骨水泥型人工双极股骨头置换治疗高龄不稳定性股骨转子间骨折

目的 探讨应用骨水泥型人工双极股骨头置换治疗高龄不稳定性股骨转子间骨折的可行性及疗效.方法 2004年1月至2008年6月采用股骨转子部重建、骨水泥型人工双极股骨头置换治疗高龄不稳定性股骨转子间骨折46例患者.按改良Evans分型:Ⅲ型19例,Ⅳ型27例.结果 46例患者均顺利完成手术,手术时间50～90(68.00±20.43)min,出血量160～600(210.00±40.26)ml.住院时间16～26(19.30±4.56)d.所有病例获得随访6～39(17.10±4.33)个月.3例患者分别因其他疾病死亡,余43例患者患髋关节Harris评分为70～94(86.70±5.16)分,功能评定结果:优15例,良24例,可3例,差1例.优良率为90.7%(39/43).所有假体在存活期内均未出现脱位、松动、下沉及晚期感染.结论 骨水泥型人工双极股骨头置换术治疗高龄不稳定性股骨转子间骨折具有早期下床活动和术后并发症少等优点,近期随访获得满意的疗效.

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.
