Forearm cast

Forearm cast

Doctor's advice

Your doctor’s advice

A doctor has assessed you and decided you need to go into a forearm cast.

This type of cast goes from below the elbow to below the knuckles, immobilising your wrist.

It is important that you follow the instructions given.

✓ Do

Keep your cast clean and dry

Getting it wet could irritate your skin. Either wrap a towel around it and keep away from water or purchase a waterproof cover (these are available online).

Do some exercises

Making a fist and stretching fingers out will also help relieve swelling. It is very important to keep the joints not in cast moving. If struggling to make a fist, opposite hand can be used to help fingers flex and extend.

Keep the casted arm elevated

In order to alleviate swelling/symptoms of swelling, arm must be elevated with hand above ear whilst making a full fist and releasing fingers for up to five minutes each hour. You should elevate arm whilst sat or stood up, not when laying down.

Get help if you need it

Contact plaster room if your cast becomes broken.

Be vigilant of cast rubbing/burning sensation inside cast. Contact plaster room ASAP.

If you have pain that cannot be controlled with pain relief you must attend A&E immediately.

Don't ✘

Don't remove your cast

Never attempt to remove a cast yourself unless you have been given specific instructions to do so.

Don't put plastic bags around the cast

Do not put plastic bags around the cast, these are not waterproof and can cause skin issues under the cast.

Don't stick objects in your cast if itching

This can cause additional skin problems under the cast that may require further medical treatment.

Never attempt to trim your cast

If there are rough edges or your skin is irritated around the ends, contact plaster room.
