[Surgical treatment possibilities in aseptic and septic loosening of endoprostheses of the hip].

There is a permanent increase of replacement of endoprosthesis of the hip. The improvement of operation procedure and the application of spongious bone make it possible to reconstruct extreme defects of bone tissue of acetabulum and femur. The bacterial infection of the supporting tissue is the most serious complication in endoprosthesis. Even in early diagnosis and consequent therapy the infection often is not curable until endoprosthesis is removed. The resulting condition, which is similar to that seen after Girdlestone's operation, will mostly ensure an improved functional capacity of the hip joint.
