In the clinical work, the people will have some problems, as if in the western hospital, the patient’s fracture is immobilized with plaster, while in the Chinese medicine hospital or the combined Chinese and western medicine hospital, the fracture doctor will often use the splint to immobilize the fracture. These two methods have been in parallel for hundreds of years. Splinting is a technique handed down from the old Chinese ancestors and is also a very effective method, while plaster fixation is imported from the West and is more commonly used in Western general hospitals. The principle of splinting is to maintain the fracture in place and immobilize it through the pressure of the splint. In Western medicine, fractures are immobilized with a cast, often by cross-joint immobilization, which means that the cast has to be a little longer. It immobilizes the joints near and far from the fracture, thus immobilizing the displacement of the fracture, so the two immobilization concepts are different. Splinting maintains the fracture by direct resetting through pressure, whereas casting immobilizes the fracture by immobilizing the joint.
