Acquired Madelung-like deformity in a gymnast.

High-level gymnastic training may cause clinical and radiographic changes in the wrist. A case is reported demonstrating bilateral closure of the ulnar side of the distal radius epiphyseal plate in a patient with a history of high-level gymnastic training. Cumulative microtrauma to the ulnar side of the distal radius epiphyseal plate may cause premature closure leading to a Madelung-like deformity.
