This article reviews the surgical treatment of talar avascular necrosis. Specifically, arthrodesis for this complex entity and potential treatment of nonunions are discussed. The hallmarks of treatment are evolving and can range from nonoperative measures to amputations. Nonoperative treatment and the results of current arthrodesis techniques for late-stage avascular necrosis are reviewed. Surgical correction requires an understanding of the condition's natural history, utilization of structural and nonstructural bone grafting techniques, and stable fixation. Although the methods described follow standard orthopedic principles, high-quality evidence and outcome studies are limited for treatment of this challenging and often disabling condition.
