The functional anatomy of the distal radioulnar joint was studied in relation to the whole forearm, using three fresh-frozen, above-elbow amputation specimens. The specimens demonstrate how the proximal and distal radioulnar joints together form a bicondylar joint of special character. The proximal "condyle," the radial head, rotates axially, whereas the distal "condyle," the ulnar head, is fix...

There are approximately 1.6 million lower extremity amputees in the United States. Lower extremity amputees are subject to increased physical demands proportional to their level of amputation. Lower extremity amputees have a 6-fold higher risk of developing radiographic osteoarthritis in the ipsilateral hip and a 2-fold risk of developing radiographic osteoarthritis in contralateral hip when co...

Percutaneous osseointegrated (OI) implants for direct skeletal attachment of upper extremity prosthetics represent an alternative to traditional socket suspension that may yield improved patient function and satisfaction. This is especially true in high-level, transhumeral amputees where prosthetic fitting is challenging and abandonment rates remain high. However, maintaining mechanical integri...

Background: Through knee amputation (TKA) may offer benefits over above (AKA) in patients unsuitable for below amputation. This retrospective analysis compared surgical and rehabilitation outcomes post TKA AKA. Methods: All AKA procedures recorded the Scottish Physiotherapy Amputee Research Group dataset from January 2007 to December 2017 were included analysis. aetiologies, re-amputations bila...

Late Sequelae of Amputation reports an extensive investigation of the late effects of amputation on the general health of the amputee. The subjects in the present series were Finnish war veterans disabled during the 1939-1945 wars and made available for the study while attending a government-sponsored three-week course of rehabilitation at the Kaskisaari Rehabilitation Center in Helsinki. The a...

Limb amputation results in plasticity of connections between the brain and muscles, with the cortical motor representation of the missing limb seemingly shrinking, to the presumed benefit of remaining body parts that have cortical representations adjacent to the now-missing limb. Surprisingly, the corresponding perceptual representation does not suffer a similar fate but instead persists as a p...
