To explore the patterns and trends of upper limb injuries in Major League Baseball (MLB).
Descriptive Epidemiological Study.
The MLB website was screened for injuries between 2010 and 2016, inclusive.
Players that were placed on the Injured Lists (IL) due to upper limb injuries.
The players' position, injury location, injury information, date of injury, and time spent on the IL were collected.
A total of 3512 injuries were documented; 1609 injuries (49%) affected the upper limb (n = 1609). On average, players were placed on the IL for 71 days (std dev = 57 days) due to these injuries. The shoulder was the anatomic location most prone to injury (35%). The elbow had the highest average days on IL (94 days; std dev = 63 days), significantly higher than all other anatomic locations (P < 0.001). Strain was the most cited cause for upper limb injuries. Pitchers had a significantly higher mean incidence rate (MIR) than fielders and catchers for shoulder, elbow, arm, and forearm injuries. Pitchers had significantly lower wrist and hand injury MIRs when compared to fielders and catchers. April had the highest burden of injuries with 380 injuries (24%) recorded. Surgery was performed on 225 injuries (14%).
Upper limb injuries are prevalent in the MLB, especially among pitchers. The shoulder is the anatomic location most prone to injury. Better understanding of the trends and patterns of these injuries will help in establishing better prevention policies.
探究美国职棒大联盟（MLB）上肢损伤的模式和趋势。
描述性流行病学研究。
筛选 2010 年至 2016 年期间 MLB 网站上的上肢损伤。
因上肢损伤而被列入伤病名单（IL）的球员。
收集球员的位置、受伤部位、受伤信息、受伤日期和伤病停赛时间。
共记录了 3512 次损伤，其中 1609 次（49%）影响上肢（n=1609）。这些损伤平均导致球员伤病停赛 71 天（标准差 57 天）。肩部是最容易受伤的解剖部位（35%）。肘部的伤病停赛时间最长（94 天；标准差 63 天），明显高于其他所有解剖部位（P<0.001）。拉伤是上肢损伤最常见的原因。与外野手和捕手相比，投手的肩部、肘部、手臂和前臂损伤的平均发病率（MIR）明显更高。与外野手和捕手相比，投手的腕部和手部损伤 MIR 明显较低。4 月的上肢损伤负担最高，记录了 380 次损伤（24%）。有 225 次损伤（14%）接受了手术治疗。
上肢损伤在美国职棒大联盟中很常见，尤其是投手。肩部是最容易受伤的解剖部位。更好地了解这些损伤的趋势和模式将有助于制定更好的预防政策。
