[Outcome of management of femoral neck fractures with cemented bipolar endoprostheses].

In our hospital 334 patients were treated with a bipolar prosthesis for medial femoral neck fracture in the years 1990 and 1991. After an average of 54 months (minimum 48 months) informations about function could be obtained by examination and x-ray from 19 patients (5.7%), from 42 patients (12.6%) a questionnaire was analyzed. No function of the hip was described as poor, 2/3 of the patients had no pain, nearly 50% walked without crutches or other tools. No protrusio acetabuli or acetabular erosion was seen. Together with further follow-up examinations from another 230 patients out of 1365 patients treated with a bipolar prosthesis up to now, these results support the statement that bipolar prostheses play an important role in treatment of medial femoral neck fractures in the elderly.
