Osteonecrosis, also known as avascular necrosis, is a condition that affects the hip joint of the body. It happens when the blood supply to the bone is disrupted, leading to the death of the bone tissue. The condition can occur at any age, but is most common in adults between the ages of 30 and 50.
What Causes Osteonecrosis in the Hip?
Osteonecrosis of the hip can be caused by a variety of factors, including trauma, medical conditions, and certain medications. Trauma, such as from a fall or a direct blow to the hip, can cause the blood supply to be disrupted, leading to the death of the bone tissue. Medical conditions, such as lupus or sickle-cell anemia, can also cause the condition. Certain medications, such as steroids, can also lead to the death of the bone tissue in the hip.
