Avascular necrosis (AVN), also called osteonecrosis, refers to bone tissue death caused by a loss of blood supply to the tissue. AVN most commonly affects the joints in the hips, shoulders, knees, hands, and ankles. Many conditions can increase the risk of developing AVN, such as:
- Autoimmune disorders, such as rheumatoid arthritis, lupus, or HIV/AIDs
- Blockages in the arteries and blood vessels
- Damage from broken bones or dislocated joints
Smoking, severe alcohol use, and excessive corticosteroid use are other causes.
AVN is a progressive condition, which means it gets worse over time. Left untreated, it causes the bone to weaken and eventually collapse. The main symptom in avascular necrosis is pain when you put weight on the affected joint, which eventually leads to constant pain, even at rest.
Treating AVN focuses on reducing pain, slowing bone damage, and improving lost function. Because it’s a progressive condition, most people with AVN require orthopedic surgery.
