盂唇撕裂通常为特定创伤的结果，例如跌倒时外展的手臂着地。撕裂也可因慢性抬臂超过头的动作引起，如发生在投掷动作。关节盂盂唇撕裂可引起活动时疼痛。治疗为理疗，有时需手术。
肩关节（与髋关节或肘关节不同）本身结构不稳定，它就像球座上的高尔夫球。为使结构更稳固，关节盂（解剖上为一个很浅的窝）通过盂唇加深，盂唇是一个围绕在关节盂边缘、坚韧的纤维软骨组织。竞技时尤其是投掷运动时，或摔倒在伸展的上臂上引起钝挫伤时，这些结构易发生撕裂。
盂唇撕裂的症状和体征
关节盂唇撕裂会导致活动时的肩部深处疼痛，尤其是在投掷棒球时。病人疼痛同时可伴有一个痛苦的咔哒或噔噔的感觉 ，和肩部捕获感。
盂唇撕裂的诊断
通常要行对比增强MRI检查
初诊时应对肩部和颈部做全面的体格检查，但经常需要向专家咨询，因为更先进的诊断测试（例如，对比增强MRI）往往是明确识别病变的唯一途径。从前到后的上盂唇撕裂 (SLAP) 和 Bankart 撕裂（前）是最常见的盂唇撕裂类型。
盂唇撕裂的治疗
物理疗法
有时需手术治疗
物理疗法是初始治疗方法。如理疗后症状没有改善，且已经MRI明确诊断，手术清创或修复则为治疗选择。手术通常需要用关节镜。
