Dexamethasone-Induced Avascular Necrosis of the Femoral Head in a Patient With Major Depressive Disorder: A Rare Case Report.

Avascular necrosis (AVN) of the femoral head, also known as osteonecrosis, is one of the main causes of disability during the most productive years of life and results in significant financial consequences. This condition most commonly occurs in patients with long-term and inappropriate corticosteroid use, particularly dexamethasone. This is a rare case report of AVN and steroid-induced depression in a patient who was wrongly advised by peers to administer dexamethasone to counteract the physical decline associated with chronic substance use. This case highlights the necessity of regular screening for corticosteroid misuse in patients with chronic substance use and highlights the need to develop preventive approaches.
