Avascular necrosis of the scaphoid is known as?

Vascular compromise causing bone death in a wrist bone points to Preiser's disease. The scaphoid has a precarious blood supply, especially to its inner regions, so avascular necrosis can develop there, sometimes without a clear injury. Preiser's disease specifically describes idiopathic AVN of the scaphoid. As a contrast, Kohler disease is AVN of the navicular bone in the foot, Mueller-Weiss is AVN of the navicular in adults, and Monckeberg medial sclerosis is calcification of the arterial media, not a bone’s AVN.
