Nine rib fractures usually take about six months to heal. However, you need to pay attention to whether there is any injury to the thoracic and abdominal organs in the lower chest fracture, once the injury is external force is relatively large, which can cause damage to the thoracic and abdominal organs. Therefore, attention should be paid to CT to check whether there are combined injuries to the lungs, liver and gallbladder, and kidneys. Therefore, in daily life work, attention should be paid to avoid heavier direct external force injuries. In the late stage of rib fracture, proper exercise is also essential to speed up the deposition of calcium and the recovery of the fractured severed end. In case of multiple bone fractures, they are usually not very serious as long as they are not combined with injuries to the thoracic and abdominal organs. However, it is still important to note that the activity level should be reduced, the diet should be strengthened, and the functional exercise should be enhanced in general. The pain will be significantly reduced in about two weeks, and the fracture site will have a fibrous connection, and after it is relatively stable, you can gradually carry out restorative activities, and there will usually be significant scab growth at the fracture site in about six to eight weeks, and the fracture end will be completely healed in about six months. Therefore, multiple ribs can be fully recovered in about six months, at which time they can resume their normal work life.
