To maintain the effectiveness of traction, we need to pay attention to the following points: 1. First of all, we need to keep the traction area not to be dragged around. For different treatment areas, the required traction area also varies. For example, in the cervical spine traction, need to use the jaw traction belt, the jaw and the posterior occipital ridge at the same time pocket, and then fixed by traction bow. At this time must not make the traction part slip off. 2, pay attention to the direction of traction to keep correct. Generally speaking, the direction of traction should be parallel to the long axis of the part to be tractored. 3, pay attention to the appropriate weight of traction. In the process of traction, the doctor will adjust the weight of traction according to the patient’s own weight and the traction site. In the traction process, the patient must not be able to adjust without permission. 4, need to do continuous traction. Generally the most effective traction is continuous traction. Only through continuous stretching can the tiny joint be reset, muscle spasm be relieved, and the fracture end be continuously stabilized.
