Background:Thromboangiitis obliterans (TAO), also known as Buerger disease, is characterized by thrombosis in medium-sized arteries and veins along with a marked inflammatory response. TAO can be managed by using the principle of distraction osteogenesis to induce neoangiogenesis. We report thirty patients of TAO in the age-group of 20–50 years were treated with the Ilizarov method.Materials and Methods:Patients with severe rest pain (n=30), absent distal pulsation (n=30) and ulcer (n=6) and/or gangrene of the toes (n=4), who had failed the conservative pharmacological modalities of treatment were included. A lateral tibial corticotomy was performed and distraction applied by use of olive wire. A two-ring frame was used for all cases.Results:Of the 30 cases, 25 patients became pain free while 1 had partial relief of pain. The four patients worsened on treatment and developed frank infection were amputed. The average distraction was 1.8±0.3 mm (range: 1.5–2.2 cm). The mean consolidation period was 98±11 days, after which the fixator was removed. The total duration of treatment was 122±23 days. There were two cases of osteomyelitis in our series; both healed after debridement and both patients had good result, with relief of pain. The ulcers started healing by 4–6 weeks.Conclusion:The principle of the distraction osteogenesis including neoangiogenesis can be used for treatment of TAO and has an acceptable complication rate.
