Revascularization of a partially necrotic talus with a vascularized bone graft from the iliac crest.

A 16-year-old patient had a compound dislocation of the right talus. Following primary treatment, which included a subtaler screw arthrodesis, the talus developed clinical, radiological, and isotope scan signs of necrosis. In spite of a walking caliper to prevent weight bearing on the ankle, the talar articular cartilage of the ankle joint also showed signs of degeneration. The talus was revascularized with a vascularized corticocancellous iliac crest bone graft. Six months postoperatively, there were clinical, radiological, and bone scan signs of significant revascularization. The patient is free of pain and able to walk with full weight bearing on the foot.
