The cast should be moulded, depending on the type of cast, to maximize its fit on the limb.

Because the wrist is shaped like a box, the cast in this area should be moulded to take on a similar shape. Rub the cast to help the plaster layers adhere to each other and give it a smooth surface.

Three point moulding should also be used to improve immobilization at the fracture site. To mould, apply pressure with the flat palmar surface of your hands.
