“Osteonecrosis is a disease resulting from the temporary or permanent loss of blood supply to the bones. Without blood, the bone tissue dies, and ultimately the bone may collapse. If the process involves the bones near a joint, it often leads to collapse of the joint surface. Osteonecrosis is also know as avascular necrosis, aseptic necrosis, and ischemic necrosis.
Although it can happen in any bone, osteonecrosis most commonly affects the ends (epiphysis) of the femur, the bone extending from the knee joint to the hip joint. Other common sites include the upper arm bone, knees, shoulders, and ankles. The disease may affect just one bone, more than one bone at the same time, or more than one bone at different times.” (The National Institute of Arthritis and Musculoskeltal and Skin Diseases)
HBOT has been shown to be an effective treatment of Avascular Hip Necrosis and other forms of Osteonecrosis.
