Biomechanics of bipolar hip endoprostheses
WebThe paper proposes a mechanical study of the self-centering mechanism of the bipolar prosthesis. This represents the fundamental principle of the bipolar construction, and relays on the offset between the inner and outer center of rotations of the bipolar head. In the paper, the kinematical aspects of the construction were recorded and explained by using … WebThe results obtained are favourable for the bipolar hip endoprosthesis, and they can be related to the biomechanical differences between both types of hip endoprosthesis. Some functional parameters of the hip-joint 3.3 years on average (range 2–8.6 years) after hip arthroplasty are compared with regard to two types of
