Congenital posteromedial bowing of the tibia (PMBT) is a rare deformity with limb length discrepancy (LLD) with or without significant angular deformity. Some patients need only limb length equalization while many patients require additional angular correction. Limb length equalization may be achieved by either limb lengthening, epiphysiodesis or acute shortening of the long leg. Limb lengthening is the preferred treatment option in PMBT patients with significant angular deformity. The presented study is to evaluate the results of lengthening with Ilizarov fixator in these patients. PMBT patients treated with Ilizarov lengthening were retrospectively reviewed. Progression of Limb lengthening with Ilizarov external fixator was performed in 4 PMBT patients. Mean age at surgery was 3.7 Ilizarov lengthening for posteromedial angulation shown good result with average residual LLD 0.4 to 1.4 cm which is not clinically significant.
