An open, randomized, parallel controlled prospective clinical study design type was used in this study. Subjects were patients with two to four displaced non-flail chest fractures of the ribs. Operation group (Group 1) : minimally invasive internal fixation operation group under spontaneous breathing anesthesia. In the operation group of minimally invasive internal fixation under autonomic respiratory anesthesia, the fracture was determined preoperatively by chest CT+ three-dimensional reconstruction of the ribs, and the optimal incision location was determined. The fracture was exposed through as many small incisions as possible, and fixed with titanium plate or clon-type plate. During the operation, the autonomic respiratory anesthesia and paraviral nerve block technology was adopted. In the conservative group (group 2), routine treatment measures such as analgesia, hemostasis and chest band fixation were adopted. The effects of the two treatments on lung function, pain index, complications and QoL were evaluated. It provides theoretical basis for the treatment of rib fracture
