Stress fracture of the ulnar diaphysis: review of the literature and report of a case.

A 22-year-old athlete developed chronic pain in the forearm aggravated by weight lifting. Physical examination revealed localized tenderness at the junction of the middle and distal third of the ulnar diaphysis. X-ray films revealed an osteolytic lesion at the same level. The patient developed an overt fracture at the same site when he failed to stop sports activities against advice. The fracture healed uneventfully with immobilization in a sleeve cast.
