Little leaguer’s shoulder is a syndrome involving the proximal humeral epiphyseal plate and has been reported in adolescent athletes between 13-16 years of age. We present an adolescent case with radiological findings of little leaguer’s shoulder syndrome in a non-athletic patient. The patient had applied significant rotational stress to the proximal humeral physis as a result of overuse due to physiotherapy, but the left asymptomatic side appeared more affected radiologically, which led to the idea that this may be a physiological change that occurs in adolescents. We thus evaluated the anteroposterior radiography of 10 healthy male adolescents of the same age with no skeletal or muscular complaints. We demonstrated a minimal widening of the lateral part of the proximal humeral epiphysis in two of these 10 patients. We believe little leaguer’s shoulder should also be considered in adolescents with proximal humeral pain and a history of overuse. A larger study must be conducted to investigate whether these finding may be a variation of physiological development. Keywords : little leaguer’s shoulder, proximal humeral physeal widening, adolescents, physiological development.
