What is Osteonecrosis?

Rate This

We all know what happens when your lungs lose their air supply, but what happens when your bones lose their blood supply? In a blood-compromised environment, your bones will die and eventually collapse. This is a condition known as osteonecrosis that can lead to pain and arthritis.

Osteonecrosis is commonly found in the upper leg, upper arm, knees, shoulders, and the ankles. Symptoms generally begin in their 30s – 50s, afflicting both men and women.

Also known as avascular necrosis, aseptic necrosis, and ischemic necrosis, osteonecrosis is the deterioration of bones and a decreased ability to rebuild bones. With healthy bones, your body continually replaces the old bone with new bone.

In the initial stages of the disease, you might not notice any symptoms at all. As the disease progresses, you may notice joint pain that worsens over time. Although the cause is unknown, the risk factors include the long-term use of steroids, injuries to the joints, excessive alcohol consumption, and the presence of other diseases, including cancer, lupus, and arthritis. Osteonecrosis can also affect individuals for no apparent reason at all.

To diagnose, your doctor will perform a complete physical assessment, take note of your medical history, and possibly order a certain diagnostic exam, such as an x-ray, MRI, CT scan, bone scan, or a bone biopsy. He may also want to measure the pressure inside of the bone.

When detected in its early stages, treatment is much more effective. To determine the best course of treatment action, your doctor will take into account your age, the stage of the disease, in which part of your body it is found, and the underlying cause, if known.

The main goals in treating osteonecrosis are to improve joint capability and to prevent any further damage to the affected area. It is imperative to continually protect the bones and joints. In the initial stages of the disease, a non-surgical approach will most likely be recommended.

Treatment options include the use of nonsteroidal anti-inflammatory medicines to alleviate the pain and swelling.

I have this disease and am more than open and happy to answer any questions or offer my support and knowledge to anyone that has any questions o interest in learning about it.

This disease is commonly referred to as AVN/ON - Avsacular Necrosis / Osteonecrosis

At the beginning of this article there is a list of places that are commonly effect; however, it did not include the hips. The hips are actually the most common joint that is hit with AVN/ON. Also, about 50% of patients with AVN/ON in the hips, shoulders, and knees have it bi-lateral (meaning both sides).
