GENERAL HISTOLOGY

Detailed explanation-1: -Avascular necrosis is the death of bone tissue due to a lack of blood supply. Also called osteonecrosis, it can lead to tiny breaks in the bone and cause the bone to collapse. The process usually takes months to years. A broken bone or dislocated joint can stop the blood flow to a section of bone.

Detailed explanation-2: -Avascular necrosis (AVN) is the death of bone tissue due to a loss of blood supply. You might also hear it called osteonecrosis, aseptic necrosis, or ischemic bone necrosis. If it isn’t treated, AVN can cause the bone to collapse.

Detailed explanation-3: -What is Avascular Tissue? Tissues that do not contain blood vessels or lymphatic system are referred to as avascular tissues. Examples of avascular tissue include epithelial cells, cornea of the eye and cartilage.
