A review of the orthopaedic literature suggests that traumatic ulnar physeal arrest associated with radial fracture is a rare occurrence. Twenty-three cases of traumatic ulnar physeal arrest have been reported in patients with distal radius fractures, and we report five additional cases. A classification system for the distal ulnar growth deformities is proposed, and the compensatory radial changes are reviewed. Surgical indications for treatment include cosmetic deformity, progressive carpal subluxation, and decreased range of motion. Surgical options for treatment are discussed and include epiphysiodesis, ulnar lengthening, radial osteotomy, and the Suave-Kapandji procedure.
