包括生物化学、遗传和后天异常在内的多种因素可能导致髋关节骨关节炎。虽然影响发育不良髋关节的退行性过程的病理机制已被充分理解，但特发性骨关节炎的确切发病机制尚未确定。根据临床经验，600多例髋关节手术脱位，允许原位检查损伤模式及其起源的动态证据，我们提出股骨髋臼撞击作为大多数非发育不良髋关节早期骨关节炎发展的机制。该概念更侧重于运动，而不是髋关节的轴向载荷。不同的临床、影像学和术中参数可用于确认该实体的诊断并及时给予治疗。股骨髋臼撞击症的手术治疗重点是改善髋关节活动间隙和减轻股骨对髋臼边缘的抵靠。建议早期手术干预治疗股骨髋臼撞击，除了缓解症状外，还可以减缓这组年轻患者退行性过程的进展。
A multitude of factors including biochemical, genetic, and acquired abnormalities may contribute to osteoarthritis of the hip. Although the pathomechanism of the degenerative process affecting the dysplastic hip is well understood, the exact pathogenesis for idiopathic osteoarthritis has not been established. Based on clinical experience, with more than 600 surgical dislocations of the hip, allowing in situ inspection of the damage pattern and the dynamic proof of its origin, we propose femoroacetabular impingement as a mechanism for the development of early osteoarthritis for most nondysplastic hips. The concept focuses more on motion than on axial loading of the hip. Distinct clinical, radiographic, and intraoperative parameters can be used to confirm the diagnosis of this entity with timely delivery of treatment. Surgical treatment of femoroacetabular impingement focuses on improving the clearance for hip motion and alleviation of femoral abutment against the acetabular rim. It is proposed that early surgical intervention for treatment of femoroacetabular impingement, besides providing relief of symptoms, may decelerate the progression of the degenerative process for this group of young patients.
