Fracture traction has the following two main effects: 1, for conservative treatment of patients, through the fracture traction can avoid displacement of the fracture end, which can promote the healing of the fracture end, and through the traction can reduce the fracture end of the surrounding soft tissue stimulation, the surrounding soft tissue inflammatory edema can be well controlled, and can effectively avoid the fracture end friction pain; 2, for surgical patients, through the bone traction fracture end can be better reset, and after 5-7 days time edema elimination, the surgery can avoid excessive stretching of the fracture end. For surgical patients, the fracture can be reset well through bone traction, and after the oedema is eliminated in 5-7 days, the surgery can avoid excessive stretching of the fracture to reset, and it can reduce the operation time of the surgery, which is a kind of good protection for the patients to avoid anesthesia accidents and other complications.
