What Is Aseptic Osteonecrosis?

Aseptic necrosis, also known as osteonecrosis, is a serious condition affecting the bones. If not treated properly, it can lead to bone damage and even the collapse of the bone.

What is Aseptic Necrosis?

• Aseptic necrosis is a condition where part of a bone does not receive blood and dies. Over time, if it is not treated, bone damage can get worse and eventually the bone can break off.

What are the Causes?

• Aseptic necrosis is mainly caused by either disease or severe trauma. Diseases such as sickle cell and Gaucher disease have been associated with causing aseptic necrosis. The severe trauma of a bone break or dislocation can also be a cause.

Symptoms

• As bone damage worsens, symptoms may appear. The most notable symptoms will include pain in the joint and limited range of motion.

Diagnosis

• A physician will complete a physical exam and ask you questions about your condition. Following that, you will most likely undergo tests including X-ray, MRI, bone scan, and CT scan in order to determine a diagnosis.

Treatment

• In order to slow the progression of aseptic necrosis, you can take pain relievers and limit the use of the affected area. However, surgery options, including bone grafts and joint replacement, are common treatments to completely alleviate the condition.
