overview
Avascular necrosis is the death of bone tissue due to a lack of blood supply. Also called osteonecrosis, it can lead to tiny fractures and ultimately to bone collapse.Avascular necrosis Treatment Hyderabad
- A broken bone or a dislocated joint can cut blood flow to a section of bone. Avascular necrosis is also linked to long-term use of high-dose steroids and excessive alcohol consumption.
- Anyone can be affected, but the disease is more common in people between the ages of 30 and 50.
symptom
Many people have no symptoms in the early stages of avascular necrosis. If the condition worsens, the only way to hurt your affected joint is to put weight on it. After all, you may feel pain even when you lie down.
- The pain can be mild or severe and usually develops gradually. Pain associated with avascular necrosis of the hip may focus in the groin, thighs, or buttocks. In addition to the hip, the shoulder, knee, hand, and foot are likely to be affected.Avascular necrosis Treatment Hyderabad
- Some people develop avascular necrosis on both sides (bilaterally) – for example, in both hips or both knees.
The reasons
Avascular necrosis occurs when blood flow to a bone is interrupted or decreased. A decreased blood supply can be caused by:
- Joint or bone trauma. An injury such as A joint dislocation, for example, can damage nearby blood vessels. Cancer treatments can also weaken bones and damage radiation blood vessels.
- Fat deposits in the blood vessels. Fat (lipids) can block small blood vessels and reduce blood flow to the bones.
- Some diseases. Conditions such as sickle cell anemia and Gaucher’s disease can also lead to decreased blood flow to the bones.
Risk factors
Risk factors for developing avascular necrosis include:
- Trauma. Injuries such as a dislocation or fracture of the hip can damage nearby blood vessels and reduce blood flow to the bones.Avascular necrosis Treatment Hyderabad
- Use of steroids. The use of high-dose corticosteroids such as prednisone is a common cause of avascular necrosis. The reason is unknown, but one hypothesis is that corticosteroids may increase the levels of lipids in your blood, thereby decreasing blood flow.
- Excessive consumption of alcohol. If you have consumed several alcoholic beverages a day for several years, fat deposits can also form in your blood vessels.
- Use of bisphosphonate. Long-term use of drugs to increase bone density can contribute to the development of osteonecrosis of the jaw. This rare complication has occurred in some people treated with high doses of these drugs for cancers such as multiple myeloma and metastatic breast cancer.
- Certain medical treatments. Radiation therapy for cancer can weaken bones. Organ transplant, particularly kidney transplant, is also associated with avascular necrosis.
prevention
To reduce your risk of avascular necrosis and improve your overall health:
- Limit your alcohol consumption. Excessive alcohol consumption is one of the main risk factors for developing avascular necrosis.
- Keep your cholesterol low. Tiny lumps of fat are the most common substance that blocks blood supply to the bones.
- Monitor steroid use. Make sure your doctor is aware of your past or current use of high-dose steroids. Steroid-related bone damage appears to work with repeated high-dose steroid treatments.
- Do not smoke. Smoking increases the risk.Avascular necrosis Treatment Hyderabad
