Abstract:

目的 探讨使用生物型非骨水泥假体治疗髋臼内陷症的近期疗效。方法 2007年6月-2010年5月,对11例12髋髋臼内陷患者行生物型假体全髋关节置换术。男2例,女9例;年龄38~57岁,平均47.3岁。其中继发于类风湿性关节炎7例,创伤4例;病程1~18年,平均8.9年;轻度髋臼内陷6髋,中度髋臼内陷6髋。采用Harris评分标准进行临床疗效评估,摄X线片进行影像学评估。结果 术后第2天X线片示,人工股骨头距Kohler’s线外移(1.42±2.27)mm,较术前股骨头内陷(?5.17±2.04)mm明显改善(P<0.05)。术后1周,患者Harris评分为(85.75±4.73)分,较术前(39.75±5.24)分显著提高(P<0.05)。术后1年X线片示髋臼假体与髋臼内侧壁无透亮线,已骨融合。术后患者获随访2~5年。髋臼假体均无松动移位、脱位或移植骨的吸收。结论 使用生物型非骨水泥假体结合自体骨移植治疗髋臼内陷症,能有效恢复髋臼运动中心的解剖位置,近期临床疗效满意。
