What is osteonecrosis?

osteonecrosis refers to the death of part of bone tissue, which is the result of injury, illness or clot that prevents new blood from reaching bone. Without blood, bone cells do not get enough oxygen or nutrients to be successful. The affected bone eventually becomes fragile and disintegrates. Doctors usually treat the condition of surgically by renewing blood supply and grafting healthy bone tissue on the damaged joint. In surgical treatment and subsequent physical therapy, patients are usually able to regain most of their strength and extent of movement.

Any bone in the body can potentially be influenced by osteonecrosis, although the main joints are most sensitive. Most cases include femoral bones in the hip, tibia in the knee or humerus in the shoulder. Symptoms usually do not occur in the earliest stages of osteonecrosis. As more tissue dies, the individual may notice that his joint is pyrier after physical activity than usual. Despite the monsters of the months, the joint can cause constant pain and be gentle on dotEC. The condition leads to a limited range of movement and eventually leaves the joint unable to move at all.

Blood can be cut off from bone due to trauma, such as fracture or dislocation, or a disease that affects blood flow such as clotting disorder or sickle anemia. Research also suggests that long -term smoking and alcohol use can expose people to higher risk of developing osteonecrosis, as such activities affect blood pressure and circulation. Osteonecrosis is most commonly seen in people who are 30 to 60 years old.

An individual who has chronic joint pain should see a doctor to be projected on osteonecrosis and other potentially serious conditions. The physician can make a diagnosis by asking the patient for symptoms, physically examining the joint and tacentgen rays. The death of bone cells can be clearly seen in X -ray images and the doctor uses scan to determine the severity of the hundredvu.

After the diagnosis, the physician establishes a decision to treat the basic cause. If it is clear that healing diseases cause bone problems, patients are usually given medication and equipped with crutches or braces that help keep the weight out of the joint until they heal. Most cases of osteonecrosis, especially bone -related cases, require surgery to avoid serious future complications. The surgeon may decide to cut off damaged tissue, break a blood clot or make a large bone graft. In the event of severe joint damage, the surgeon could completely remove it and replace it with artificial joint.
