Abstract

It is apparent that socket fit is the most common source of dissatisfaction in amputees and part of a growing medical and socioeconomic problem. Even the most up to date trans-tibial socket designs are not capable of coping with the issue of continuous stump volume change that is apparent within a day, week, month or season of socket use. Intelligent sockets integrating variable volume (VVSS) with elevated vacuum (EV) systems hold that promise but have yet to reach completion in feasibility studies. This is mainly due to delays in the relevant technological maturity, cost and poor assessment methodologies. These challenges can be overcome by current advantages in dynamic radiography imaging. These advantages are presented with an example of a novel socket design as: a) solutions to problems of direct socket-stump motion measurement, and b) as tools for calibrating socket control hardware and computer aided socket design. Imaging can therefore be integrated as part of an expert clinical system for imaging-driven computer-aided socket design and evaluation (cost-labor effective).
