Chronic slipping of bilateral distal humeral epiphyses in a gymnastist

We report a case of an 11-year-old male patient who sustained separation of the distal humeral epiphyses bilaterally after 2 years of gymnastics, without a clear mechanism of injury. This patient had been using the vault since he was 9 years old, although children of that age do not normally perform on the vault. When gymnasts place their hands on the vault with their elbows flexed and subsequently extend their elbows to push off, the biomechanical load is placed equally on the right and left arms. Consequently, this type of repeated stress induces injury to the epiphyseal cartilages bilaterally, resulting in chronic progression of separation of the distal humeral epiphyses.
