What is a dead bone?

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 the bone’s eventual collapse. A broken bone or dislocated joint can interrupt the blood flow to a section of bone.

How do you treat a dead bone?

The options include:

Core decompression. The surgeon removes part of the inner layer of your bone.
Bone transplant (graft). This procedure can help strengthen the area of bone affected by avascular necrosis.
Bone reshaping (osteotomy).
Joint replacement.
Regenerative medicine treatment.

Can dead bone regenerate?

This is a series of clinical case reports demonstrating that a combination of percutaneously injected autologous adipose-tissue-derived stem cells, hyaluronic acid, platelet rich plasma and calcium chloride may be able to regenerate bones in human osteonecrosis, and with addition of a very low dose of dexamethasone.

What happens when you have a dead bone?

After a while, the bone can collapse. If osteonecrosis is not treated, the joint deteriorates, leading to severe arthritis. Osteonecrosis can be caused by disease or by severe trauma, such as a fracture or dislocation, that affects the blood supply to the bone. Osteonecrosis can also occur without trauma or disease.

Is bone death painful?

Avascular necrosis is a painful bone condition that gets worse over time and can affect your mobility. It occurs when something cuts off blood flow to one of your bones. Causes include broken bones, dislocated hips, radiation therapy and alcohol misuse.

What are the 4 stages of avascular necrosis?

Stage 1 has a normal x-rays but MRI reveals the dead bone. Stage 2 can be seen on regular x-ray but there is no collapse of the femoral ball. Stage 3 shows signs of collapse (called a crescent sign) on x-ray. Stage 4 has collapse on x-ray and signs of cartilage damage (osteoarthritis).

What is osteonecrosis pain like?

Osteonecrosis develops in stages. Hip pain is typically the first symptom. This may lead to a dull ache or throbbing pain in the groin or buttock area. As the disease progresses, it becomes more difficult to stand and put weight on the affected hip, and moving the hip joint is painful.

Is bone death curable?

There is no cure, so the main goal of treating osteonecrosis is to slow down the deterioration of the bone. Most nonsurgical treatments are not a long-term solution.

What does bone death feel like?

Symptoms may include: Minimal early joint pain. Increased joint pain as bone and joint begin to collapse. Limited range of motion due to pain.
