The glenohumeral joint is the most mobile joint in the human skeleton, supported by both active and passive stabilisers. As one of the passive stabilisers, the glenoid labrum has increasingly been recognised to play an important role in stability of the glenohumeral joint, acting to maintain intraarticular pressure, centralise the humeral head and contribute to concavity-compression stability. Several studies have investigated the macro- and micro-anatomical features of the labrum as well as its biomechanical function. However, in order to better understand the role of the labrum and its mechanics, a comprehensive anatomical, functional and biomechanical review of these studies is needed. Therefore, this article reviews the current literature detailing anatomical descriptions of the glenoid labrum, with an emphasis on its function(s) and biomechanics, as well as its interaction with neighbouring structures. The intimate relationship between the labrum and the surrounding structures was found to be important in glenohumeral stability, which owes further investigation into the microanatomy of labrum to better understand this relationship.
盂肱关节是人体骨骼中最灵活的关节，由主动和被动稳定器共同支撑。作为被动稳定器之一，关节盂唇越来越被认为在盂肱关节稳定性中起着重要作用，其作用是维持关节内压、使肱骨头中心复位并有助于凹面压缩稳定性。已有多项研究调查了唇的宏观和微观解剖特征及其生物力学功能。然而，为了更好地了解唇的作用及其力学特性，需要对这些研究进行全面的解剖学、功能和生物力学综述。因此，本文综述了目前详细描述关节盂唇解剖结构的文献，重点介绍其功能和生物力学特性，以及与相邻结构的相互作用。研究发现，唇与周围结构之间的密切关系对盂肱关节的稳定性很重要，这需要进一步研究唇的微观解剖结构，以更好地理解这种关系。
