Little attention has been paid to the various causes preventing or blocking a concentric reduction following traumatic dislocation of the hip without apparent fracture. In a review of fifty-four dislocations, nine required open reduction after either a failed attempt at closed reduction or a non-concentric reduction. The factors preventing closed reduction included the femoral head buttonholed through the capsule and the piriformis muscle displaced across the acetabulum. A concentric anatomical reduction was prevented because of an inverted lumbus or an osteocartilaginous loose body in the acetabulum. Guidelines for diagnosis and treatment are discussed.
对于创伤性髋关节脱位且无明显骨折后妨碍或阻止同心圆复位的各种原因，人们关注较少。在对54例脱位病例的回顾中，9例在闭合复位尝试失败或非同心圆复位后需要切开复位。妨碍闭合复位的因素包括股骨头穿出关节囊以及梨状肌移位至髋臼上方。髋臼内的腰大肌倒置或骨软骨游离体导致了同心圆解剖复位失败。文中讨论了诊断和治疗指南。
