Abstract:
PURPOSE: The purpose of this study was to evaluate clinicoradiological outcomes after cementless bipolar hemiarthroplasty in elderly patients with femoral neck fractures. MATERIALS AND METHODS: Eighty hips-all in patients greater than 70 years of age-were followed for more than 2 years after undergoing cementless bipolar hemiarthroplasty with a tapered cementless stem (Lima SPH-C2(R)). The mean age was 76 years, and the mean follow-up period was 37 months. The Harris hip score and postoperative hip pain were analyzed clinically. The radiological results were assessed using various radiological indices. RESULTS: At last follow-up, the mean Harris hip score was 80.2 points. There was one case of significant hip pain. Fifty-five cases (68.7%) showed no decrease in ambulation capacity postoperatively. Radiologically, there were 47 cases (58.7%) of bone ingrowth and 33 cases (41.3%) of stable fibrous fixation. There were no cases of osteolysis, and 30 cases (37.5%) exhibited new bone formation around the stem. All stems were stable without significant alignment change or progressive subsidence. CONCLUSION: Short-term outcomes proved to be satisfactory in elderly patients undergoing cementless bipolar hemiarthroplasty for femoral neck fractures.
