ABSTRACT
Objective To discuss the feasibility and effects of cemented artificial bipolar arthroplasty for senile patients with femoral intertrochanteric instable fractures. Methods From January 2004 to June 2008,46 aged cases with femoral intertrochanteric instable fractures were cured with cemented artificial bipolar arthroplasty. According to improving-classfication of Evans,there were 19 cases with type Ⅲfractures and 27 cases with type Ⅳ fractures. Results All cases were successfully operated. The surgery time was 50-90 (68.00 ±20.43) minutes. Bleeding volume was 160-600 (210.00 ±40.26) ml. The time in hospital was 16-26 (19.30 ± 4.56) days. All cases were retrospectively reviewed for 6-39 (17.10 ± 4.33)months. Three cases died of other diseases, 43 cases were graded by the system of Harris. The Harris scale was 70-94 (86.70 ±5.16) scores,and the choiceness rate was 90.7%(39/43). No dislocation,loosening,subsidence and late infection occurred in all the implants. Conclusions Cemented artificial bipolar arthroplasty has good advantages of reduced laying up period and few complications. The short-term outcome is satisfactory.
