Load Measurement in Bone-Anchored Transfemoral Prostheses: A Pilot Study

This study investigates the load applied to bone-anchored prostheses for individuals with transfemoral amputations. It compares two types of prostheses: a mechanical prosthesis featuring C-Leg and C-Walk foot components, and a microprocessor-controlled prosthesis with Total Knee and Total Shock systems. The research utilizes a transducer to accurately measure loads during various activities, contributing valuable insights into prosthetic performance. The results aim to enhance the design and functionality of prosthetics, improving quality of life for amputees.

  1. Figure 1. Two prostheses used to measure load applied to (a) bone-anchored fixation of individual with transfemoral amputation, including (b) connector, (c) 4-hole standard adapter and designedplate, (d) transducer (model 45E15A, JR3 Inc), (e) knee joint, (g) foot, and (h) footwear. Mechanical prosthesis on left includes (e) C-Leg (Otto Bock), (f) tube adapter (Otto Bock), and (g) C-Walk foot (model 1C40, Otto Bock). Microprocessor-controlled prosthesis on right includes (e) Total Knee (Össur), (f) Total Shock (Össur), and (g) tube adapter (Össur) and Trustep (College Park Inc).
