Alcohol consumption has a close relationship with femoral head necrosis, in the three major causes of femoral head necrosis, drinking occupies an important position, that is, the chances of femoral head necrosis occurring in people who drink a lot of alcohol or alcoholism for a long time are several times higher than normal people, especially alcohol addiction, the chances of femoral head necrosis occurring in patients who drink more than 0.5 kg per day and drink for more than 10 years increase exponentially. What causes drinking can cause femoral head necrosis is currently believed to be the lipid metabolism theory. Drinking affects the metabolism of liver lipids, resulting in elevated lipids in the blood, and elevated lipids in the blood will be sticky and poorly mobile, leading to reduced blood supply to the femoral head, which in turn leads to femoral head necrosis. Therefore, alcoholics are advised to quit drinking as much as possible, and patients with osteonecrosis of the femur should quit drinking as a priority.
