After a rib fracture, there is a period of bone scab formation about a month after the fracture. This must be based on the successful healing of the fracture site, as there is a time limit for fracture recovery. Two weeks after the rib fracture, the blood clot located at the broken end of the fracture gradually aggravates to form a scab, after which a fibrous connection is made at the fracture site. It is only after four weeks or so that the connections at the fracture site of the rib gradually evolve into a primitive bone scab. So it takes four weeks, or about a month, for a rib fracture to form a scab. Therefore, it is very important to protect the fracture in the early stage after the fracture, after the fracture, we should pay attention to protect the fracture site, to prevent the fracture end from re-exposure to force or stress concentration, and to avoid collision to avoid causing secondary injury. In the case of a normal diet, supplemented with vitamins or calcium preparations, at the same time in the diet and routine should pay attention to strengthen the nutrition, as soon as possible to carry out rehabilitation exercises, through these measures to help prevent lung infection and other complications. After a rib fracture, the fracture can be shaped gradually to the state before the fracture in about three months, and the surface of the fractured part is smooth and clean.
