Abstract
As an increasing number of young people participate in sports such as baseball, cases of little league shoulder (LLS) are encountered more often. LLS is usually treated conservatively, and education and rehabilitation are important for helping young athletes prevent LLS. Metaphyseal sclerosis on imaging is useful for diagnosing patients’ condition. If metaphyseal sclerosis is present, LLS should be suspected; otherwise, a traumatic epiphyseal fracture should be considered. Banning throwing activity is crucial. We report treatment of LLS with metaphyseal sclerosis including rest, which facilitated a gradual return to sports.
