ABSTRACT

Main objective. Determine the ulnar surgery outcome in patients with MO. Material and methods. We reviewed performed in patients with MO between 1990 to 2002. We evaluated: gender, age at the time of surgery, range of motion, radial articular angle, ulnar translocation of the carpus. We divided patients in: Group 1, patients with exostosis resection; Group 2, with ulnar lengthening. Results. Nineteen patients, 4 bilateral, 11 (58%) boys and 8 (42%) girls. Thirteen forearms in Group 1, 10 forearms of Group 2. The age of surgery in Group 1 was of 10 years and 12 years in Group 2. The ulnar length discrepancy was: preoperatively –6 mm in Group 1 and –10 mm in the Group 2 and of –4 mm in Group 1 and 2 mm in Group 2 postoperatively. The Fogel’s radial articular angle was 40° in preoperative period and 31° in postoperative period this in the Group 2. Conclusions. We recommend: 1.- Osteochondroma excision at same time of ulnar lengthening; 2.- Ulnar lengthening until discrepancy is +2 mm because of forearm bones growing; 3.- Protect the forearm with a plaster cast to avoid a fracture, angulation or deformity, after removal of the external fixator for two weeks; 4.- Ulnar lengthening when: a) The Fogel´s angle is ›30°; b) Ulnar translocation of the carpus exists; c) Ulnar length discrepancy ± 10 mm; d) Radial head subluxations or dislocation exist, with pain and pronosupination disability.
