Femoroacetabular impingement (FAI), a recently described hip condition in adolescents and young adults, typically manifests as activity-related hip pain. Characteristic physical findings include limited passive internal rotation of the affected hip and a positive impingement sign. Diagnostic imaging may reveal cam and/or pincer lesions, and associated intra-articular pathology (eg, labral tear, chondral damage) is common. When nonoperative treatment fails to adequately alleviate symptoms, surgery may be warranted. Both open and arthroscopic techniques have been effective. As our understanding of FAI continues to evolve, sex-based differences in incidence, presentation, and outcomes for patients with FAI have become apparent. Understanding the different ways in which males and females may present with FAI and then changing clinical practice patterns to accommodate these sexual dimorphisms will likely result in improved outcomes for each patient with symptomatic FAI.
股骨髋臼撞击症（FAI）是一种最近才被描述的发生于青少年和年轻成年人的髋关节疾病，通常表现为与活动相关的髋关节疼痛。典型的体格检查发现包括患侧髋关节被动内旋受限和撞击征阳性。诊断性影像学检查可能显示凸轮和/或钳夹样病变，并且常见相关的关节内病变（如盂唇撕裂、软骨损伤）。当非手术治疗不能充分缓解症状时，可能需要手术治疗。开放手术和关节镜技术都已证实有效。随着我们对FAI的认识不断发展，FAI患者在发病率、临床表现和治疗结果方面的性别差异已变得明显。了解男性和女性可能出现FAI的不同方式，然后改变临床实践模式以适应这些性别差异，可能会改善每位有症状FAI患者的治疗结果。
