A fracture of the posterior rib will heal in about 8 to 12 weeks. Rear rib fracture needs to be based on whether the fracture has damaged other organs or tissues, if there is no damage to other organs or tissues, conservative treatment can be used, due to the fact that each rib has upper and lower two sets of blood supply, the blood supply is more abundant, the recovery speed is relatively fast, usually in 8~12 weeks to recover and heal. If the rib is fractured and there is injury to internal organs such as kidneys, spleen, lungs, etc., then surgical treatment is needed to protect the internal organs and restore the continuity of the ribs, in which case the ribs may need a longer recovery time, usually more than 12 weeks. It is recommended to follow the doctor’s instructions to carry out appropriate rehabilitation exercises to promote fracture healing, and at the same time, to carry out the relevant review on time to understand the recovery situation.
