The immobilization of a fracture (for example in hands and feet) is done by fixing with splints the two joints adjacent to the fracture, above and below the fracture site. Under the splint soft gauze bandage (or cotton) is applied for preventing the injury of the soft tissues. In case splints are not available, immobilization can be done with scarves or triangular cloths. The fractured bone is placed on the piece of cloth, in a position as straight as possible, and the corners of the material are tied so it can be suspended. For example, the forearm is placed on the piece of cloth and the tied corners are passed around the neck to support the hand in a horizontal position.
A sheet of plastic material generally does not have good resistance, it can be too elastic, it will not allow the skin to breathe and sweating may occur.
SPLINT, splints, = Piece (made of wood, cardboard or metal) used to immobilize fractured limbs temporarily. Therefore, using rigid cardboard you would make a splint, and the question refers to the situation in which splints are not used.
