A bone fissure is a type of fracture, clinically known as a hairline fracture. It refers to a situation where there is a crack in the cortical bone, but the stability of the bone is maintained. In cases of bone fissures, besides immobilizing and resting to reduce activity and prevent the worsening of fracture displacement, one should choose a diet rich in protein, calcium, phosphorus, and other trace elements. It is advised not to consume alcohol after a bone fissure, as alcohol needs to be metabolized by the liver, and the absorption and synthesis of trace elements like calcium and phosphorus also occur in the liver. Consuming alcohol can increase the burden on the liver and significantly impact the absorption of these inorganic ions, which is detrimental to the healing of the fracture, hence it is recommended not to drink alcohol after a bone fissure.
