After sustaining a stable fracture, the first order of business is to protect the injured limb or body part from further damage. In order to do so, your doctor will immobilize the bone with a splint or cast. Since the bone fragments remain in alignment in a stable fracture, there is no need to perform a realignment procedure. The casting process will occur in a few different steps. If a limb has been broken, a soft sock will be applied to minimize itching and protect the limb from edges. Then, a cotton wrap will be applied over the sock to add padding. Finally, two layers of casting material are wrapped over the cotton wrap. The second layer can be a color of your choosing or a generic type.
