摘要 目的评估钽棒治疗围塌陷期股骨头坏死的临床疗效,分析股骨头生存率的影响因素。方法回顾性分析30例30髋围塌陷期股骨头坏死接受钽棒植入术患者的临床资料,其中国际骨循环协会(ARCO)ⅡA期2髋,ⅡB期12髋,ⅡC期11髋,ⅢA期5髋。以股骨头塌陷>4 mm作为研究终点,通过VAS评分评估关节疼痛程度,根据Harris评分评估髋关节功能;通过分析坏死部位及坏死范围对钽棒植入术后股骨头生存率的影响,探讨钽棒植入的适应证。结果术前至术后末次随访,VAS评分从(4.37±1.69)分下降至(1.13±0.97)分,差异有统计学意义(P<0.01);整体Harris评分从(84.91±6.95)分提高至(93.89±2.88)分,差异有统计学意义(P<0.05)。当坏死范围超过67%时,患髋生存率为25.0%;当正位分型为C2型时,其生存率只有22.2%。结论钽棒植入术是治疗围塌陷期股骨头坏死的有效方法。正位分型中的C2型或改良坏死指数超过67%建议采用其他治疗方法。
