fast enough to earn a spot on the official Olympic team.

Although the advances in orthotics (orthopedic braces) and prosthetics are considered good news stories for many, there are still challenges to overcome. Comparing Medicare payments in 2003 against 2005 payments, dollars paid for orthotic and prosthetic devices declined while the number of devices provided increased.

"We need some basic protections to assure that both government and private insurers provide appropriate reimbursement and coverage for orthotics and prosthetics. This will help guarantee the best possible outcomes in restoring the level of function to which all our patients are entitled," said AOPA presidentelect Brad Ruhl, vice president of Otto Bock HealthCare, an orthotics and prosthetics manufacturer.
