General Discussion

Osteonecrosis is the destruction (necrosis) of bone tissue, often due to an interference with the supply of blood to the bone. It most commonly affects the joints and bones of the hips, knees and/or shoulders. It may occur as a result of bone injuries (trauma-related osteonecrosis) or in conjunction with other diseases or risk factors (nontraumatic osteonecrosis). Risk factors include excessive alcohol intake, some blood coagulation disorders, inflammatory conditions such as rheumatoid arthritis and systemic lupus erythematosus, and reactions to some medications such as steroids.
