Splints and casts are like big bandages that are used to treat injured bones.
They are wrapped or fitted to an injured area.
They hold the injured area in place so that it heals correctly and cannot
move.
Why does my child need one?
Casts and splints hold an injured bone in place so that it can heal correctly.
They support and protect injured bones.
They help reduce pain and swelling.
Your doctor will decide whether a cast or splint is best for the injury.
What are the risks? After a cast or splint is put on, watch for signs that there may be a problem.
Sometimes, the cast does not fit right. If you notice any of the following symptoms,
call your doctor immediately:
Increased pain
Feeling that the cast or splint is too tight
Numbness or tingling in the hand or foot of the injured area
Burning and stinging
Much swelling below the cast, in the fingers or toes
Loss of movement in fingers or toes
Fingers or toes are cool
Fingers or toes turn bluish or gray
Skin under the cast is a strange color or odor
How is it put on? Splints and casts are put on by a doctor or other trained assistant. Your
child may need X-rays first.
Splints
Splints can be made new to fit your child, but often they are already
made and then adjusted.
For example, some can be adjusted using Velcro straps.
Since they can be adjusted, splints are helpful if the injured area
is swollen. The splint can be made larger or smaller so that it fits the
injured area correctly.
They come in many shapes and sizes.
Sometimes, a strap is attached to the splint and goes around the neck
to help hold the arm.
They are easier and faster to use than casts.
They are easier to take on and off.
The splint can be easily taken off so the injured area can be exercised
as it continues to heal.
Casts
First, a soft layer of padding is put against the skin of the injured
area.
Next, strips of fiberglass or plaster are dipped in water. They are
put over the padding. When it dries, the cast turns hard.
The cast holds the injured bone in place so that it can heal correctly.
After swelling to the injured area goes down, the cast might be too
big. A new cast may be needed.
Casts can also become too tight if swelling increases.
After awhile, the doctor might decide to begin using a splint. The splint
can be easily taken off so the injured area can be exercised as it continues
to heal.
How is it taken off?
Your child will probably have to wear the splint or cast from a few weeks
to a few months.
A doctor or trained assistant should take off the cast. Never do it at home.
The doctor uses a round saw to remove a cast. The saw makes a loud noise.
It shakes, but does not turn. It does not cut the skin.
The padding will protect your child's skin.
Is it painful?
Removing the cast is not painful. The saw makes a noise that sometimes scares
children but it does not hurt. It may make the area warm.
What care will my child need?
After a splint or cast is put on, elevate the injured area for 24 to 72
hours.
Raise it above the heart. Prop it up on a pillow or something else. If your
leg is injured, you should sit reclined (leaning back) or lay down.
Move the fingers and toes of your uninjured arms and legs gently, and often.
Put ice on the cast or splint. Put the ice in a plastic bag and wrap it
loosely around the injured area.
How do we care for it?
Some casts and splints are waterproof. Ask your doctor how wet it can get.
Other casts and splints should be kept dry.
Cover it with two layers of plastic to keep it dry while your child bathes.
Children should not play on wet grass or sand.
Cover the cast in wet weather.
Do not cover a new cast that is still drying.
Do not walk on a "walking cast" until it is dry. It takes about one hour
for a fiberglass cast to become hard and about 2 to 3 days for a plaster cast
to become hard.
Keep the cast or splint clean. Do not let dirt, sand, or powder get inside
it.
Do not stick anything inside it, such as coat hangers, to scratch the skin.
If it is itchy, use a blow-dryer set on "cool" and let the air blow inside
the cast.
Do not put powders or lotions near the skin of the cast or inside to ease
itching.
Do not break off, trim, or sand rough edges of the cast. Cover the rough
edges with tape and call the doctor.
It's okay to use markers to sign the splint or cast.
When should I call the doctor?
Call the doctor if the skin under the cast is itching and it can't be relieved.
Call the doctor if your child has any of the symptoms listed under "Risks"
above.
Call your doctor if the cast has rough edges, is cracked, or has soft spots.
Cover rough edges with tape until you can see a doctor.
Call the doctor if the skin around the cast becomes red or raw.
Call the doctor if you have questions about how to care for the cast or
splint or how to keep it dry.
Call the doctor if you have questions or concerns about your child's condition.
