Cast care instructions

Here are some tips and directions on how to properly care for a cast on your arm or leg.

Cast care instructions

Cast care is particularly important in the first few days. You want your recovery process to get off on the right foot, so understanding the best practices for maintaining your cast during this time will help solidify your recovery and help your injury begin to heal as it should.

Clean and dry your cast

It is very important to keep your cast dry when bathing or showering. Although fiberglass is resistant to water damage, your cast should not get wet. The cotton lining under the fiberglass or plaster can become wet, and may cause skin breakdown or irritation. If the cotton lining gets wet, try to dry it with a blow dryer on a low, cool setting. If you are unable to dry it, or the skin becomes itchy, you should advise our office of this condition as soon as possible.

If you have a cast on your leg and it is wet outside, put a bag over the cast to keep it dry. If it is a walking leg cast, put your cast shoe on over the cast and the bag. Do not put the bag on the outside of the cast and cast shoe, as the bag can be slippery and cause further injury.

Waterproof casts

Waterproof casts are not used for several different types of fractures. They are also not appropriate for certain body parts. However, if you have been given a waterproof cast, then you are able to get this cast wet.

It is still very important to make sure that all of the water drains out of the cast after getting wet each time. This can be accomplished by simply holding the cast vertically to allow the water to drain out adequately. Another recommendation is to rinse each cast out with clean tap water after any exposure to chlorinated water (swimming pools, hot tubs, etc.).[No text in field]

Do not insert anything into your cast

You should never scratch yourself by inserting anything into the cast. If you do so, you risk cutting your skin beneath the cast, which could result in an infection. Also, if an item does become lodged in, or falls inside of, the cast, please notify us immediately. This can cause skin irritation and skin breakdown.

Elevate your cast

Swelling around the area of a broken bone can increase anywhere from one to three days following an initial injury. If and when you encounter swelling, it will make the cast feel tighter, potentially making your pain worse. One way to alleviate this is through elevating your cast above your heart level. This generally requires you to be lying down.

When trying to decide how high to elevate your cast, ask yourself if water would run "downhill" from the fractured bone to the heart. If so, that is a good elevation. Elevation should continue until the swelling and tightness go away.

When elevating a leg cast, pillows should be placed under the leg and calf, as this leaves the heel free and can prevent sores from developing.

Gently exercising or stretching the fingers or toes of the limb with the cast on can also help to reduce swelling.
