Ilizarov lengthening in centralized fibula.

Tibial hemimelia often produces major limb length problems (1,6,9,15) as well as foot deformity. The decision to perform reconstructive surgery depends on the expected leg-length discrepancy, the anomalies of the foot, and the status of the knee (4,6,8,15). Congenital bone deficiencies usually have a constant rate of growth inhibition (8), and leg lengthening is often associated with more complications (5,13). The complication rate is also increased with the increased leg-length discrepancy (5). In tibial hemimelia with functioning quadriceps (types I and II) and a functional foot, centralization of the fibula onto the talus and synostosis with the proximal tibia is an accepted reconstructive procedure (1,4,6,7,9,15). However, when the transplanted fibula produces a functional limb for the patient, the correction of leg-length inequality would be a challenge. This is a report of such a case.
