背景资料：青少年棒球运动员肱骨小头剥脱性骨软骨炎（OCD）的患病率和临床特征尚不清楚。目的：确定青少年竞技棒球运动员的OCD患病率，并调查这些患者的临床特征。研究设计：横断面和病例对照研究;证据等级：3。方法：共有2433名棒球运动员（平均年龄，14.5 +/- 1.5岁）属于初中和高中棒球俱乐部参加。运动员完成了一份问卷，每个运动员投掷手臂手肘通过超声检查进行了评估。超声检查结果异常的受试者通过放射学检查进一步检查。强迫症病变分为阶段的基础上，影像学结果，人口统计学数据进行了比较球员与非强迫症lesions.Results：骨软骨炎剥脱性肱骨小头82（3.4%）肘超声发现。与没有损伤的球员相比，有强迫症损伤的球员开始打棒球的年龄更早（P = 0.016），有更长的比赛时间（P = 0.0013），并且经历了更多的现在（P = 0.0025）和过去（P <0.0001）肘部疼痛。两组之间的位置没有差异（P = 0.26）。68名患者接受了进一步的强迫症放射学检查（放射学检查、计算机断层扫描、磁共振成像）。在这些球员中，有10名（14.7%）被归类为患有I期强迫症（放射性同位素阶段）; 26（38.2%），II期（碎裂阶段）; 9（13.2%），第三阶段（游离体阶段）; 9（13.2%），IV期（剩余阶段）;和14结论：青少年棒球运动员肱骨小头强迫症的患病率为3.4%，包括潜伏病例。有强迫症病变的球员开始打棒球的年龄较早，打了更长的时间，并经历了更多的肘部疼痛。球员目前的棒球位置可能与青少年存在强迫症病变无关。
Background: The prevalence and clinical characteristics of osteochondritis dissecans (OCD) of the humeral capitellum among adolescent baseball players are unknown.Purpose: To determine the OCD prevalence in adolescent competitive baseball players and to investigate the clinical characteristics of these patients.Study Design: Cross-sectional and case-control study; Level of evidence, 3.Methods: A total of 2433 baseball players (mean age, 14.5 +/- 1.5 years) belonging to junior high school and high school baseball clubs were enrolled. Players completed a questionnaire, and the elbow of each player's throwing arm was assessed by ultrasonography. Participants with abnormal results on ultrasonography were further examined through radiographic study. The OCD lesions were classified into stages based on radiographic results, and demographic data were compared between players with and without OCD lesions.Results: Osteochondritis dissecans of the humeral capitellum was found in 82 (3.4%) elbows by ultrasonography. Players with an OCD lesion began playing baseball at an earlier age (P = .016), had a longer duration of competitive play (P = .0013), and had experienced more present (P = .0025) and past (P < .0001) elbow pain compared with players without a lesion. There were no differences between the 2 groups in the position played (P = .26). Sixty-eight patients underwent further radiographic examination for OCD (radiography, computed tomography, magnetic resonance imaging). Of these players, 10 (14.7%) were classified as having stage I OCD (radiolucent stage); 26 (38.2%), stage II (fragmentation stage); 9 (13.2%), stage III (loose body stage); 9 (13.2%), stage IV (residual stage); and 14 (23.5%), stage V (postoperative stage).Conclusion: The prevalence of OCD of the humeral capitellum, including latent cases, was 3.4% among adolescent baseball players. Players with OCD lesions began playing baseball at earlier ages, had played for longer periods, and had experienced more elbow pain. The player's current baseball position may not be related to the existence of OCD lesions in adolescents.
