![عکس صفحه اول مقاله: Femoroacetabular Cup Impingement After Resurfacing Arthroplasty of the Hip Femoroacetabular Cup Impingement After Resurfacing Arthroplasty of the Hip](/preview/png/4062075.png)
Femoroacetabular cup impingement (FACI), defined as the presence of a bony spur or indentation at the femoral neck corresponding to the abutment site of metallic cup, was observed in 9 (11%) of the 84 hips with contemporary resurfacing arthroplasty of the hip. All FACIs occurred in men after a mean of 14 months (range, 8-24 months) postoperatively. Five patients had persistent groin pain if the hip was moved into flexion, abduction, and external rotation. One patient sustained a late-onset fracture through the femoral neck already weakened by postoperative change of osteonecrosis. Mean postoperative Harris hip score in the FACI group was poorer than that in the non-FACI group (P = .003). Multiple logistic regression analysis showed a significant association of FACI with a low acetabular cup inclination (odds ratio, 1.42; 95% confidence interval, 1.01-1.99; P = .046) and a high cup uncoverage ratio (odds ratio, 1.36; 95% confidence interval, 1.01-1.84; P = .045).
