A X-Ray Evaluation Of 21 Young Baseball Pitchers.}, year = {2008}, doi = {10.1136/bjsm.2007.044503}, publisher = {British Association of Sport and Excercise Medicine}, abstract = {Objective: To evaluate the prevalence of X-rays changes in the proximal humerus growth plate of 21 young pitchers. \<br\> Design: Case Series\<br\> Setting: This study was conducted at the Department of Orthopedics and Traumatology, ABC Faculty of Medicine, Santo Andre, SP {\textendash}Brazil. Terciary institution.\<br\> Patients: We studied 21 male adolescent baseball pitchers with mean age 14.5 years selected from the Brazilian National Team.\<br\> Interventions: The patients were submited to X rays evaluations of the shoulders\<br\> Main Outcome Measuraments: The patients shoulders X rays were studied to look for changes in the proximal humeral groth plate and correlated to clinical findings. \<br\> Results: Fourteen athletes (66\%) had radiographic changes in the proximal humerus growth plate. Nine of these 14 cases (64\%) where the observers found radiographic changes did not complain of pain. We also observed that in only 11 cases there was a correlation between the clinical and radiographic evaluations.\<br\> Conclusion: We concluded that radiographic change in the proximal humerus growth plate was found in 66\% of the cases and that no significant correlation was found with the clinical evaluation. A presence of widening of the growth plate of the proximal humerus of young pitchers{\textquoteright} dominant shoulder can occur even in asymptomatic athletes. Probably this widening represents the evolution, in the future, to a greater retroversion of their dominant shoulders.}, issn = {0306-3674}, URL = {https://bjsm.bmj.com/content/early/2008/02/28/bjsm.2007.044503}, eprint = {https://bjsm.bmj.com/content/early/2008/02/28/bjsm.2007.044503.full.pdf}, journal = {British Journal of Sports Medicine} }
