The treatment of lunatomalacia. Radial shortening or ulnar lengthening?
In 35 patients with lunatomalacia, radial shortening (20 cases) was compared with ulnar lengthening (15 cases) 5 (1-14) years postoperatively. There was no radiographic evidence of recovery of the architecture of the lunate bone. The time of consolidation of the osteotomy with screw and plate fixation averaged 3 months after radial shortening and 4 months after ulnar lengthening. Pseudoarthrosis developed in 1 case of radial shortening and in 3 cases after ulnar lengthening. The two groups were equal with satisfactory results in two thirds of the patients.
