Doctors cast or put splints on fingers for a variety of orthopedic and rheumatological conditions. The casts and splints can immobilize a fracture, allowing it to heal, and can also be used to secure a limb following a surgical intervention. Plasters are usually constructed from fiberglass or plaster. Fiberglass is lighter and usually more durable, but plaster can be molded more easily than fiberglass and is less expensive.
For the care of a plaster, keep it clean and dry. Avoid washing your fingers if they are in a cast, as it increases the risk of getting wet. Resist the temptation to relieve the itching, by placing talcum powder, deodorant or even a hook of underwear from your cast. Try to prevent dirt from getting into the plaster as well. If something gets into the cast, or if it gets wet, do not remove it on your own. Call your doctor to make the cast.
Regularly inspects the deterioration of both the plaster and the skin. Contact your doctor if you notice cracks or damage to the cast or if there is evidence of skin irritation, especially if your skin looks pale or discolored. Never throw out the filling inside your plaster, as this can cause roughness which, in turn, can lead to skin ulcers or irritation.
Splints are made of plastic, fiberglass or plaster. Unlike casts, the splints do not fit completely around the injured limb. Instead, they support at least one surface of the injured limb. The splints can be prefabricated or made to order. The splints should also be kept dry and clean.
Because the extremities can swell when the splints or casts are placed for the first time both can be repositioned in the finger. The finger will reduce its size as the swelling goes down or due to muscle atrophy, which is a decrease in the size of the muscle due to disuse. If the cast or splint moves, it can create pressure points on the skin and cause tissue damage.
