What is avascular necrosis of the hip?

Bone death collaps: Avascular necrosis is the death of bone tissue due to a lack of blood supply. Also called osteonecrosis, avascular necrosis can lead to tiny breaks in the bone and the bone's eventual collapse.

Hip joint breakdown: Avascular necrosis represents a spectrum of issues that advance from mild hip pain early in the process and heads toward varying degrees of femoral head collapse and severe pain with limited function. Speak to your orthopaedic surgeon if you are having progressive hip pain to see if imaging with X-rays or an MRI is indicated
