Common questions our doctors are asked
If a plaster cast, or the padding underneath a cast, becomes wet, you should see your GP or local hospital within 24 hours. The cast may need to be replaced to protect the skin underneath.
If you go to the ER: You get an immediate x-ray and immediate result. If there is a broken bone, the ER doctor will cast or splint you right away.
If there are sore areas or a foul odor from the cast, cracks or breaks in the cast, or the cast feels too tight or too loose. You develop swelling that causes pain or makes it so you cannot move your fingers or toes. You develop tingling or numbness in the arm or fingers or toes. Your fingers or toes are blue or cold.
It depends on which type of cast you're getting. Fiberglass casts start drying right away and might only take a few hours. Plaster casts usually take a day or two to completely harden. Be careful with your cast while it's still drying.
The skin under the cast can get itchy. Never put anything down into the cast to scratch. For itchiness, use a hair dryer on a cool, low setting and blow air into the cast. You may use diphenhydramine (Benadryl) for itching.
Excessive swelling of your limb below the cast could be a signal that swelling and pressure are impeding your blood circulation.
A plaster cast or splint may take a few days to dry completely, so don't put any weight on it for the first 48 hours. Be careful to keep your cast or splint dry. If it gets wet, it could irritate your skin or lead to an infection. So cover it with at least two layers of plastic when you bathe or shower.
Waterproof casts are made from Gore-Tex and will allow you to get your cast wet when showering or swimming. Waterproof casts tend to produce less sweat and odor and help keep your skin cleaner.
For instance, your cast may need to be replaced if you notice: A foul smell, which may be a sign of an infection. Increased pain or a tight feeling after a few weeks, which may be swelling that isn't going away. Numbness and tingling, which can mean there is too much pressure on your nerves.
Keep the cast dry
So your cast must stay dry. Don't do activities that can get your cast wet. These include swimming, fishing, washing dishes, and even going out in the rain. Bathe as directed by your healthcare provider.
Urgent care facilities, while having access to imaging tests and medical professionals to serve patients with broken bones that require casts or splints, might recommend visiting an emergency room if they feel the broken bone needs emergent attention.
"Unsafe" cast operator
If the cast isn't possible, the compiler throws an exception. This is why it's called unsafe. In the previous example, if y is null , the code above also throws an exception. This is because null can't be cast to String , as String isn't nullable.
If the cast gets wet, use a hair dryer on the cool setting for 5 to 10 minutes. Repeat as needed. If the cast gets too wet and will not dry, call the orthopedic office. Your child may need to have a new one put on.
Itching skin
Do NOT put any objects inside cast to scratch. You may blow air down cast by using a hair dryer, on the cool setting, to relieve itching. Rubbing skin above the cast or placing ice packs over the itchy area may also help. Over-the-counter Benadryl can also relieve itching, but may also cause drowsiness.
It's normal for your cast to get smelly after you've worn it for a while. But if you notice a foul odor or a discharge coming from the cast, it could mean your skin underneath is infected. Get it treated right away.
While fiberglass casts are much more water-resistant than plaster casts, they are not completely waterproof and can become compromised if they get wet. The outer layer of the cast is waterproof, but the soft padding underneath is not. The moisture can cause the fibers to swell and loosen, leading to re-injury.
How and when to dry. Let the waterproof cast dry out completely before getting it wet again. Don't leave it wet at bedtime. Use a blow dryer on cold or very low heat to help dry the cast.
Itching or Burning Sensation Under the Cast
If the skin under your cast feels hot and itchy, it could be a sign of too much moisture trapped underneath, which can lead to skin breakdown and infection.
Protect it with a large plastic bag closed at the top end with a rubber band. Use two layers of plastic to help keep the splint dry. Or you can buy a waterproof shield. If a splint gets wet, dry it with a hair dryer on the “cool” setting.
Numbness or Tingling
This should wear off in a few hours. But if you feel constant numbness or tingling in the fingers or toes of the casted arm or leg, this may indicate that the cast is too tight or that a nerve has been injured.
At night, with less activity, movement of the synovial fluid is limited, which leads to pain and swelling.
