Comparative Study Clinical Trial[Clinical and radiological results of the thrust plate prosthesis in patients with aseptic necrosis of the femoral head].
In this study, we investigated the results after implantation of the thrust plate prosthesis (TPP) in patients with femoral head necrosis. We intended to answer the question if the femoral neck prosthesis, inaugurated by Huggler and Jacob in Switzerland, which needs a good bone stock for a successful implantation, is a recommendable alternative to other cementless intramedullary fixed prostheses. ⋯ Due to excellent clinical results and nearly identical findings in the survivorship analysis in comparison to cementless stem prostheses, the TPP is also a good alternative implant for total hip arthroplasty in patients with femoral head necrosis. For a successful implantation of the TPP a good bone quality of the proximal femur is necessary. Therefore we cannot recommend the use of a thrust plate prosthesis in patients with femoral head necrosis and simultaneous osteopeny.
