Very little data exist on latissimus dorsi (LD) and teres major (TM) injuries in professional baseball pitchers.
This review was undertaken to report on the management and outcomes of baseball pitchers with injury to 1 or both of these muscles.
Case series; Level of evidence, 4.
A retrospective review of 16 professional baseball pitchers diagnosed and treated for an LD and/or TM tear between 2002 and 2008 was performed. Magnetic resonance imaging confirmed the diagnosis in all cases. The mean age was 28.1 years. All were treated nonoperatively with rest, rehabilitation, and return to pitching after a throwing program. The injuries included tendon avulsions in 6 athletes and strains in 10. Length of disabled time, return to prior level of pitching, and recurrences were noted.
Fifteen of 16 pitchers (94%) returned to the same or higher level of play. The mean time to throwing was 35.6 days. Mean time to pitching was 61.9 days. Nine of 16 injuries (56%) were season-ending. Mean total time lost for athletes returning the same season was 82.4 days. Two of 16 pitchers (13%) sustained recurrent injuries. Prior shoulder and elbow injuries were noted in 75% (12 of 16).
Injury of the LD and/or TM can occur in pitchers. Nonoperative treatment is successful in allowing a return to high-level pitching.
在职业棒球投手中，关于背阔肌（LD）和大圆肌（TM）损伤的数据很少。
本综述旨在报告 1 或 2 种肌肉损伤的棒球投手的治疗和结果。
病例系列；证据水平，4。
回顾性分析了 2002 年至 2008 年间诊断和治疗 LD 和/或 TM 撕裂的 16 名职业棒球投手。所有病例均经磁共振成像（MRI）确诊。平均年龄为 28.1 岁。所有患者均接受非手术治疗，包括休息、康复和在投掷方案后恢复投球。损伤包括 6 名运动员的肌腱撕脱和 10 名运动员的拉伤。记录了残疾时间、恢复到先前投球水平和复发情况。
16 名投手中有 15 名（94%）恢复到相同或更高的比赛水平。投掷的平均时间为 35.6 天。平均投球时间为 61.9 天。16 次损伤中有 9 次（56%）为赛季结束伤。同一赛季返回的运动员总损失时间平均为 82.4 天。16 名投手中有 2 名（13%）发生复发性损伤。75%（12 名/16 名）的运动员有先前的肩部和肘部损伤。
投手可能会发生 LD 和/或 TM 损伤。非手术治疗可成功恢复高水平投球。
