摘要: 目的：探讨使用ZweymÜller双锥面螺旋臼联合PLUS-SL微创柄治疗股骨头坏死继发骨关节炎疗效分析。方法：使用ZweymÜller双锥面螺旋臼假体联合PLUS-SL微创柄治疗股骨头坏死继发骨性关节炎患者50例（58髋）。所有髋臼内衬均采用高交联聚乙烯防脱位内衬，陶瓷球头，随访10～32个月。结果：50例患者术后疼痛基本消失，双下肢长度差异平均（1.2±0.51）cm，术后Harris评分较术前显著增高（P<0.01）。结论：ZweymÜller双锥面螺旋臼联合PLUS-SL微创柄治疗股骨头坏死继发骨关节炎可以达到良好的恢复关节功能的临床疗效。Abstract: Objective: To investigate the curative effects of double-sided cone spiral mortar Zweymüller combined with PLUS-SL micro-invasive handle in the treatment of femoral head necrosis complicated with secondary osteoarthritis.Methods: Fifty-eight hips(50 cases) with femoral head necrosis complicated with secondary osteoarthritis were treated with double-sided cone spiral mortar Zweymüller combined with PLUS-SL micro-invasive handle.All acetabulums were lined with high cross linking polyethylene dislocation and ceramic ball head.All patients were followed up for 10 to 32 months.Results: The postoperative pain disappeared in all patients.The difference of the lengths of both legs was(1.2±0.51) cm,the postoperative Harris score was significantly higher than that of before operation(P<0.01).Conclusions: The treatment of femoral head necrosis complicated with secondary osteoarthritis with double-sided cone spiral mortar Zweymüller combined with PLUS-SL micro-invasive handle can improve the recovery of the joint function.
