The purpose of this study was to evaluate the correlation between the morphological classification of the middle glenohumeral ligament (MGHL) and subscapularis tears and to evaluate whether surgical release of the MGHL is warranted in patients with subscapularis tears. A retrospective analysis was performed on the surgical videos of shoulder arthroscopic rotator cuff repair surgeries conducted by the same surgeon from September 2020 to September 2021. The MGHL was classified morphologically into two types: overall classification and lateral insertion classification, and the occurrence of subscapularis tears was recorded for each type. The chi-square test was used to analyze the differences in the number of subscapularis tears among the classification groups. Out of 122 patients, 44 (36.07%) were male and 78 (63.93%) were female, with an average age of 55.03 ± 7.35 years. According to the overall classification of MGHL, there were 54 cases of Type I (44.26%), 32 cases of Type II (26.23%), 28 cases of Type III (22.95%), 2 cases of Type IV (1.64%), and 6 cases of Type V (4.92%). For the lateral insertion classification of MGHL, there were 53 cases of Type A (43.44%) and 69 cases of Type B (69%). There was no statistically significant difference in the number of subscapularis tears among the classification groups . This retrospective study found no correlation between the morphological classification of MGHL and subscapularis tears. For patients with rotator cuff tears who do not have frozen shoulder, caution should be exercised when performing release of the MGHL.
本研究的目的是评估肩肱中韧带（MGHL）的形态学分类与肩胛下肌撕裂之间的相关性，并评估肩胛下肌撕裂患者是否有必要进行MGHL手术松解。对同一位外科医生在2020年9月至2021年9月期间进行的肩关节镜下肩袖修复手术的手术视频进行回顾性分析。MGHL在形态学上分为两种类型：整体分类和外侧附着分类，并记录每种类型中肩胛下肌撕裂的发生情况。采用卡方检验分析分类组间肩胛下肌撕裂数量的差异。122例患者中，男性44例（36.07%），女性78例（63.93%），平均年龄55.03±7.35岁。根据MGHL的整体分类，I型54例（44.26%），II型32例（26.23%），III型28例（22.95%），IV型2例（1.64%），V型6例（4.92%）。对于MGHL的外侧附着分类，A型53例（43.44%），B型69例（69%）。各分类组间肩胛下肌撕裂数量无统计学差异。这项回顾性研究发现MGHL的形态学分类与肩胛下肌撕裂之间没有相关性。对于没有肩周炎的肩袖撕裂患者，在进行MGHL松解时应谨慎。
