摘要
观察股骨颈骨折患者行人工全髋关节置换术后股骨偏心距对髋关节功能的影响。方法:选择本院2006年10月至2011年01月间因股骨颈骨折行初次单侧人工全髋关节置换术患者67例,随访时间8~25个月,平均19.3个月。术前统一测量标准,均采用直接外侧入路,使用爱康人工髋臼及股骨柄系统。术后测量双侧髋关节X线片,记录手术前后髋关节活动度及Harris评分,测量股骨偏心距、髋外展肌力臂及双下肢长度,应用SPSS13.0统计软件分析髋关节功能与股骨偏心距的相关性。结果:①股骨偏心距与人工关节术后活动度、Harris评分均存在明显回归相关关系(r=0.403,0.326,P〈0.01)。②下肢跛行情况因股骨偏心距的重建存在显著性差异(X^2=4.13.P〈0.05)。结论:在人工全髋关节置换术中,重建股骨偏心距可改善髋关节的活动功能及减少跛行等并发症。
Objective: To analyze the influence of restoring femoral offset on the femoral neck fractures after total hip arthroplasty (THA). Methods: 67 patients underwent the primary and unilateral total hip arthroplasty were studied from October 2006 to January 2011. The mean follow - up period was 19. 3 months, ranged from 8 to 25 months. A lateral approach was applied in all the procedures. Preoperative and postoperative femoral offset, the ROM of hip and the Harris seores were recorded respectively. Statistical analysis were performed by SPSS13.0 software. Results: Femoral offset was significandy positive related to the ROM of hip ( r = 0. 403 ,P 〈 0. 01 ). Femoral offset was significantly positive related to the Harris scores ( r = 0. 326 ,P 〈 0. 01 ). Restoration of femoral offset influenced the limp ( X^2 = 4. 13 ,P 〈 0. 05 ). Conclusion : restore the offset of femoral can improve hip joint func- tion and reduce complications of claudieatoin in the THA.
