Incidence and pathogenesis of alcohol-induced osteonecrosis of the femoral head.
Anteroposterior pelvic roentgenograms of 790 patients admitted for treatment of alcoholism were examined for evidence of osteonecrosis of the femoral head. Laboratory data on these patients, obtained shortly after admission, demonstrated that average serum cholesterol levels were within normal limits and average serum triglyceride levels were moderately elevated only in those individuals classified as having a severe addition to alcohol. Non-juxta-articular radiographic abnormalities of the femoral head, neck and shaft were common but no changes were observed which were considered to be early indications of structural insufficiency. Two patients had advanced idiopathic bilateral osteonecrosis of the femoral head. One of these patients had undergone one total hip replacement prior to his current admission. This study indicates that there is a very low incidence of osteonecrosis among alcoholics (less than 0.3%). However, alcoholism may lead to osteonecrosis in certain predisposed individuals. A combination of several factors such as systemic fat embolism, elevated circulating levels of inflammatory fatty acids or prostaglandins, and osteoporosis and Charcot-like effects, which are also associated with corticosteroid-induced osteonecrosis, seem to be involved and may contribute, as well, to other instances of femoral head osteonecrosis.
