Abstract

The treatment of anterolateral bowing with an intact tibia is directed toward prevention of the fracture and subsequent pseudoarthrosis. Patients with anterolateral bowing of the tibia are usually treated with an ankle-foot orthosis until the deformity is improved. There is no documentation that an orthosis can prevent the fracture or correct the deformity, and if the deformity is not corrected, it will result in different mechanical problems. In this study, 6 legs in 6 patients with anterolateral bowing of the tibia with a narrow sclerotic medullary canal (Crawford type II) were treated using Ilizarov's method. The average age was 6.8 years. All patients underwent correction of the anterolateral bowing by excision of the affected part. If the gap was less than 4 cm, acute shortening followed by bone lengthening was done. If the gap was more than 4 cm, bone transport was preferred. The mean duration of follow-up was 3.2 years. The anterolateral bowing was corrected in all patients. Complications such as pin track infection, premature consolidation and delayed union at the docking site were encountered. We believe that Ilizarov's method offers a more efficient solution for this type of deformity than prophylactic orthotic treatment or prophylactic bypass bone graft.
