This study investigated the usefulness of ultrasonography in medical examinations for detecting elbow injuries, especially capitellar osteochondritis dissecans, among young baseball players.
Players with current or previous elbow joint pain were enrolled. Medical examinations (range of motion, tenderness, and stress tests) were performed with (2012-2016) or without (2007-2011) ultrasonography. Players with abnormal examination results were advised to undergo additional examinations at a local orthopedic clinic. Differences in the rates of capitellar osteochondritis dissecans detection, secondary examination, and elbow injury prevalence were compared between players who did and did not undergo ultrasonography.
We identified 1045 baseball players, aged 9-12 years, who required medical examinations for elbow injuries. Medical examinations without ultrasonography were performed in 346 players (group A), and examinations with ultrasonography were performed in 556 players (group B). Capitellar osteochondritis dissecans was present in 0.3% (1/346) of group A players and 3.0% (17/556) of group B players (p = 0.003). The secondary examination consultation rates were 51.2% (62/121) and 66.0% (270/409) in groups A and B, respectively (p = 0.004).
Ultrasonography performed as a part of a medical examination can help detect elbow injuries, especially capitellar osteochondritis dissecans, in baseball players. Using ultrasonography in conjunction with medical examinations may contribute to a better understanding of elbow injuries in baseball players and improve consultation rates. Thus, ultrasonography is essential for the evaluation of elbow injuries in young baseball players.
本研究调查了超声检查在年轻棒球运动员肘部损伤（尤其是肱骨小头剥脱性骨软骨炎）医学检查中的实用性。
纳入有当前或既往肘关节疼痛的运动员。在2012 - 2016年期间对运动员进行医学检查（包括活动范围、压痛和应力试验）时使用超声检查，在2007 - 2011年期间则不使用超声检查。检查结果异常的运动员被建议到当地骨科诊所接受进一步检查。比较接受和未接受超声检查的运动员在肱骨小头剥脱性骨软骨炎检出率、二次检查率和肘部损伤患病率方面的差异。
我们确定了1045名年龄在9至12岁之间、需要进行肘部损伤医学检查的棒球运动员。346名运动员（A组）未使用超声进行医学检查，556名运动员（B组）使用超声进行了检查。A组运动员中肱骨小头剥脱性骨软骨炎的患病率为0.3%（1/346），B组为3.0%（17/556）（p = 0.003）。A组和B组的二次检查咨询率分别为51.2%（62/121）和66.0%（270/409）（p = 0.004）。
作为医学检查一部分的超声检查有助于检测棒球运动员的肘部损伤，尤其是肱骨小头剥脱性骨软骨炎。将超声检查与医学检查结合使用可能有助于更好地了解棒球运动员的肘部损伤并提高咨询率。因此，超声检查对于评估年轻棒球运动员的肘部损伤至关重要。
