We evaluated the results of treatment with the Ilizarov circular external fixator for limb length inequality and deformities in patients with type IA, IB, and type II fibular hemimelia.
Tibial corticotomy and distraction osteogenesis with the Ilizarov technique were performed in five male patients (mean age 11.4 years; range 4 to 20 years). According to the classification of Achterman and Kalamchi, fibular hemimelia was type IA, IB, and II in three patients, one patient, and one patient, respectively. Involvement was on the right in three patients, and on the left in two patients. Two patients had equinus and one patient had valgus deformities. No instability existed in the ankle and knee joints. The mean leg discrepancy was 8.7 cm (range 3 to 16.5 cm), and the mean lengthening index was 1.6 cm/month (range 1.4 to 2 cm). The mean follow-up was 33 months (range 15 to 68 months).
On final examinations, full range of motion of the knee was obtained. A plantigrade foot was achieved in three feet, while two sustained an equinus deformity of 17 and 15 degrees, respectively. Pin tract infections were observed in four patients, all of which were treated with oral antibiotics and dressing. During distraction, three patients had pain. Two patients had a limited range of motion of the ankle joint, without instability or subluxation of the ankle and knee joints. These joint problems were successfully dealt with by physical exercises.
The Ilizarov technique is a convenient method in the correction of angular and rotational deformities while enabling distraction in type I and type II fibular hemimelia.
