At Orthopedics and Joint Replacement at Mercy Medical Center in Baltimore, Maryland, our orthopedic surgeons specialize in joint preservation and reconstruction. Patients from across the Baltimore region seek the expertise of our doctors for their advanced skills in treating avascular necrosis of the hip and knee.
Avascular necrosis is a condition in which a portion of bone dies due to loss of blood supply. When blood flow to the bone is disrupted, the bone begins to fracture and eventually can collapse. Blood flow to bones can be disrupted due to trauma, joint dislocation or pressure in the bone due to medical conditions such as sickle cell anemia, lupus or Gaucher’s disease.
Certain medications, such as steroids, and excessive drinking can cause fat to build in the blood preventing the blood from reaching the bones. Avascular necrosis most commonly affects the hip, but also can affect the knee, shoulder, hand and foot.
Avascular necrosis initially may not cause any symptoms. As avascular necrosis develops, joints may begin to hurt with activity and eventually even while inactive. Symptoms of avascular necrosis can include:
Orthopedic surgeons diagnose avascular necrosis by first performing a physical exam. The painful joint is examined by the orthopedic surgeon while it is moved to test for range of motion. Imaging tests such as X-rays, bone scans and MRIs may be conducted to look for changes in bone structure.
Initial treatment for avascular necrosis includes:
