Abstract

The glenohumeral ligaments, particularly the inferior one, are the major passive stabilizers of the joint, and the labrum functions as a site of ligamentous attachment. The strong union between the collagen fibers of the glenohumeral ligaments and the glenoid labrum is more resistant to injury than the union between the glenoid rim and the labrum. Labral tears associated with glenohumeral instability are therefore usually secondary to avulsion rather than impaction. This article reviews the normal MR imaging anatomy, variants and pitfalls of the glenohumeral ligaments, and the basic biomechanics of the glenohumeral ligaments. Examples of injuries involving these structures are provided.

摘要

盂肱韧带，尤其是下盂肱韧带，是该关节主要的被动稳定结构，而盂唇起着韧带附着点的作用。盂肱韧带的胶原纤维与盂唇之间的牢固结合比关节盂边缘与盂唇之间的结合更能抵抗损伤。因此，与盂肱关节不稳相关的盂唇撕裂通常继发于撕脱而非撞击。本文回顾了盂肱韧带的正常磁共振成像解剖、变异及陷阱，以及盂肱韧带的基本生物力学。文中还提供了涉及这些结构损伤的实例。
