[Mechanical changes in the femur induced by a joint prosthesis. Comparative extensometric studies].


This study using electrical extensometry is aimed at comparing the relative deformations of the same fresh femur before and after the successive implantation of the following titanium prostheses: a cement-free prosthesis with metaphyseal endocortical support, a cemented prosthesis with, then without collar, and finally a screwed titanium prosthesis. The 56… (More)
