[Tumour prosthesis in the treatment of metastases, loosening of prosthesis and fractures at the proximal femur (author's transl)].

19 patients were treated via a tumour prosthesis in the hip joint region. The indication resulted from osteolyses, loosening of prosthesis and subtrochanteric fractures in aged patients involving risk factors. The results show that application of a tumour prosthesis is a suitable method for bridging over major defects in the proximal femur to achieve early mobilisation of the patients associated with full load of the extremity on which the operation had been performed.
