This study reports the results and complications from treating recurrent hip dislocations with a constrained liner (CL) after total hip arthroplasty (THA). Forty patients who had a CL inserted as a secondary prophylactic treatment were retrospectively reviewed after a median observation period of 27 months (range 7-77 months). During the observation period five patients had to be revised: one for deep infection and four on account of re-dislocations. Our results indicate that patients with recurrent THA dislocations can be treated with a CL and has a satisfactory low complication rate and a relatively low risk of re-dislocation.
本研究报告了全髋关节置换术（THA）后使用限制性衬垫（CL）治疗复发性髋关节脱位的结果及并发症。对40例行CL植入作为二次预防性治疗的患者进行回顾性分析，中位观察期为27个月（范围7 - 77个月）。观察期内，5例患者需进行翻修手术：1例因深部感染，4例因再次脱位。我们的结果表明，复发性THA脱位患者可采用CL治疗，并发症发生率低，再次脱位风险相对较低，效果令人满意。
