Discussion

The slipped humeral epiphysis is a chronic stress injury in the dominant arm of adolescents who participate in ovehead sports such as baseball. It is most commonly seen in 12-15 y/o boys, frequently pitchers. Limitations on the number of pitches that a little league pitcher can throw have been recommended by the official Little League organization.
