Minor tibial duplication: a new cause of congenital bowing of the tibia.
Five infants presented with a congenital anterolateral, unilateral bowing of the tibia. The fibula was normal but a bifid homolateral great toe was seen, associated with hand malformations. Plain films and CT disclosed a short tibial duplication, with distinct corticals. We do think that this abnormality represents a new entity, and may be related to a genetic anomaly. The long term follow up of our patients shows a spontaneously favourable prognosis without any association with pseudarthrosis. The only therapeutic problem is a limb length discrepancy.
