Experimental bench used to test human elbow endoprosthesis

Abstract

In this paper, the 3D virtual model and the prototype of an experimental bench designed and used to test endoprosthesis prototypes for elbow joint in flexion-extension and pronation-supination movements are presented. The experimental tests were carried out on a group of nine healthy subjects and on the corpse prosthetic elbow. Experimental data for flexion-extension movement cycles were acquired using SimiMotion video system. The data files and the flexion-extension angle diagrams are obtained for all the subjects and for the corpse prosthetic elbow. The command programs in C++ for the performance of experimental tests on the bench are elaborated. A comparative experimental study of flexion-extension movement for healthy elbows and for the prosthetic corpse elbow joint fixed on the experimental bench is presented.
