Effect of two types of shoulder prosthesis on the muscle forces using a generic multibody model for different arm motions

open access: yesBioMedical Engineering OnLine, 2022
Background This study aims to analyze the effects of a novel dual-bearing shoulder prosthesis and a conventional reverse shoulder prosthesis on the deltoid and rotator cuff muscle forces for four different arm motions.

Semiconstrained Distal Radioulnar Joint Prosthesis [PDF]

open access: yesJournal of Wrist Surgery, 2013
Distal radioulnar joint (DRUJ) problems can occur as a result of joint instability, abutment, or incongruity. The DRUJ is a weight-bearing joint; the ulnar head is frequently excised either totally or partially, and in some cases it is fused, because of degenerative, rheumatoid, or posttraumatic arthritis.

Adding a toe joint to a prosthesis: walking biomechanics, energetics, and preference of individuals with unilateral below-knee limb loss

open access: yesScientific Reports, 2021
Toe joints play an important functional role in able-bodied walking; however, for prosthesis users, the effect of adding a toe joint to a passive prosthetic foot remains largely unknown. The current study explores the kinematics, kinetics, rate of oxygen

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

open access: yesJournal 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

open access: yesFrontiers 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

open access: yesJournal 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.

An investigation into a locking mechanism designed for a gear-based knee joint prosthesis

open access: yesCogent Engineering, 2020
Background: The knee-locking mechanism in an above-knee prosthesis is crucially important to protect the prosthesis user from sudden falling down due to unexpected disturbance while standing upright.

Finite element analysis of porously punched prosthetic short stem virtually designed for simulative uncemented hip arthroplasty [PDF]

open access: yes, 2017
Background: There is no universal hip implant suitably fills all femoral types, whether prostheses of porous short-stem suitable for Hip Arthroplasty is to be measured scientifically.

Virtual Testing Method of Human Knee Prosthesis

open access: yesInternational Journal of Engineering and Management Sciences, 2019
In the human knee joint, a degenerative wear of the joint can be formed, the common treatment of this disease is the total knee prosthesis geometry replacement and prosthesis implanting, the aim of our research is the study of the human knee joint with ...

Calculation of wear (f.i. wear modulus) in the plastic cup of a hip joint prosthesis [PDF]

open access: yes, 1975
The wear equation is applied to the wear process in a hip joint prosthesis and a wear modulus is defined. The sliding distance, wear modulus, wear volume, wear area, contact angle and the maximum normal stress were calculated and the theoretical ...
