Necrosis of the femoral head may be caused by alcohol abuse, so after the necrosis of the bone continues to drink alcohol may aggravate the necrosis of the bone, resulting in bone collapse or the opposite side of the femoral head will also appear necrosis, which will aggravate the condition. Therefore, patients with necrosis of the femoral head try to avoid drinking alcohol, which can affect the local blood circulation, and the change of local blood circulation is the pathological basis of necrosis of the femoral head, so it will aggravate the condition with the addition of triggering stimuli. The cerebellum of the body is anesthetized after alcohol abuse, and after anesthesia, the body movement is uncoordinated and unstable, which can easily lead to fall and fracture in the process. Therefore, if patients with osteonecrosis of the femoral head continue to drink alcohol, it will aggravate their condition, and in addition, it will also lead to fractures, so it is recommended to stay away from smoking and alcohol.
