In summary, batter’s shoulder is a rare and only recently recognized entity. This condition is posterior shoulder instability caused by a missed attempt at hitting a pitch, especially with an outside pitch. The lack of counterforce from hitting a ball produces increased forces imparted on the posterior capsulolabral complex of the lead shoulder during batting. If the player fails conservative management, she or he can undergo an arthroscopic posterior labral repair instead of debridement. After treatment, the player can expect to return to play after approximately 6 to 7 months. Initial results from a small, retrospective series demonstrate greater than 90% excellent results. These findings are similar to current literature for arthroscopic treatment of posterior instability, which reports success rates that range from 75% to 91%. Longer-term follow-up will be needed to determine the natural history and prognosis or batter’s shoulder. Based on initial results, the authors predict good to excellent results for most players with batter’s shoulder who undergo proper treatment. Additionally, with the exception of switch hitters, the nonthrowing arm is affected. This can also improve the athlete’s return to play.
总之， batter’s shoulder 是一种罕见的、最近才被认识到的病症。这种情况是由于击球时未能击中球而导致的后肩不稳定，尤其是当球在外面时。击球时缺少反作用力会导致在击球时施加在主导肩部的后关节囊盂唇复合体上的力增加。如果球员不能接受保守治疗，她或他可以选择接受关节镜下后盂唇修复，而不是清创术。治疗后，大约 6 到 7 个月后，球员可以恢复比赛。来自一个小的、回顾性系列的初步结果表明，超过 90%的患者效果极好。这些发现与关节镜治疗后不稳定的现有文献相似，报告的成功率在 75%到 91%之间。需要进行更长期的随访来确定 batter’s shoulder 的自然史和预后。根据初步结果，作者预测大多数接受适当治疗的 batter’s shoulder 患者都将取得良好至极好的效果。此外，除了双打击球手外，非投球手臂也会受到影响。这也可以提高运动员的复出能力。
