Patients with fractures should not drink white wine because alcohol can disrupt the microcirculation at the fracture site. Alcohol can make the small blood vessels at the fracture site constrict, or cause vasospasm and small local thrombosis, which can significantly reduce the blood supply to the fracture site. Sometimes the blood supply is even interrupted, which can slow down the formation of bone scabs and make fracture healing difficult, making it very easy to cause delayed healing or even non-union of the fracture. Alcohol should be banned during the healing period, which is three months after the fracture. Smoking is also prohibited, as it can disrupt the microcirculation of the fracture and affect the healing process. During this period, it is important to use a firm cast and eat a diet high in calcium to facilitate the growth and repair of the fracture.
