Optimizing the use of fibula in type II tibial hemimelia: early results.

Abstract

We describe a technique for optimal use of fibula in reconstruction of type II tibial hemimelia. Six affected children with mean age of 1.4 years and treated over a 5-year period were reviewed. All underwent staged reconstruction by lowering the fibula to below knee level using Ilizarov soft tissue distraction, transfer of distal fibula under proximal tibia, and foot centralization. Mean follow-up period was 3.6 years (range: 1.6-6.05 years). Mean age at follow-up was 4.4 years, and increase in length was 4.08 cm. Tibiofibular union and foot centralization were universally achieved. Mild residual equinovarus deformity was present in three children and braced. Our technique allowed significant length gain and foot centralization in toddlers without distraction osteogenesis.
