Abstract

Purpose of the study: The critical shoulder angle (CSA) is formed by the combination of glenoid inclination and acromial index and has been shown related to rotator cuff tears and glenohumeral osteoarthritis. SLAP lesions today have an important place among bicipitolabral pathologies that cause intensive shoulder pain. We aimed to investigate the relationship between CSA and glenoid depth and SLAP lesions.

Material and methods: Between March 2017 and January 2022, 279 consecutive shoulder arthroscopy patients' MRI images were retrospectively examined. After the exclusion criteria, 191 patients were eligible. Patients with SLAP lesions (n=37) were assembled as the study group (Group 1), and patients with intact superior labrum (n=154) were named as the control group (Group 2). Critical shoulder angle (CSA) and glenoid depth measurements were performed using the preoperative MRI images.

Results: A total of 191 patients, of whom 84 were male (44%) were included. The mean age was 49.9±14.96 (range 18-79). There was a statistically signifi cant difference between the SLAP group (Group 1) and the control group (Group 2) in terms of CSA (p=0.032). The mean CSA was 31.66°±3.51° in Group 1 and 33.57° ±5.01° in Group 2. The cut-off value for CSA in patients with SLAP lesions was calculated as 32.85° and the area under the curve was 0.61, therefore a satisfactory association was observed between the groups. The mean glenoid depth was 4.32 ±1.25 mm in Group 1, and 4.39 ±0.32 mm in Group 2. There was no statistically signifi cant difference between the groups in terms of glenoid depth (p=0.136) and also no association between the glenoid depth and SLAP lesions was observed (cut-off=4.45 mm, AUC=0.32).

Conclusions: Low CSA is associated with SLAP lesions, just as in glenohumeral osteoarthritis. Further prospective clinical studies are needed to enlighten the predisposing effect of CSA to SLAP lesions and the success of superior labral repairs.

Level of evidence: Retrospective comparative study, Level III.

SLAP病变与临界肩角和盂唇深度之间的关系

研究目的临界肩角（CSA）由盂倾角和肩峰指数组合而成，已被证明与肩袖撕裂和盂肱骨关节炎有关。如今，SLAP 病变在导致肩部剧烈疼痛的双肱骨病变中占有重要地位。我们旨在研究CSA和盂深与SLAP病变之间的关系：2017年3月至2022年1月，我们对279例连续肩关节镜检查患者的MRI图像进行了回顾性研究。排除标准后，191 名患者符合条件。SLAP病变患者（n=37）作为研究组（第1组），上唇盂完整的患者（n=154）作为对照组（第2组）。利用术前核磁共振图像测量肩关节临界角（CSA）和盂深度：结果：共纳入 191 例患者，其中男性 84 例（44%）。平均年龄为 49.9±14.96（18-79 岁）。就 CSA 而言，SLAP 组（第 1 组）与对照组（第 2 组）之间存在显著统计学差异（P=0.032）。第 1 组的平均 CSA 为 31.66°±3.51°，第 2 组为 33.57°±5.01°。SLAP 病变患者 CSA 的临界值为 32.85°，曲线下面积为 0.61，因此观察到两组之间存在令人满意的关联。第 1 组的平均盂深为 4.32 ±1.25 mm，第 2 组为 4.39 ±0.32 mm，两组间的盂深差异无统计学意义（P=0.136），也未观察到盂深与 SLAP 病变之间的关联（临界值=4.45 mm，AUC=0.32）：结论：与盂肱骨关节炎一样，低CSA也与SLAP病变有关。需要进一步开展前瞻性临床研究，以了解CSA对SLAP病变的易感性以及上唇修补术的成功率：回顾性比较研究，III级。
