Objective To explore a method of treating Madelung deformity. Methods Seven cases of Madelung deformity had been treated with the excision of ulnar carpi ulnaris segment and distal osteotomyof radius and tight constrict of extensor carpi ulnaris from Mar. 2000 to Nov. 2003. The angle of ulnar tilting was 37-70° and the angle of volar tilting wasover 16°. A longitudinal incision on each side of the radius and ulnar was made, the ulna was excised about 2-3 cm segment. Then the fracture of ulna was fixed by double across vertical steel wire and the radius was fixed with medullarywire. Lastly the extensor carpi ulnaris was shortened and sutured after the wrist was located restposition. Results After surgery, the deformity of wrist was improved and pain-free in the seven cases. The angle of ulnar tilting was reduced to 22-24°. The angle of volar tilting was reduced to 15° below. Follow-ups were conducted inthe 7 patients for 2 years in average. The activity of wrist joint and the rotation of forearm recovered from those before operation. The wrist joint could stretch fully. Conclusion This method of treating Madelung proves to be effective inrecovering deformity, releasing pain, improving function, and reducing traumatic osteoarthritics of the distal radioulnar joint.
