Cemented bipolar hemiprosthesis arthoplasty for 16 senile patients with unstable intertrochanteric fractures

From July 2006 to November 2008, 16 patients with unstable intertrochanteric fractures were treated with cemented bipolar hemiprosthesis arthroplasty, including 5 males and 11 females, at a mean age of 84 years (range, 78-92 years) in the First Affiliated Hospital of Soochow University. Of them, 15 patients were followed with mean time of 14 months. The cemented bipolar hemiprosthesis was purchased from Beijing Montagne. The patients received 5-7 days of antibiotics following arthroplasty in addition to medicine of anticoagulation and analgesia. 1 case died of pulmonary heart disease 10 months after the operation and 3 cases had heterotopic ossification. There was no prosthesis loosening or dislocation. According to Harris hip scores, 3 cases were rated as excellent, 9 good, 3 fair, and 0 poor; the excellent and good rate was 80%. Results show that cemented bipolar hemiprosthesis arthroplasty is effective in treating elderly unstable intertrochanteric fractures, but operation indications require more attention.
