Radiopalmar opening wedge osteotomy was used in 11 female patients (T2 wrists) with Madelung's deformity who ranged in age from 9 to 31 years. Five patients met the radiographic criteria for generalized dyschondrosteosis. Clinically, there was dissatisfaction with the appearance of the wrist. The principal motion deficits were in radiocarpal extension and forearm pronosupination associated with varying degrees of discomfort with sustained activity. All had a decreased radioulnar angle, lunate subluxation shown radiographically, and various degrees of dorsal subluxation of the ulnar head. Indications for surgery were pain, limited motion, cosmetic appearance, and progressive deformity in two immature patients. Biplanar corrective opening wedge osteotomy of the radius was performed with iliac crest graft. Three patients had an added ulnar recession. Fixation was with a plate or Kirschner wire. Supplementary distracting external fixation was used in six cases. The follow-up period averaged 48 months. Pain relief in all patients was satisfactory. Range of motion and grip strength were not influenced. The radioulnar angle improved by 11°, but lunate subluxation was minimally changed. Length of the forearm and bowed appearance of the forearm were improved. Reduction of the radioulnar joints was improved but remained incongruous.
