Correction of Madelung's deformity by the Ilizarov technique.

We present our experience with correction of Madelung's deformity by the Ilizarov technique. Seven patients (eight deformities) were treated by osteotomy of the radius with subsequent lengthening and angular correction. They were reviewed at a mean of 30 months (1.5 to 5.5 years). At the time of operation their mean age was 19 years (9 to 44). At follow-up all were free from pain and supination had improved by a mean of 34 degrees and pronation by 9 degrees. Flexion had increased in most cases with a median increase of 15 degrees, but only one patient gained further extension. Radial and ulnar deviation were increased by a mean of 6 degrees and 9 degrees, respectively. Radiographic measurements showed that the mean volar angulation had been reduced from 25 degrees to 11 degrees, ulnar inclination from 45 degrees to 30 degrees and carpal malalignment (volar translation) from 7 to 2 mm. The mean lengthening of the radius was 12 mm (6 to 25). All the patients were satisfied with the functional and cosmetic results.
