摘要
目的探讨股骨近端髓内钉治疗股骨转子间骨折术后内固定失败的翻修策略。方法选取2010年1月至2018年6月因股骨转子间骨折行股骨近端髓内钉内固定治疗后内固定失败的患者23例,采用关节置换或更换内固定+断端植骨进行治疗。评估手术前后Harris评分及SF-12生存质量评分。结果所有病例均顺利完成手术并出院。平均随访时间22.3个月。末次Harris评分[(86.6±5.7)分]相比术前[(34.2±15.1)分]差异有统计学意义(P <0.01);末次SF-12评分[生理总得分(48.6±2.1)分,心理总得分(46.5±2.9)分]相比术前[生理总得分(26.5±2.8)分,心理总得分(28.7±2.7)分]差异有统计学意义(P <0.01)。随访期间2例患者死亡,所有病例无假体松动及内固定移位并发症。结论股骨近端髓内钉治疗股骨转子间骨折术后内固定失败的翻修应根据具体情况来选择不同治疗方案,患者年龄、身体状况、骨折类型、内固定失败类型均为考虑因素。
Objective Evaluation of the revision for failed proximal femur intramedullary nail of intertro-chanteric fracture. Methods A retrospective analysis was carried out in 23 intertrochanteric fracture patients of failed proximal femur intramedullary nail in our department from January 2010 to June 2018. Arthroplasty or replace internal fixation + bone graft were treated for revision. Harris hip score and SF-12 score were evaluated before and aftersurgery. Results All cases finished surgery successfully and the patients had already discharged.The follow-up time was 22.3 months in average. The mean value of the last Harris hip score(86.6 ± 5.7),mean value of the last SF-12 score[physical component summary(48.6 ± 2.1),mental component summary(46.5 ±2.9)]were significant higher than pre-operation[Harris hip score(34.2 ± 15.1),P < 0.01;physical component summary(26.5 ± 2.8),mental component summary(28.7 ± 2.7),P < 0.001]. 2 cases died during follow-up. All cases didn′t show prosthesis loosening and internal fixation migration. Conclusions The treatment of failed proxi-mal femur intramedullary nail depend on specific condition. The age,physical conditions,type of fracture and type of failed should be taken into considerations.
