Abstract：
BACKGROUND: Large, circumferential glenoid labral tears are an uncommon injury affecting young, athletic patients. There are limited data describing the clinical presentation of patients with larger tears, especially 270° and 360° labral tears. Additionally, examination and imaging findings have poor reliability in diagnosing these tears. The purpose of this study was to determine the clinical presentation among patients presenting with small (less than 180°), medium (180°-270°), and large (270°-360°) labral tears.
METHODS: This is a retrospective comparative study of consecutive patients surgically managed by a single shoulder surgeon for all glenoid labral tears from 2018-2022. The primary outcome was demographic and preoperative clinical risk factors. Demographic data including age, sex, hand dominance, body mass index, as well as clinical presentation (subluxation vs. dislocation, instability history, and participation in contact sports) were recorded.
RESULTS: A total of 188 patients met the inclusion criteria: 101 of 188 (53.70%) patients with small tears, 43 of 188 (22.90%) patients with medium tears, and 44 of 188 (23.40%) patients with large tears. Individuals with large and medium-sized labral tears were more likely to have participated in contact sports compared to those with smaller labral tears (P = .003). Medium and smaller tears were more likely to present as dominant-side injury (P = .02). Furthermore, medium and large tears were more likely to present with anterior instability symptoms compared with smaller tears, which more frequently presented with posterior instability and pain (P = .003).
CONCLUSIONS: Males participating in contact sports were the most common demographic population presenting with large, 270°-360° labral tears. Instability was the primary complaint rather than pain, and compared with small tears, medium and large tears were more likely to present with primary anterior instability. Although arthroscopic repair of 270°-360° labral tears can yield excellent clinical outcomes similar to smaller tears, identifying factors associated with larger glenoid labral tears may help in surgical planning and patient counseling.

摘要：
背景：大，环状关节盂唇撕裂是一种罕见的损伤，影响年轻人，运动患者。描述泪液较大患者临床表现的数据有限，尤其是270度和360度的唇撕裂。此外,检查和影像学检查结果对这些泪液的诊断可靠性较差.这项研究的目的是确定患者的临床表现与小（小于180度），中等（180-270度），和大（270-360度）唇撕裂。
方法：这是一项回顾性比较研究，研究了2018-2022年由单肩外科医生手术治疗的所有关节盂唇撕裂的连续患者。主要结果是人口统计学和术前临床危险因素。人口统计数据，包括年龄，性别,手支配,BMI,以及临床表现(半脱位与脱位，不稳定的历史，和参与接触运动)被记录。
结果：共188例符合纳入标准：101/188例（53.70%）小泪液患者，43/188（22.90%）患者中泪液，44/188(23.40%)患者伴有大泪液。与具有较小的唇眼泪的人相比，具有大中型唇眼泪的人更有可能参加接触运动（p=0.003）。中等和较小的眼泪更可能表现为显性侧损伤（p=0.02）。此外，与较小的眼泪相比，中等和大的眼泪更可能出现前不稳定症状，更常见的是后部不稳定和疼痛(p=0.003)。
结论：参加接触运动的男性是最常见的人口统计人群，270度到360度的唇缘眼泪。不稳定是主要的主诉而不是疼痛，和小小的眼泪相比，中型和大型泪液更可能出现原发性前不稳。虽然关节镜下修复270至360度的唇唇撕裂可以产生与较小的撕裂相似的优异的临床结果，确定与较大关节盂唇撕裂相关的因素可能有助于手术计划和患者咨询.
