锁定加压钢板内固定治疗股骨粗隆间骨折疗效分析

The efficacy of internal fixation of locking compression plate in the treatment of intertrochanteric femur fracture

目的探讨锁定加压钢板(LCP)在治疗股骨粗隆间骨折中的临床疗效。方法2005年2月～2009年5月,对42例42髋股骨粗隆间骨折采用闭合复位,AO股骨近端锁定加压钢板内固定治疗。按AO/ASIF分类:A1型24例,A2型12例,A3型6例。术后无需外固定。结果所有患者均安全完成手术,随访5～56个月,平均21.5个月;骨折均获得愈合,骨折愈合时间12～24周,平均16.5周。无内固定失败。临床结果按Sanders评估标准,优34例,良6例,可1例,差1例,优良率95.2%。结论股骨近端锁定加压钢板具有操作简便、固定可靠、组织损伤小等优点,是治疗股骨粗隆间骨折的理想方法之一。

Objective To evaluate the clinical efficacy of locking compression plate （LCP） in the treatment of intertrochanteric femur fracture. Methods From February 2005 to May 2009, 42 patients with 42 intertrochanteric femur fractures underwent close reduction and internal fixation of LCP at the proximal femur. According to AO/ASIF classification, the fracture was of type A1 （n=24）, type A2 （n=12）, and type A3 （n=6）. External fixation was not needed after surgery. Results All surgeries were completed safely. All patients were followed up for 5 to 56 months, with 21.5 months on average. All fractures healed 12 to 24 weeks after surgery, with 16.5 weeks on average. No failure of internal fixation occurred. According to Sanders post-trauma function assessment, the results were excellent （n=34）, good （n=6）, fair （n=l） and poor （n=1）. The ratio of excellent and good results was 95.2% （40/42）. Conclusions In the treatment of intertrochanteric femur fracture, LCP at the proximal femur has the advantage of simple operation, solid fixation and less damage to the tissues.
