The immobilization of a fracture (for example of hands and feet) is done by fixing with splints two joints adjacent to the fracture, above and below the place of the fracture. Under the splint, a soft gauze bandage (or cotton wool) is applied to prevent injury to the soft tissues. In the event that no splints are available, the immobilization can be done with scarves or triangular cloths. The fractured bone is placed on the piece of cloth, as straight as possible, and the corners of the material are tied so that 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, can be too elastic, will not allow the skin to breathe and sweating may occur.
SPLINT, splints, = Piece (of wood, cardboard or metal) used to temporarily immobilize fractured limbs. Therefore, by using rigid cardboard you would make a splint, and the question refers to the situation in which no splints are used.
