Hip Disarticulate


Hip Disarticulate/Hemipelvectomy/ Transpelvectomy  Prosthetic System

POA’s orginal socket system for hip disarticulate amputations was created by Stan Patterson for Sgt. Josh Olson at the request of Walter Reed Army Medical Center (WRAMC). Olson, who lost his leg as the result of an RPG blast in Iraq, wanted to remain in the Army, but the hip disarticulate prosthetic system he was wearing was rigid, bulky, and so uncomfortable that he found it hard to function in. So in 2004, WRAMC sent Josh to POA to create something that would serve him better. Fourteen-hour days and several prototypes produced a low-profile model that was not visible through Olson’s uniform.  The fit was intimate and secure, preventing the socket movement that beset older versions. Improvements to the socket interface have evolved since then. The following videos shows patients using our most recent design which  incorporates silicone onto the socket itself.

Overview: Prosthetic Fitting Process for HD/HP/TP Amputees

A cast impression is formed and socket is designed from that, providing a precise and comfortable fit. Additional components are added and the resulting prosthesis provides the highest degree of control possible, allowing the wearer to walk with confidence–and sit in comfort!
