Eine Kniegelenkprothese mit femoralem Hülsenschaft zur Vermeidung einer interprothetischen Femurfraktur

Abstract

Periprosthetic femoral fractures can be a difficult management problem. A certain risk factor occurs in long-stem component concerning biomechanical properties. Bending and torsional strength concentrate on short stem-free region of distal femur. In case of ipsilateral stem knee prosthesis the risk of fracture increase significantly. For prevention of an periprosthetic femoral fracture a total knee arthroplasty was done by using a prosthesis which can be connected rigidly with the hip prosthesis. A cemented femoral tube is put over the distal stem of hip prosthesis. The type of prosthesis, the operative procedure and outcome is presented by reviewed clinical cases.
