Avascular necrosis is a condition that develops when blood supply to the bones is cut off. This section of the eMedTV archives explains this condition in detail, including causes, symptoms, treatment options, and more.
Avascular necrosis is due to either traumatic or nontraumatic causes. This eMedTV segment explains these causes of avascular necrosis in detail (such as steroid use or injury to a joint) and also includes possible risk factors.
Possible avascular necrosis symptoms include osteoarthritis, limited range of motion, and joint pain (the most common). This page of the eMedTV website discusses avascular necrosis symptoms and explains why they vary from patient to patient.
Pain is not often felt in the early stages of avascular necrosis. This page of the eMedTV Web site explains how the pain worsens as the condition becomes more severe and describes methods used to treat pain with avascular necrosis.
Tests used in making an avascular necrosis diagnosis include MRI scans, CT scans, x-rays, biopsies, and more. This section of the eMedTV website explains the tests used to make an avascular necrosis diagnosis.
As this eMedTV segment explains, treating avascular necrosis may involve medications, exercises, surgery, or other options. This article explains the treatment options in detail, including when each type is generally used.
Avascular necrosis research studies test ways to diagnose the disease earlier and new and improved treatment methods. This eMedTV article explains these avascular necrosis research studies, including potential benefits for research participants.
