Salvage Operation for a Failed Total Wrist Prosthesis and Darrach Procedure by Total Wrist Revision and Distal Radioulnar Joint Arthroplasty

Journal of Hand Surgery Global Online, 2020
An unstable distal ulnar stump after Darrach resection, alongside pathology of the radiocarpal joint, is difficult to manage without fusion of at least one joint. Currently, no standard 2-in-1 arthroplasty is available.

Biomechanical Impacts of Toe Joint With Transfemoral Amputee Using a Powered Knee-Ankle Prosthesis

Frontiers in Neurorobotics, 2022
Transfemoral amputees are currently forced to utilize energetically passive prostheses that provide little to no propulsive work. Among the several joints and muscles required for healthy walking, the ones most vital for push-off assistance include the ...

Effects of prosthetic design parameters on running performance of a unilateral transfemoral amputee

Journal of Biomechanical Science and Engineering, 2021
Carbon fiber running-specific prostheses (RSPs) are widely used among lower-limb amputee runners. However, which prosthesis provides the best performance for runners remains unknown.

Development of the Transfemoral Prosthesis for Swimming Focused on Ankle Joint Motion

Journal of Biomechanical Science and Engineering, 2013
The objective of this study was to develop a prototype of transfemoral prosthesis for swimming focused on the ankle joint motion. This prosthesis has (i) an ankle joint which provides appropriate foot motion, (ii) the capability of walking on land by the

Automated Forearm Prosthesis Controlling Using Fiber Bragg Grating Sensor [PDF]

Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2023
This paper describes the automation of a forearm prosthesis using the signal collected by a Fiber Bragg Grating (FBG) sensor. The FBG sensor is applied to one subject's forearm to measure the deformation as a result of the index and middle fingers when ...
