The methods of fixing splints for fractures are as follows: 1. Use flexible willow boards, bamboo boards or plastic boards to make small splints of suitable length and width, add fixation pads to the fracture site, tie the splint outside the fracture site, and tie the horizontal band outside to fix the fracture site. 2. In the process of fixing the small splint, avoid tying it too loosely or applying the fixation pads improperly, which can easily lead to re-displacement of the fracture. Tying the splint too tightly can produce serious consequences such as pressure ulcers, ischemic muscle contracture, and even limb necrosis, especially tying too tightly can cause ischemic muscle contracture, which is the most serious complication of fracture and can easily lead to serious disability and should be prevented, and the small splint can effectively prevent fracture angulation, rotation and lateral displacement.
