Rates of shoulder and elbow pathology are well documented among competitive baseball players in the United States; however, little is known about the prevalence of these pathologies in the Dominican Republic (DR).
To report the epidemiology of shoulder and elbow pathology among participants at a Major League Baseball scouting event in Santo Domingo, DR.
Retrospective descriptive study.
All pitchers and position players who attended the 2021 scouting event were reviewed. Those with complete medical history, physical examination, imaging series, and radiology reports were included. All participants underwent shoulder and elbow radiography, while pitchers also underwent magnetic resonance imaging (MRI). All pathologic findings on imaging studies were recorded and compared among position players and pitchers.
Seventy-five participants (average age, 17.9 years) were reviewed (42 position players, 33 pitchers); 72% and 32% had ≥1 abnormal finding on elbow and shoulder radiographs, respectively. Position players had significantly higher numbers of elbow radiographic findings compared with pitchers (81% vs 57.6%, = 0.03) but similar numbers on shoulder radiograph (28.6% vs 33.3%, = 0.66). Position players had high numbers of acromioclavicular separation (14.3%) and little leaguer's shoulder (14.3%) on shoulder radiograph, with olecranon osteophytes (23.8%) and medial epicondyle nonunions (11.9%) prevalent on elbow radiograph. Pitchers had high numbers of rotator cuff pathology (93.9%), labral tears (75.8%), and Bennett lesions (51.5%). On elbow imaging, pitchers had high numbers of ulnar collateral ligament (UCL) abnormalities (81.8%), olecranon osteophytes (69.7%), osteochondral lesions (18.2%), and medial epicondyle nonunions (12.1%). Two pitchers had complete UCL disruption (6.1%), while 8 had partial tears (24.2%).
Dominican baseball prospects had high numbers of asymptomatic shoulder and elbow pathology on imaging studies. Knowledge of the prevalence of these pathologies can guide injury prevention programs in Dominican youth baseball.
在美国职业棒球运动员中，肩部和肘部病变的发生率已有充分记录；然而，对于这些病变在多米尼加共和国（DR）的患病率知之甚少。
报告在多米尼加共和国圣多明各举行的美国职业棒球大联盟球探活动参与者中肩部和肘部病变的流行病学情况。
回顾性描述性研究。
3级。
对参加2021年球探活动的所有投手和内场手进行了评估。纳入那些有完整病史、体格检查、影像系列和放射学报告的人。所有参与者均接受了肩部和肘部X线摄影，而投手还接受了磁共振成像（MRI）检查。记录影像研究中的所有病理发现，并在内场手和投手之间进行比较。
共评估了75名参与者（平均年龄17.9岁）（42名内场手，33名投手）；分别有72%和32%的参与者肘部和肩部X线片上有≥1项异常发现。与投手相比，内场手肘部X线片上的异常发现明显更多（81%对57.6%，P = 0.03），但肩部X线片上的异常发现数量相似（28.6%对33.3%，P = 0.66）。内场手肩部X线片上肩锁关节分离（14.3%）和小联盟肩（14.3%）的发生率较高，肘部X线片上鹰嘴骨赘（23.8%）和内上髁不愈合（11.9%）较为普遍。投手中肩袖病变（93.9%）、盂唇撕裂（75.8%）和贝内特损伤（51.5%）的发生率较高。在肘部影像检查中，投手尺侧副韧带（UCL）异常（81.8%）、鹰嘴骨赘（69.7%）、骨软骨损伤（18.2%）和内上髁不愈合（12.1%）的发生率较高。两名投手出现了完全性UCL断裂（6.1%），而8名投手出现了部分撕裂（24.2%）。
多米尼加棒球新秀在影像研究中无症状肩部和肘部病变的发生率较高。了解这些病变的患病率可为多米尼加青少年棒球运动的损伤预防计划提供指导。
