The ribs are not regenerative, in this case the bone defect is not restored after the complete removal of the ribs or the internal cartilage, the rib area loses its ability to continue to grow after the end of growth. If a part of the rib is removed, no recovery will be obtained due to the very poor ability of the rib cartilage to regenerate. If a rib fracture occurs, it is possible for the fractured end to heal with appropriate conservative or surgical treatment, but this healing is not regeneration of the rib. In short, once a rib has been defective, it cannot regenerate.
