Avascular necrosis (AVN) is a condition in which one or more of the bones in the body (usually the hip or shoulder) develop a lack of blood supply, leading to tissue death and eventual bone collapse. As a result, the affected bone becomes weak and prone to fractures.
The good news is that AVN can be stopped in its early stages. If caught early enough, the condition can be treated with medications such as non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids to reduce pain and swelling. In more advanced cases, a surgical procedure called core decompression may be necessary to restore blood flow to the affected bone. This procedure involves removing a small portion of the bone and then filling the resulting cavity with bone graft material to stimulate the growth of new healthy bone tissue.
In addition to medical treatment, lifestyle modifications are also important in managing AVN. Weight-bearing activities should be avoided, as they can put additional strain on the affected bone, and patients should maintain a healthy diet and exercise regularly to reduce the risk of developing the condition. It is also important to limit the use of alcohol and tobacco, as these substances can interfere with the healing process.
Finally, it is important to note that AVN is a progressive condition and, if left untreated, can lead to disability, so it is important to seek medical attention as soon as you experience any symptoms. Early diagnosis and treatment are key to preventing the condition from progressing any further.
