Treatment of Unstable Intertrochanteric Fracture with Bipolar Hemiarthroplasty of Hip in Elderly Population: Short-term Results / 고신대학교의과대학학술지

ABSTRACT

OBJECTIVES: The aim of this study is to evaluate the short-term results and complications of treating the intertrochanteric fracture with bipolar hemiarthroplasty (BHA) in elderly population. METHODS: We retrospectively reviewed 31 unstable intertrochanteric fracture patients who were treated with BHA between January 2007 and August 2009 in older populations more than 65 years old. The 6 males and 25 females had a mean age of 79.8 years (range 66-88) and a mean follow-up of 36.3 months (range 24-55). We analyzed the radiological outcomes, functional recovery grade, using Jensen's social function score and Harris hip score (HHS), and complications. RESULTS: The average operation time and blood loss was 148.9 min (range, 110-215 min) and 455.2 mL (range, 200-1200 mL). Mean preoperative and postoperative hemoglobin (Hb) was 10.9 g/dL (range, 8.6-13.4 g/dL) and 10.5 g/dL (range, 5.1-14.1 g/dL) respectively. Average 1.3 pints of blood transfusion was performed. Ambulation with (or without) crutch was possible at mean 6.8 days postoperatively. The stability and alignment indices were adequate in all cases at final follow-up. On clinical results, the average HHS score, was changed from 79.7 points (range, 44-100) preoperatively to 73.0 points (range, 46-92) postoperatively, and the preoperative and postoperative Jensen's score was 1.8 (range, 1-3) and 2.1 (range, 1-4) respectively. CONCLUSIONS: The BHA is an acceptable alternative for unstable intertrochanteric fractures in older population.
