Cemented bipolar hemiarthroplasty with a cerclage cable technique for unstable intertrochanteric hip fractures in elderly patients.

Abstract

The purpose of this study is to evaluate the clinical and radiological outcomes of cemented bipolar arthroplasty as a primary treatment for unstable intertrochanteric fracture in the elderly patients. Twenty hips with unstable intertrochanteric fractures were followed for more than 2 years after cemented bipolar hemiarthroplasty. The mean age was 69 years, and the mean follow-up period was 30.5 months. We evaluated the results by Harris hip score, complications, and radiologic findings. At the last follow-up, the mean Harris hip score was 83.3 points. Radiologically, there was no case of osteolysis. All stems were stable without significant changes in alignment or progressive subsidence. Bipolar hemiarthroplasty with calcar reconstruction is a good option for unstable intertrochanteric fractures in elderly patients with severe osteoporosis with strict indication selection. Longer-term studies with larger numbers of patients are required to address the issues of late complications.
