Cubitus varus and valgus are the most common complications of supracondylar and lateral condylar fractures. Various combinations of osteotomy and fixation have been described to correct these deformities but each is associated with significant complications. In this study, we used distraction osteogenesis and Ilizarov frame fixation to treat 24 elbows in 23 patients with cubitus varus or valgus. Their clinical outcome was evaluated using the protocol of Bellemore et al. The mean time to follow-up was 18.3 months (10 to 36) and the mean time to frame removal was 13.5 weeks (8 to 20). The mean carrying angle was corrected from -18.7 degrees (-10 degrees to -30 degrees) to 6.1 degrees (2 degrees to 10 degrees) in patients with cubitus varus and from 36.5 degrees (25 degrees to 45 degrees) to 9.4 degrees (4 degrees to 15 degrees) in patients with cubitus valgus. There were 18 excellent and six good results.
