Bone part that undergoes necrosis in alcoholics is

  1. Head of femur

  2. Shaft of femur

  3. Vertebrae

  4. Carpals
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Alcoholic persons suffer from a disease of necrosis of bone called osteonecrosis or avascular necrosis. It is the death of bone tissue due to which head of femur collapse.
