Lower extremity muscle tears are common sports injuries. The British Athletics Muscle Injury Classification (BAMIC) may provide clinical guidance for tears although its value in American football and college athletes is unknown.
Clinical outcomes, specifically time to return to play (RTP) (TRTP), in college American football athletes with activity-related hamstring (HS) and quadriceps (QD) tears will be associated with BAMIC.
Retrospective cohort study.
Level 3.
American football college athletes who sustained a HS or QD tear and underwent magnetic resonance imaging within 7 days at 1 institution during the 2023 season were included. TRTP and reinjury rate (RIR) for HS and QD tears classified by BAMIC and injury characteristics were evaluated.
Of the 24 HS and 10 QD tears in 21 (17.3%) of 121 athletes (20 ± 1.2 years; 100.0% male), most (60.0%) were BAMIC 2a-3b. Most (89.3%) injuries occurred before the season, and all occurred in practice. Overall median TRTP was 26 days (interquartile range, 17.8-33.0), translating to about 4 weeks missed play. The RIR was 19.0% (4/21). Most (75.0%) reinjuries occurred before RTP. There was no significant relationship between BAMIC and TRTP, although TRTP was less for grade 0 injuries and greater TRTP for injury site "c," albeit with small effect sizes.
Activity-related HS and QD tears are common in American football college athletes, particularly in preseason and practice. Injured athletes missed about 3 to 4 games, regardless of BAMIC, with 1 in 5 athletes suffering a reinjury. There was no relationship between BAMIC or muscle group and TRTP.
This appraisal of BAMIC in college and American football athletes highlights the prevalence of muscle tears and the need for prevention. Although BAMIC lacked value in this study, larger studies are needed to evaluate BAMIC in this population.
下肢肌肉撕裂是常见的运动损伤。英国田径肌肉损伤分类法（BAMIC）可能为肌肉撕裂提供临床指导，但其在美国橄榄球和大学运动员中的价值尚不清楚。
在与活动相关的腘绳肌（HS）和股四头肌（QD）撕裂的大学美式橄榄球运动员中，临床结果，特别是恢复比赛时间（RTP）（TRTP），将与BAMIC相关。
回顾性队列研究。
3级。
纳入2023赛季在1家机构内7天内发生HS或QD撕裂并接受磁共振成像检查的大学美式橄榄球运动员。评估按BAMIC分类的HS和QD撕裂的TRTP和再损伤率（RIR）以及损伤特征。
121名运动员（20±1.2岁；100.0%为男性）中有21名（17.3%）发生了24例HS撕裂和10例QD撕裂，大多数（60.0%）为BAMIC 2a - 3b级。大多数（89.3%）损伤发生在赛季前，且均发生在训练中。总体中位TRTP为26天（四分位间距，17.8 - 33.0），相当于约4周的缺赛时间。RIR为19.0%（4/21）。大多数（75.0%）再损伤发生在RTP之前。BAMIC与TRTP之间无显著关系，尽管0级损伤的TRTP较短，损伤部位“c”的TRTP较长，尽管效应量较小。
与活动相关的HS和QD撕裂在大学美式橄榄球运动员中很常见，尤其是在季前赛和训练中。受伤运动员无论BAMIC分级如何，都缺赛约3至4场，五分之一的运动员会再次受伤。BAMIC或肌肉群与TRTP之间无关系。
对大学和美式橄榄球运动员中BAMIC的评估突出了肌肉撕裂的普遍性以及预防的必要性。尽管BAMIC在本研究中缺乏价值，但需要更大规模的研究来评估该人群中的BAMIC。
