摘 要: | 背景:髓心减压及钽棒置入治疗早期股骨头坏死的手术方法,尤其适合于股骨头坏死SteinbergⅠ期和Ⅱ期,既可以解决疼痛又可以防治股骨头的塌陷延缓坏死的进展,是一种值得尝试的新方法。 目的:探讨多孔钽棒置入治疗股骨头坏死的适应症及其临床疗效。方法:纳入股骨头坏死16例18髋,根据Steinberg分期:Ⅰ期5髋,Ⅱ期12髋,Ⅲ期A 1髋。采用侧方小切口入路,行髓心减压及多孔坦棒置入。置入后6周内禁止负重,6~10周部分负重,逐步过渡至完全负重。采用Harris评分系统评估患者置入后髋关节功能改善情况;置入后24 h、1,3,6,12个月摄正侧位X射线平片,观察股骨头修复情况及有无坏死进展。结果与结论:16例18髋获得随访,随访时间7~13个月。置入后末次随访进行疗效评估,优:11例12髋,良:4例5髋,可:1例1髋。患者Harris评分由置入前49~83分,平均(65.3±8.6)分,提高至置入后75~97分,平均(88.2±9.3)分,治疗前后比较差异有显著性意义(P < 0.05)。随访摄片髋关节影像学表现稳定,股骨头无坏死进展。提示,多孔钽棒假体置入治疗股骨头坏死疗效确切,尤其是对于SteinbergⅠ期,Ⅱ期及塌陷较小的 ⅢA期股骨头坏死的患者。
