EXPERIENCE WITH BIPOLAR HEMIARTHROPLASTY FOR FRACTURES OF THE FEMORAL-NECK

In our hospital 334 patients were treated with a bipolar prosthesis fo r medial femoral neck fracture in the years 1990 and 1991. After an av erage of 54 months (minimum 48 months) informations about function cou ld he obtained by examination and x-ray from 19 patients (5,7%), from 42 patients (12,6%) a questionnaire was analyzed. No function of the h ip was described as poor, 2/3 of the patients had no pain, nearly 50% walked without crutches or other tools. No protrusio acetabuli or acet abular 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.
