Avascular necrosis of the humeral head is known as?

Avascular necrosis is bone death caused by a disrupted blood supply, and when it involves the humeral head, it is classically named Hass disease. This term identifies the shoulder’s osteonecrosis specifically, distinguishing it from AVN in other bones or from unrelated vascular conditions. The other options refer to different parts of the body or entirely different conditions (for example, Monckeberg medial sclerosis is arterial calcification, Mueller-Weiss syndrome affects the navicular bone in the foot), so they don’t describe the humeral head AVN.
