Femoroacetabular impingement is a motion-based concept of conflict that occurs secondary to morphologic abnormalities of the proximal femur and/or acetabulum. Creating impingement-free motion through restoration of normal morphology serves as the goal of joint-preserving procedures. We retrospectively reviewed the short-term functional and radiographic outcomes of 46 patients (48 hips) with femoroacetabular impingement treated with a surgical dislocation and restoration of offset. The average Merle D'Aubigné-Postel score improved from a preoperative of 13 (range, 7-16 +/- 1.7) to a postoperative score of 16.8 (range, 12-18 +/- 1.3). Creating impingement-free motion via a surgical dislocation improves symptoms in patients with limited radiographic signs of arthritis who are experiencing impingement-related hip pain.
股骨髋臼撞击症是一种基于运动的冲突概念，继发于股骨近端和/或髋臼的形态异常。通过恢复正常形态来创造无撞击的运动是保关节手术的目标。我们回顾性分析了46例（48髋）接受手术脱位和恢复偏移治疗的股骨髋臼撞击症患者的短期功能和影像学结果。Merle D'Aubigné-Postel平均评分从术前的13分（范围7 - 16分，±1.7）提高到术后的16.8分（范围12 - 18分，±1.3）。通过手术脱位创造无撞击的运动可改善有有限关节炎影像学表现且正经历与撞击相关髋关节疼痛患者的症状。
