Also known as osteonecrosis, avascular necrosis is the death of bone from interruption of blood supply. This can result in tiny bone fractures and eventual destruction of the entire bone. It can be caused by trauma, blockage of circulation with lipids in the blood, certain diseases like sickle cell disease, Gaucher, and occasionally after exposure to corticosteroids. Sometimes, there ...Read more

Are early cystic changes on navicular bone many months post injury a sign of avascular necrosis?

Cysts in bone: Cystic changes or erosions in bone post trauma can indicate that the bone matrix was disrupted from the injury and cystic changes have resulted. It does not mean that you have avascular necrosis, but it can mean that there are changes in the trabecular patterns of the bone due to the trauma. Bone injuries can cause many different bone patterns to occur as a result of the bone trying to heal itsel ...Read more

Avascular necrosis: Marrow edema, like swelling anywhere else in the body, is a nonspecific response to any number of inflammatory, infectious, traumatic, vascular, autoimmune, arthritic, or neoplastic processes.

Can nicotine cause avascular necrosis as it constricts blood vessels? I know it stopped my recent bone graft in a spinal fusion from growing properly.

Can nicotine cause avascular necrosis as it constricts blood vessels? I know it stopped my recent bone graft in a spinal fusion from growing properly.

Maybe: Smoking is well-known to impair new blood vessel growth into areas of bone fusion and prevent good healing. There are thousands of chemicals in smoke. Nicotine alone has been well studied and tends to show poor bone formation and mineralization. So using nicotine as a supplement instead of smoking still is a risk for your spinal fusion. You have one spine -- take good care! Good Luck! ...Read more
