Whether rib fracture will heal abnormally if treated conservatively is mostly related to the degree of fracture and fixation time, etc. Mild rib fracture (e.g., bone fracture) generally will not heal abnormally if treated conservatively, while severe rib fracture may lead to abnormal healing if treated conservatively. Malunion of rib fractures is due to poor fracture repositioning, poor fixation or short fixation time after fracture injury, and the influence of muscle pulling, body weight and inappropriate weight bearing. Mild rib fractures (e.g. bone fracture) have no or less displacement of the broken end, and can be treated well with conservative treatment, and generally do not undergo malunion. Severe rib fractures such as comminuted rib fractures often require surgical incision and internal fixation. Conservative treatment may lead to poor fracture repositioning resulting in dislocation or angular deformity of the rib fracture, etc. Generally, mild cases do not affect respiratory function and do not require special treatment. If the symptoms are severe enough to affect respiratory function, surgery is often needed. After the rib fracture, you should go to the hospital as soon as possible, follow the doctor’s advice, strictly standardize the treatment, and have regular checkups to prevent deformed healing or non-healing.
