The sublabral foramen is considered to be a clinically asymptomatic, isolated variant of the anterior-superior capsulo-labral-complex. It may be observed during shoulder arthroscopy and may implicate problems in differential diagnosis of traumatic lesions. In an anatomic study on 89 macroscopically healthy shoulder specimens the age distribution and the incidence in relation to the varying shape of the glenoid as feasible factors of influence for a sublabral foramen (SF) were analyzed in order to elucidate the unknown pathogenesis of SF. In addition histologic sections of three SF samples were obtained. Mean age of the specimens with a sublabral foramen [n=20; 69 (37-84) years] was significantly higher (p=0.04) compared to samples without a sublabral foramen [n=69; 59 (18-94) years]. An increased incidence of a sublabral foramen in relation to a distinct shape of the glenoid could not be established although a prevalence of a glenoid with anterior notch was observed. The results indicate an age-related development of the sublabral foramen,thus in younger patients with an anterior-superior capsulolabral displacement local signs of trauma and involvement of the biceps anchor should be controlled before definitive diagnosis.
盂唇下孔被认为是前上盂唇复合体的一种临床上无症状的孤立变异。它可能在肩关节镜检查时被观察到，并且可能在创伤性病变的鉴别诊断中引发问题。在一项对89个宏观上健康的肩部标本的解剖学研究中，分析了年龄分布以及与不同形状的关节盂相关的发生率，将其作为盂唇下孔（SF）可能的影响因素，以阐明SF未知的发病机制。此外，还获取了三个SF样本的组织学切片。有盂唇下孔的标本的平均年龄[n = 20；69（37 - 84）岁]与没有盂唇下孔的样本[n = 69；59（18 - 94）岁]相比显著更高（p = 0.04）。尽管观察到关节盂有前切迹的患病率，但未发现盂唇下孔的发生率与关节盂的特定形状有关。结果表明盂唇下孔与年龄相关，因此在年轻患者中，若存在前上盂唇移位，在明确诊断之前应控制创伤的局部体征和肱二头肌附着点的受累情况。
