We present 2 cases of cam/pincer combined femoroacetabular impingement treated arthroscopically with labral debridement, acetabuloplasty, and femoral head recontouring. In both cases there was essentially no evidence of osteoarthritis of the hip. However, in both cases raised exostoses were evident on the anterolateral femoral neck in the region that commonly comes into contact with the acetabular rim. On the basis of 3-dimensional dynamic reconstructions, we surmise that these exostoses are a direct result of linear contact between the femoral neck and acetabular rim. We recommend that the presence of these exostoses be carefully noted by the arthroscopic hip surgeon and that they be a geographic marker of the zone of contact between the head-neck junction and the acetabular rim and a guide for the area of head osteochondroplasty in combination with appropriate treatment of the acetabular rim.
我们介绍了 2 例经关节镜治疗的凸轮/钳夹型股骨髋臼撞击综合征患者，采用了髋臼唇修整、髋臼成形术和股骨头重塑。在这 2 例患者中，髋关节骨关节炎的证据基本不存在。然而，在这 2 例患者中，在前侧股骨颈区域都可见到明显的隆起性骨赘，该区域通常与髋臼缘接触。基于 3 维动态重建，我们推测这些骨赘是股骨颈和髋臼缘线性接触的直接结果。我们建议关节镜髋关节外科医生仔细注意这些骨赘的存在，并将其作为股骨头颈交界处和髋臼缘接触区域的地理标志，以及头骨骨软骨切除术的区域指南，同时结合髋臼缘的适当治疗。
