[Torsion forces of the proximal femur following implantation of a hip prostheses].
Growing interest in hip endoprosthesis is inducing a lot of ideas for formgiving, without having cleared the adequate strength to the proximale femur. To know more about these forces, we made computerized tension-analyses of some different types of prosthesis in a normed artificial femur. Measurement of press- and tensile tensions on one hand and the torsion-tensions on the other hand showed some enhanced forces which might be the reason for slackening of hip endoprosthesis.
