The main methods of forearm fracture fixation are plaster fixation and splint fixation. Plaster fixation is usually required to fix the 2 joints adjacent to the fracture, and the effect of fixation is more definite. It is also easier to take care of the fracture, just pay attention to the tightness of the cast. If the cast is too loose, the fracture will be easily displaced because of the loss of fixation. If it is too tight, the blood circulation will be affected and muscle and nerve damage will easily occur. Splinting is inconvenient mainly in the usual care, because splinting often loosens the splinting area and requires re-fixing. It is not possible to do this at home or sometimes the fracture may be displaced due to poor technique. In addition, the splinting needs to be reviewed at the hospital in 3-5 days to review the tightness of the splint and the X-ray to check the location of the fracture, which is troublesome.
