Development of Subischial Prosthetic Sockets with Vacuum-Assisted Suspension for Highly Active Persons with Transfemoral Amputations

Abstract

The purpose of this project was to develop a highly flexible sub-ischial prosthetic socket with assisted-vacuum suspension for highly active persons with transfemoral amputation. The Specific Aims were to: A1. Develop a highly flexible socket with sub-ischial trim lines; A2.Develop durable liners and sealing sleeves; A3. Develop/identify an appropriate vacuum pump;A4. Evaluate system performance with military amputees; and A5. Develop education materials. We completed all tasks, including supplemental tasks related to building and testing the hybrid vacuum pump, year 6 observational study to assess effect of interface components on weight bearing, and dissemination of the technique to certified prosthetists via hands-on workshops.
