In recent years, numerous studies have examined the relative bone density values of residual limbs following amputation, comparing these against the values of the sound-side limbs or those observed in matched controls. With only rare, individual exceptions, the density values of the amputated limbs are consistently below those of controls.
Does Amputation Level Matter?
The answer to this question depends on who you ask. The observations of Smith et al. suggest that amputation level has no effect on BMD values at either the femoral neck or the total proximal femur.The observations from …

I recently attended a monthly meeting of my local CMSA Chapter.  The sponsor for the meeting was Snell Orthotics and Prosthetics of Little Rock who had invited BiOM to come and speak to us about advanced prosthetics.  John Braddock of BiOM and a patient model showed us an example with the iWalk PowerFoot.  During the presentation, John shared with us that select service members are participating in a program that will allow them to return to active duty.

A project at Vanderbilt University is building  a “smart” prosthesis that gives amputees a more natural gait.  Michael Goldfarb, a professor of mechanical engineering, at Vanderbilt’s Center for Intelligent Mechatronics, has been working for several years with Craig Hutto, who lost his leg in 2005 when he was attacked by a shark. Hutto, who is a lab assistant, has offered valuable input on what works and what doesn’t work for amputees. That has gone a long way towards making the bionic leg comfortable and workable in real-world conditions.
