Congenital tibial dysplasia with lateral bowing and duplication of hallux: case presentations.

This article reports on two children with congenital unilateral tibial dysplasia with lateral bowing with no associated sagittal plane deformity. In both cases, it is associated with ipsilateral duplication of the hallux. Long-term follow-up of the patients showed spontaneous, almost complete resolution of the bowing without progressing into fracture or pseudoarthrosis. Leg length discrepancy appeared to be the only orthopedic sequela related to this phenomenon.
