Bipolar Hemiarthroplasty with Cementless Femoral Stem for Unstable Intertrochanteric Fractures / 대한정형외과학회잡지

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the usefulness of bipolar hemiarthroplasty using a cementless femoral stem for treating unstable intertrochanteric fractures in elderly patients. MATERIALS AND METHODS: This study included 41 hips of 41 patients who were followed up for over 2 years after bipolar hemiarthroplasty using cementless femoral stem between October 2006 and November 2008. The mean follow-up period was 33 months (24-42 months). RESULTS: At the last follow-up, the mean Harris hip score was 81.3 points. All stems were stable without significant changes in alignment or progressive subsidence. There were no cases of leg length discrepancy over 5 mm. There were 3 cases of wire fixation breakage and 1 case of posterior hip dislocation. CONCLUSION: The short-term results over 2 years of clinical and radiological evaluation of cementless bipolar hemiarthroplasty and wire fixation were satisfactory in elderly patients with unstable intertrochanteric fracture.
