The incidence of dislocation after total hip arthroplasty is significantly higher after revision and in patients with neuromuscular or other complications. To prevent dislocation, 55 patients with multiply revised total hip arthroplasties, unstable hips, and neuromuscular and/or neurologic conditions associated with total hip arthroplasty received implants with the S-ROM constraining acetabular insert. With an average follow up of 30.2 months, 50 patients have not experienced redislocation after insertion. Before S-ROM, our dislocation rate in 176 revision total hip arthroplasties was 19%, but is now 4.5% (P less than .001).
全髋关节置换术后翻修以及患有神经肌肉疾病或其他并发症的患者发生脱位的几率明显更高。为预防脱位，55例接受多次翻修全髋关节置换术、髋关节不稳定以及伴有全髋关节置换术相关神经肌肉和/或神经疾病的患者植入了带有S-ROM限制性髋臼衬垫的假体。平均随访30.2个月后，50例患者植入后未出现再次脱位。在使用S-ROM之前，我们176例全髋关节置换翻修手术的脱位率为19%，而现在为4.5%（P<0.001）。
