摘要
[目的]通过手术前后对髋臼旋转中心的X线测量,探讨髋臼旋转中心的变化对髋关节平衡稳定性的影响。[方法]追溯调查近年本院收治120例155髋,均为首次行全髋关节置换术患者,对比术前术后双髋关节正位X线片,比较术后髋臼假体的旋转中心(HJC1)与解剖髋臼旋转中心(HJC0)的符合率。[结果]旋转中心恢复者98髋(63.23%)(A组),未恢复者57髋(36.77%)(B组);A、B两组中因人工髋关节松动、脱位、髋部痛等行髋关节假体翻修术分别为6髋(6.12%)、17髋(29.82%)。[结论]髋臼旋转中心的恢复对人工髋关节置换术后的关节稳定性有直接影响。
[ Objective]To explore the effect of hip joint center on the stability of hip joint, the radiographic measurements were compared between preoperation and postoperation. [ Method] A total of 155 hips from 120 patients with primary total hip replacement from resent years were studied,the hip joint center difference through radiographic measurements between preoperation and postoperation were compared. [ Result]The coincident rate and the incoincident rate were 63.23% （group A,98 hips ） and 36.77% （ group B, 57 hips ） respectively. For loose, dislocation or low back pain, the rate of revision in group A and group B were 6.12% and 29.82% respectively. [ Conclusion ] The comeback of hip joint center was essential for stability of hip joint.
