摘要 目的探讨螺旋臼在半髋关节置换术后髋臼翻修术中的应用。方法笔者自2007-01—2013-12采用Zweymüller螺旋臼对30例半髋关节置换术后患者行翻修术。股骨柄假体不松动者只翻修髋臼和更换股骨头,松动者髋臼和股骨柄均翻修。髋臼骨缺损少者采用稍大号的螺旋臼杯,骨缺损大者用同种异体骨颗粒填充缺损,反锉将骨粒压实,选用更大型号的螺旋臼杯。结果 2例感染患者取出假体一期抗生素骨水泥旷置、半年后二期翻修。翻修手术时间平均60(45~70)min,髋臼侧10例未植骨,20例颗粒植骨,均无进行结构性植骨。股骨粗隆部延展截骨12例;保留原股骨柄12例、翻修18例。所有患者均获得随访1.5~7年,平均3年。无下肢深静脉血栓形成及肺栓塞发生,翻修术后双下肢长度差异<2 cm。未出现关节脱位、感染、假体松动。术后Harris评分65~90分,平均80分。结论针对半髋关节置换术后髋臼骨缺损的翻修,螺旋臼是个理想选择。螺旋臼旋入臼壁、避免结构性植骨,操作简单,降低手术难度,临床效果好。
