What is the main cause of avascular necrosis?
Avascular necrosis is a disease that results from the temporary or permanent loss of blood supply to the bone. It happens most commonly in the ends of a long bone. Avascular necrosis may be the result of injury, use of medicines, or alcohol. Or it may occur after bone injury or bone surgery.
Is avascular necrosis serious?
Avascular necrosis is a localized death of bone as a result of local injury (trauma), drug side effects, or disease. This is a serious condition because the dead areas of bone do not function normally, are weakened, and can collapse.
What are the four 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).
Can avascular necrosis be cured?
There is no cure for avascular necrosis, but if it’s diagnosed early using X-rays or MRI, nonsurgical treatments such as activity modification, anti-inflammatory medications, injections, and physical therapy may slow its progression. Because avascular necrosis is a progressive condition, it often requires surgery.
Can you live with avascular necrosis?
The prognosis of AVN depends on the disease stage at the time of diagnosis and the presence of any underlying conditions. More than 50% of patients with AVN require surgical treatment within 3 years of diagnosis. Half of patients with subchondral collapse of the femoral head develop AVN in the contralateral hip.
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.
What foods are good for avascular necrosis?
Hence, include fruits and vegetables like oranges, grapefruit kiwi, guava, pineapple, strawberries, cauliflower, tomatoes, and bell peppers. Soya: Soya is also rich in omega-3 fatty acids that have inflammation fighting properties. Also it is low in fat, rich in protein and fiber, hence very good for overall health.
