STABILIZATION OF THE PROXIMAL FEMUR IN HI P-JOINT REPLACEMENTS PERFORMED BY BY MULLER,M.E. ACETABULAR ROOF METAL SOCKET

Extreme changes of the hip joint often require individual technical su pplements in addition to the endoprosthesis. But the base of success a re procedures using a model of prosthesis and a technique that are mat ured. This is available e.g. with the old M. E. Muller curved stem hip joint prosthesis. In special cases of extreme changes or damage of th e proximal femur we perform in artificial joint-replacements of the hi p or changings of prostheses a special kind of operative treatment. Th is is a combination of the Original-M. E. Muller curved stem endoprost hesis, long or short version of the femoral part, in addition fixated by bone-cement and M. E. Muller's special metal socket - primary indic ated for stabilization of the acetabular roof. The indications for thi s method can be changes of proximal femur and hip-joint, especially dy splasias of pelvis or hip joint, extensive fractures especially in old patients, destructions in polyarthritis, dysplasia of pelvis and coxi tis caused by juvenile chronic arthritis and long time therapy with co rticosteroids, destructions, loosenings and fractures in changing oper ations of hip-endoprostheses. Until today we treated 15 different case s by this method - one case was operated 13 years ago - with good resu lts, prooved by Merle d'Aubigne's score.
