Total hip arthroplasty is a successful operation for the treatment of hip pain. One of the common complications of hip arthroplasty is dislocation. While reduction of standard prosthetic dislocations is highly successful, new prostheses add the potential for new complications.
We present the case of a patient who experienced intraprosthetic dislocation of an anatomic dual-mobility total hip prosthesis after a closed hip reduction and include the prereduction and postreduction radiographic findings.
Emergency department physicians should be aware of intraprosthetic dislocation. This complication can be easily missed because the metal/ceramic femoral head appears to be reduced in the acetabulum.
全髋关节置换术是治疗髋关节疼痛的一种成功手术。髋关节置换术的常见并发症之一是脱位。虽然标准假体脱位的复位成功率很高，但新型假体增加了出现新并发症的可能性。
我们报告了一例患者，其在髋关节闭合复位后发生了解剖型双动全髋关节假体的假体内部脱位，并包括复位前后的影像学表现。
急诊科医生应意识到假体内部脱位。这种并发症很容易被漏诊，因为金属/陶瓷股骨头在髋臼内看似已复位。
