A broken rib usually takes 3-5 weeks to recover, as follows: First, if it is a simple rib fracture, the fracture alignment and alignment are still acceptable, and the fracture can heal smoothly in 3-4 weeks after manual repositioning and bandage external fixation. Second, if a comminuted rib fracture occurs, the stability is usually poor, and even if fixation is used, the healing time will be prolonged accordingly, usually healing smoothly in 4-5 weeks. During fixation, the patient should insist on breathing exercises to avoid inflammation in the lungs, and also to accelerate blood circulation around the fracture to promote fracture healing and reduce tissue edema, as well as to relieve the irritating pain symptoms of the intercostal nerves. Through early diagnosis and early treatment, single rib fractures can be rapidly recovered.
