The most statistically significant risk factors for hip dislocations following total hip arthroplasty include prior hip surgery, trochanteric nonunion, and posterior surgical approach. Reoperation is required in only about one third of those patients who sustained dislocations. The most reliable surgical procedure is reorientation of the retroverted acetabular component. Care should be exercised to define the precise cause of the instability to plan the surgery that best addresses this particular problem.
全髋关节置换术后发生髋关节脱位的最具统计学意义的风险因素包括既往髋关节手术、转子不愈合和后入路手术。仅约三分之一发生脱位的患者需要再次手术。最可靠的手术方法是重新调整髋臼假体后倾的方向。应谨慎确定不稳定的确切原因，以便规划最能解决这一特定问题的手术。
