In clinical work, people have some problems, it seems that when they go to a western hospital, patients with fractures are fixed in a cast, while when they go to a Chinese hospital or a combined Chinese and Western medicine hospital, the fracture doctor often uses a splint to fix the fracture. These two methods have been in parallel for hundreds of years. Splinting is a technique handed down from the ancestors of Chinese medicine and is a very effective method, while plaster fixation was introduced from the West and is used more in Western general hospitals. The principle of splinting is to maintain the fracture repositioning and fixation through the compression of the splint. In Western medicine, a cast is used to fix the fracture, often through inter-articular fixation, which means that the cast has to be longer. The fixation of the fracture is done by fixing the distal and proximal joints of the fracture, thus fixing the displacement of the fracture, so the two fixation concepts are different. The splint is used to maintain the fracture by direct repositioning through pressure, while the cast is used to fix the fracture by fixing the joint.
