The purpose of the study is to evaluate residual limb circulation and skin health associated with the use of a novel prosthetic transfemoral socket system. A conventional prosthesis will be compared to the novel transfemoral socket system.

Conventional transfemoral socket designs impose an array of limitations on transfemoral amputee patients. Flexion, extension, and abduction are considerably impaired and end basic functions like sitting are usually uncomfortable or even painful. An alternative socket design that lowers the socket trim-lines and still provides structural support would greatly improve the socket comfort for transfemoral amputees.
