📋Overview
Avascular necrosis (AVN), also known as osteonecrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. This leads to bone collapse and joint damage if untreated. The term 'avascular necrosis' is the preferred modern terminology, with 'osteonecrosis' used interchangeably. It most commonly affects the hip but can involve other bones.
