Sixty-nine lower extremities of 45 patients (mean age, 10 years 8 months) with tibia vara were treated with the Ilizarov circular external fixator and distraction osteogenesis. Twenty-four of the patients had bilateral involvement, six of whom had simultaneous surgery and the remaining 18 had staged operations 8 to 12 months apart. In 11 limbs with femoral valgus deformity greater than 10 degrees simultaneous corrections were done. Active movements of the joints of the extremity were encouraged the day after surgery and partial weightbearing began 2 days later. All patients were followed up 27 to 178 months (mean, 80 months) after surgery. No neurovascular complications, delayed union, or nonunions were observed. The mean 28.6 degrees varus tibiofemoral angle preoperatively (range, 15 degrees -45 degrees ) improved to 7.5 degrees valgus (range, 0 degrees -18 degrees ) postoperatively. The preoperative internal torsion angle also improved from 20.7 degrees (range, 0 degrees -48 degrees ) to 3.5 degrees external torsion (range, 0 degrees -9 degrees ) postoperatively. Residual deformity was seen in six patients, and they had successful revision surgery using the same technique. The Ilizarov method allows early weightbearing and motion and allows all components of the deformity to be corrected.

Seven children with a post-traumatic cubitus varus deformity were treated using the Ilizarov technique of distraction osteogenesis. The outcome was rated as excellent in each case and all were satisfied with the cosmetic appearance. No complications had been encountered by the latest follow-up at a mean of 66.7 months. This technique seems reliable for the treatment of such deformities, provided that it achieves full correction by gradual distraction. Nerve palsy and unsightly scars are avoided, and the range of movement of adjacent joints is preserved.

Patients with short congenital amputations below the elbow often function as if they have had a disarticulation of the elbow. We have reviewed the results in six patients who had lengthening of such stumps by the Ilizarov technique to improve the fitting of prostheses.The mean lengthening was 5.6 cm (3.4 to 8.4), and in two patients flexion contractures of the elbows were corrected simultaneously. Additional lateral distraction was used in one patient to provide a better surface on the stump. There were no major complications. All six patients were able to use their prosthesis at the latest follow-up after 39 to 78 months.
