title: [Static load on human cadaver femora with implanted hip endoprosthesis shafts in various forms].
abstract: The present paper deals with biomechanical investigations applying static pressures to endoprosthetic hip shafts implanted into cadaveric femora with bone cement. The purpose of the investigations was to observe the maximal breakload of the femora or endoprosthesis. We did experiments with 27 femora and implanted 4 different endoprostheses (3 metallic shafts and 1 ceramic shaft). The investigations showed a significant difference between metallic and ceramic shafts in maximal breakload. The metallic shafts showed a favourable load distribution from the prostheses shafts to the femora. That means a higher breakload when the angle between prosthesis-collar and shaft is more than 140 degrees.
