Avascular necrosis, commonly known as osteonecrosis, is a condition in which the bones and joints lose their blood supply and eventually die. Unfortunately, avascular necrosis cannot be cured and usually does not go away on its own. However, with early diagnosis and prompt treatment, the progression of the disease can be slowed down and the symptoms managed.
Causes of Avascular Necrosis
Avascular necrosis is caused by a disruption in the blood supply to the bones. This can be caused by a traumatic injury, such as a fracture or dislocation, or by a medical condition, such as osteoarthritis, lupus, or sickle cell anemia. Other possible causes include long-term use of steroids, alcohol abuse, and radiation therapy.
Diagnosis of Avascular Necrosis
Avascular necrosis is usually diagnosed with an X-ray or MRI scan. These imaging tests can reveal areas of bone death and help the doctor determine the extent of the damage. In some cases, a biopsy may be necessary to confirm the diagnosis.
Treatment of Avascular Necrosis
The goal of treatment for avascular necrosis is to reduce pain and slow the progression of the disease. Treatment may include medication to reduce inflammation, physical therapy, and lifestyle changes such as avoiding activities that put stress on the affected joint. In some cases, surgery may be necessary to replace the affected joint.
Although avascular necrosis cannot be cured, early diagnosis and prompt treatment can help slow the progression of the disease and reduce the pain and disability associated with it.
