Six patients with complications caused by malunion of the distal radius such as pain, ROM disturbance, entrapment neuropathy, etc were operated on by corrective osteotomy. Patients comprised five males and one female, ranging in age from 17 to 64 years (average age: 45.8 years). Their deformities were graded according to Frynkman's classification. Corrective osteotomy of the radius with bone grafting was performed in five and in one patient ulnar shortening was carried out. Excellent results were obtained in 5 cases and good in one. Four patients with neurological symptoms of the hand were cured by the operation. Average improvement of palmar tilt, radial inclination and ulnar variation were 23.6°, 6.2° and 1.8mm respectively. In conclusion, corrective osteotomy for malunion of the distal radius is thought to be very effective.
