Arm in plaster — and after it comes off

The plaster stays on for as long as we have written on your prescription. The later stages count from the day it comes off.
If your doctor wrote a different plan on your prescription, follow that instead of this page.

Looking after the plaster
- A plaster takes up to 2 days to harden fully. Until then, rest it on a pillow and do not press, knock or walk on it.
- Keep it dry. For a bath, cover it with two plastic bags taped at the top, and still keep it out of the water.
- Never push anything inside to scratch, and do not pull out the padding or trim the edges.
- No oil, powder or cream under the plaster. For itching, blow cool air inside with a fan or a hair dryer on the cold setting.
- Do not cut or remove the plaster yourself. We remove it in the clinic.
When the plaster comes off
- The skin will be dry and flaky. Wash it gently with soap and lukewarm water, pat it dry and put on a plain moisturiser. Do not scrub or pick at it.
- The limb will feel stiff, weak and thinner for a few weeks. This is normal and improves with the exercises.
- Some swelling, aching and stiffness, worse by evening or in cold weather, can last for some months.
Stop and telephone us if
- Pain that keeps getting worse despite the painkillers, or is much worse when you straighten the fingers
- The fingers become numb, tingling, cold, pale or blue
- You cannot move the fingers
- The fingers stay very swollen even with the hand raised
- The plaster feels too tight, or rubs or burns in one spot
- The plaster is cracked, soft, wet or loose, or something has fallen inside it
- A bad smell or discharge from under the plaster, or fever
