In the setting of chronic instability following total hip arthroplasty, implantation of a constrained acetabular liner may be warranted. We report on a patient who sustained a posterior prosthetic hip dislocation out of the constrained acetabular liner component (Stryker Trident [Kalamazoo, MI]), which had been previously replaced 2 months prior, and underwent a successful closed reduction in the emergency department. At 2-year follow-up, the patient's prosthetic hip has remained stable with no reported issues. To our knowledge, this is the first reported closed reduction of a revised constrained total hip arthroplasty with this implant system, size, and length of follow-up.
在全髋关节置换术后慢性不稳定的情况下，可能有必要植入限制性髋臼衬垫。我们报告了一例患者，其人工髋关节后脱位，脱出先前已在2个月前更换的限制性髋臼衬垫组件（史赛克Trident [密歇根州卡拉马祖]），并在急诊科成功进行了闭合复位。在2年的随访中，患者的人工髋关节一直保持稳定，未报告任何问题。据我们所知，这是首次报道使用该植入系统、尺寸和随访时长的翻修限制性全髋关节置换术进行闭合复位。
