Overuse injuries of the shoulder and elbow are common in the skeletally immature throwing
athlete. This review goes beyond describing the classic imaging findings of Little
League shoulder and elbow and probes deeper into new insights suggesting a unifying
etiology of metaphyseal or metaphyseal equivalent injury as the cause of many of the
bony lesions described. Injury patterns change depending on the athlete's skeletal
maturation, and the spectrum of abnormalities is reviewed.
