Ankle reconstruction and lengthening strategy in type II fibular hemimelia: a report of two cases.

Limb lengthening of fibular hemimelia is associated with progressive ankle valgus deformity. We reported a successful tibial lengthening in fibular hemimelia without recurrence of ankle valgus in 2 cases. The procedure involved 2 stages. First stage was a resection of the fibular remnant followed by a bending osteotomy through the distal tibial physis before the age of 2 years old. The second stage was a tibia lengthening up to 25% of its original segmental length performed at the age of 5 years old. There was neither progressive ankle valgus nor distal tibial growth arrest observed at 4 years follow-up.
