在300例全髋关节置换术中，9例（3%）脱位。精确测量髋臼杯的方向;前脱位与髋臼组件前倾增加有关。髋臼杯方向角与后脱位无明显相关性。前倾角为15 ± 10 °时髋臼杯方向的脱位率。10.degree.和40 ±的横向开口。10.degree.在安全范围外脱位率为6.1%。记录的其他因素包括术后时间（前30天风险最大）和手术史（既往手术的髋关节风险更大）。
In a series of 300 total hip replacements, 9 (3%) dislocated. Precise measurements of the orientation of the acetabular cup were made; anterior dislocations were associated with increased acetabular-component anteversion. There was no significant correlation between cup-orientation angle and posterior dislocation. The dislocation rate for cup orientation with anteversion of 15 .+-. 10.degree. and lateral opening of 40 .+-. 10.degree. was 1.5%, while outside this safe range the dislocation rate was 6.1%. Other factors that were documented include time after surgery (with the greatest risk in the first 30 days) and surgical history (with a greater risk in hips that have had prior surgery).
