    No full text
    Osteonecrosis of the talus (ONT) refers to the death of osteocytes and subsequent structural changes leading to talus collapse and secondary ankle joint osteoarthritis. ONT is a rarer disease than osteonecrosis of the femoral head (ONFH); however it is a signifi cant clinical challenge with an uncertain long-term prognosis [ 1, 2 ]. In this chapter, we review osteonecrosis of the talus, describing incidence and etiology, blood supply, clinical presentation, diagnostic imaging, classifi cation, and treatment.N
