Avascular necrosis is clinically characterized by gradual onset of pain in motion and relieved by rest in affected joint. The pathophysiology of avascular necrosis has not been completely elucidated; whereas some cases of disease clearly have direct cause, the pathophysiology is uncertain for most cases. Avascular necrosis in Sheehan’s syndrome has not been described in published literature so for and may be due to disease state itself or to chronic corticosteroid therapy.
