Cast and Splint Care Tips
When you first get your cast or splint
Your doctor has applied a cast or splint to protect a broken bone or injury. If you have a removable splint, follow your doctor's instructions and only remove the splint if he or she says you can. If you have a cast, follow your doctor's instructions for when you can first put pressure on the cast. Fiberglass casts dry quickly, but plaster casts may take several days before they are hard enough to use. Once your cast can be used, don't put excessive weight on it for long periods of time without rest.
A brace with a built-in air cushion is ready to use right away. It is made of either hard or soft plastic and inflatable air pads. The plastic is fitted around the injured area and often held in place with straps. Then the air pads are inflated to firmly hold the injury in place.
Never cut or modify your cast or splint or use powder on the skin under the cast. Keep dirt and sand from getting into the cast.
Your cast or splint may feel tight for a few days after your surgery or injury. This is usually because of swelling. To reduce the swelling by raising the injured arm or leg above your heart as often as possible during the first 72 hours after you get your cast or splint. You may need to lie down, and it helps to use a pillow to prop up the arm or leg and to cushion it from hard surfaces.
Put ice in a plastic bag, wrap it in a towel, and place it over the injured area. If you have a plaster cast, do not get the cast wet or damp. Ice the area several times a day for about 15 minutes at a time.
Taking nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation. Wiggle your uninjured fingers or toes as much as possible. Be sure to follow the medicine precautions on the bottle or box.
Call your doctor immediately if:
It's also important to keep up your muscle strength and tone as much as possible while protecting your injured limb or joint. Your doctor may want you to tense and relax the muscles protected by the cast or splint. Check with your doctor or physical therapist for instructions.
Keeping a cast or splint dry
Itchy skin is common under a cast. Blowing cool air from a hair dryer or fan into the cast may help. Never stick anything inside your cast to scratch the skin.
Don't use oils or lotions near your cast. If the skin becomes red or irritated around the edge of the cast, you may pad the edges with a soft material or use tape to cover it. Call your doctor if you think you have a skin infection.
Complications of wearing a cast
Severe or increasing pain may be a symptom of a serious problem. Compartment syndrome is caused by swelling within the space or "compartment" that contains muscles, nerves, blood vessels, and bones. Pressure on arteries, veins, and nerves causes severe pain, slows circulation to the muscles and nerves, and may cause permanent damage to these tissues. Compartment syndrome is a medical emergency that requires prompt treatment.
Pressure sores are another problem that may develop over a bony area under the cast or splint, such as an elbow or ankle. You may get a pressure sore if your cast or splint is too tight. A warm spot on the cast or splint, pain, drainage, or an odor are symptoms that a pressure sore or skin infection may be present. Call your doctor if you think you have a pressure sore or skin infection under your cast or splint.
