Avascular necrosis of the talar dome is known as?

Avascular necrosis happens when the blood supply to a bone is disrupted, causing bone tissue to die and the structure to weaken. When this process involves the talar dome, the condition has been described in older medical literature as Diaz disease. The talus relies on small, fragile blood vessels, so injury or ischemia can lead to necrosis specifically in the dome area, producing the characteristic pain and potential joint problems you’d expect from AVN of the talus. This term is distinct from other bone or vascular conditions, like Monckeberg medial sclerosis (arterial calcification), Sever disease (calcaneal apophysitis), or conditions named for other bones (such as Kohler’s disease for the navicular). So the talar dome AVN is Diaz disease.
