Biomechanics of bipolar hip endoprostheses
WebPellegrino Ferrara. 2016. Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant. Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures. 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 …
