Shoulder instability attributed to glenoid labral tears is common among National Collegiate Athletic Association (NCAA) football players. Certain repetitive activities by player position may contribute to instability.
To compare the location of labral tears among player positions in NCAA Division I football.
Cross-sectional study.
We conducted a review of football players who underwent shoulder labral repair between 2000 and 2020 at a single institution. Inclusion criteria were NCAA Division I level, diagnosis of shoulder instability, and labral tear requiring arthroscopic repair. Exclusion criteria were prior surgery on injured shoulder and incomplete medical records. Players were divided into 3 groups: line players (offensive and defensive linemen, defensive end), skill players (defensive back, wide receiver, running back, and quarterback), and hybrid players (linebacker and tight end). Labral tear location and size were recorded using the clockface method and categorized into 6 zones: superior, anterosuperior, anteroinferior, inferior, posteroinferior, and posterosuperior. Comparison of variables was performed using chi-square test or Fisher exact test (categorical) and 1-way analysis of variance or Kruskal-Wallis test (continuous). The Spearman rank-order correlation was used to assess relationships between continuous data.
Of the 53 included players, 37 (70%) were offensive linemen, defensive linemen, and linebackers. There were 29 line players, 11 skill players, and 13 hybrid players. Line players represented 55% of included players and had the most total labral tears as compared with all groups. Hybrid players had a significantly higher percentage of posterosuperior tears than line players (92% vs 52%; = .015) and skill players (92% vs 27%; = .002). Skill players had a significantly higher percentage of anterior tears at 3:00-4:00 and 5:00-6:00 when compared with hybrid players (82% vs 15%, = .003; 82% vs 31%, = .012, respectively). There was a positive correlation between labral tear size and number of suture anchors (; = .010).
In this study of NCAA Division I football players, skill players had a higher proportion of anteroinferior labral tears, and hybrid players had a higher proportion of posterosuperior labral tears.
在全国大学体育协会（NCAA）的橄榄球运动员中，因盂唇撕裂导致的肩部不稳定很常见。运动员因位置不同而进行的某些重复性活动可能会导致肩部不稳定。
比较NCAA一级橄榄球联赛中不同位置球员的盂唇撕裂位置。
横断面研究。
我们回顾了2000年至2020年期间在单一机构接受肩部盂唇修复的橄榄球运动员。纳入标准为NCAA一级水平、肩部不稳定诊断以及需要关节镜修复的盂唇撕裂。排除标准为受伤肩部既往手术史和不完整的病历。球员分为3组：线卫（进攻线卫、防守线卫、防守端锋）、技术球员（防守后卫、外接手、跑卫和四分卫）和混合型球员（线卫和近端锋）。使用钟面法记录盂唇撕裂的位置和大小，并分为6个区域：上、前上、前下、下、后下和后上。使用卡方检验或费舍尔精确检验（分类变量）以及单因素方差分析或克鲁斯卡尔 - 沃利斯检验（连续变量）进行变量比较。使用斯皮尔曼等级相关来评估连续数据之间的关系。
在纳入的53名球员中，37名（70%）是进攻线卫、防守线卫和线卫。有29名线卫、11名技术球员和13名混合型球员。线卫占纳入球员的55%，与所有组相比，其总的盂唇撕裂数量最多。混合型球员后上撕裂的比例显著高于线卫（92%对52%；P = 0.015）和技术球员（92%对27%；P = 0.002）。与混合型球员相比，技术球员在3:00 - 4:00和5:00 - 6:00处前侧撕裂的比例显著更高（分别为82%对15%，P = 0.003；82%对31%，P = 0.012）。盂唇撕裂大小与缝合锚数量之间存在正相关（P = 0.010）。
在这项针对NCAA一级橄榄球运动员的研究中，技术球员前下盂唇撕裂的比例较高，而混合型球员后上盂唇撕裂的比例较高。
