Incomplete fracture of three ribs is not very serious, the stability of the fracture is relatively good, and active conservative treatment can be carried out. Incomplete fracture of ribs means that the external force did not cause the breakage of all the bone cortex at the injury site, but only part of the bone cortex continuity is interrupted, and part of the bone cortex is still intact. Incomplete fractures, also known as cleavage fractures, are characterized by a lack of displacement of the fracture site and the ability to maintain normal anatomical relationships. The fracture is relatively stable and will not dislocate if no further force is applied. Incomplete fractures also recover relatively quickly, and the limb should be immobilized with a brace or cast as soon as possible after the fracture, so as not to cause the incomplete fracture to continue to be subjected to external forces and become a complete fracture, with displacement of the fracture. After 4 to 6 weeks of external immobilization with rib fixation straps or chest straps, the condition will be more stable. During this period, deep breathing exercises for lung function are performed and medications to promote fracture healing are taken. If you feel unwell, you can go to the hospital for an X-ray to prevent displacement of the fracture.
