To highlight a case of recurrent atraumatic anterior hip dislocation management using a dual mobility prothesis.
The stability of the patient's hip was assessed using X-ray and MRI scans. Upon the third spontaneous anterior dislocation it was decided with the patient's consent to undergo a total hip replacement. A piriformis sparing anterior approach was use with the insertion of a dual mobility bearing. This consisted of an uncemented porous titanium cup articulating with a 28 mm head in a 42 mm mobile polyethylene liner.
Mobilising pain free at 6 weeks post operation with no further dislocations at 6 months follow up.
Dual mobility hip replacements was used successfully in our patient with recurrent atraumatic anterior hip dislocation.
重点介绍一例使用双动假体治疗复发性非创伤性前髋关节脱位的病例。
通过X线和磁共振成像扫描评估患者髋关节的稳定性。在第三次自发性前脱位后，经患者同意决定进行全髋关节置换术。采用保留梨状肌的前入路并植入双动轴承。该假体由一个非骨水泥型多孔钛杯与一个42毫米活动聚乙烯内衬中的28毫米股骨头相连接组成。
术后6周可无痛活动，6个月随访时未再发生脱位。
双动髋关节置换术成功应用于我们这位复发性非创伤性前髋关节脱位的患者。
