Although middle glenohumeral ligament (MGHL) variations have been shown in the literature, their clinical effect and relationship with intra-articular pathologies have yet to be revealed, except for the Buford complex. This study was designed to classify MGHL and to reveal its relationship with clinical pathologies.
A total of 843 consecutive shoulder arthroscopies were evaluated retrospectively, and a classification system was proposed for MGHL with regard to its structure and its relation to the anterior labrum. The associations of each MGHL type with superior labrum anterior-posterior (SLAP) lesions, subscapularis tears, and anterior instability were investigated.
MGHL variations were grouped into 6 types according to the classification. A significant difference in favor of type 6 MGHL (Buford complex) was observed in the distribution of SLAP lesions (P < .001). There was no significant difference between MGHL types and the distribution of anterior instability history (P = .131) and subscapularis tears (P = .324).
SLAP lesions accompany type 6 MGHLs (Buford complex) significantly more frequently than other types. There is also a negative relation between the anterior instability and thicker MGHL variants.
虽然文献中已经报道了肩盂中韧带（MGHL）的变异，但除了 Buford 复合体之外，其临床意义及其与关节内病变的关系尚未被揭示。本研究旨在对 MGHL 进行分类，并揭示其与临床病理的关系。
回顾性分析了 843 例连续肩关节镜检查，提出了一种根据 MGHL 结构及其与前盂唇关系的分类系统。研究了每种 MGHL 类型与上盂唇前-后（SLAP）损伤、肩胛下肌撕裂和前向不稳定的关系。
根据分类，MGHL 变异分为 6 型。在 SLAP 损伤的分布中，6 型 MGHL（Buford 复合体）明显更为常见（P <.001）。MGHL 类型与前向不稳定病史（P =.131）和肩胛下肌撕裂（P =.324）的分布之间无显著差异。
与其他类型相比，SLAP 损伤更常伴有 6 型 MGHL（Buford 复合体）。前向不稳定与较厚的 MGHL 变异也存在负相关。
