Little League shoulder was first described by Dotter  in 1953. This injury is commonly known as proximal humeral epiphysiolysis, a confusing term, because Little League shoulder is likely an overuse or stress injury of the proximal humeral growth plate or the adjacent metaphysis rather than an epiphyseal injury. Little League shoulder is most commonly seen in 13- to 16-year-old boys. The etiology is likely repetitive rotational stress . The physis is particularly prone to injury in this age group because of accelerated growth and the majority of longitudinal humeral growth occurring at the proximal humeral physis. The classic radiographic signs are physeal widening, lateral fragmentation or calcification, sclerosis, demineralization and cystic change . Treatment consists of rest and physical therapy.
