Three patients with relative length discrepancy between the radius and ulna and with wrist angular deformity are reported. The Ilizarov apparatus was used for correction of the deformity by differential lengthening of the radius and ulna. The total lengthening percentages ranged from 21 to 52%. All patients obtained a good functional result after surgery with full range of motion of fingers and moderate loss of wrist range of motion in two patients. All patients were able to achieve primary bone healing.
