Three cases are presented highlighting varied aspects of labral lesions as a primary or contributing source of mechanical hip pain; including one chronic labral tear associated with old trauma, an acutely entrapped labrum, and a degenerative labral tear associated with osteoarthritis. The diagnosis of labral lesions may be elusive. Arthrography, double-contrast arthrography followed by computerized tomography, and magnetic resonance imaging all have been reported in the assessment of these lesions with variable success. Often, the clinical presentation, including history and physical examination, will yield useful information. A fluoroscopically guided intra-articular injection of the hip is a very useful diagnostic tool for differentiating an intra-articular source of hip symptoms, such as labral lesions, from an extra-articular source. Labral tearing can readily be assessed by arthroscopy and many can be successfully addressed by operative arthroscopy. However, there are many variations in the arthroscopic anatomy of the acetabular labrum.
本文介绍了三个病例，突出了髋臼唇损伤作为机械性髋关节疼痛的主要或促成来源的不同方面；包括一例与陈旧性创伤相关的慢性髋臼唇撕裂、一例急性嵌顿性髋臼唇以及一例与骨关节炎相关的退行性髋臼唇撕裂。髋臼唇损伤的诊断可能难以捉摸。关节造影、双对比关节造影后计算机断层扫描以及磁共振成像在评估这些损伤方面均有报道，但成功率各不相同。通常，临床表现，包括病史和体格检查，会提供有用的信息。在荧光镜引导下进行髋关节腔内注射是一种非常有用的诊断工具，可用于区分髋关节症状的关节内来源，如髋臼唇损伤，与关节外来源。髋臼唇撕裂可通过关节镜轻松评估，许多病例可通过手术关节镜成功治疗。然而，髋臼唇的关节镜解剖结构存在许多变异。
