Taking Care of Your Cast

Plaster
  • Do not push objects under the plaster. This could lead to a wound in the skin.
  • Do not wet the plaster as it could soften and become unsupportive.  Although any cast would probably dry eventually, it could lead to the skin beneath the cast becoming macerated.
  • Do not let cracks increase in size. This could make the plaster unsupportive.

If there are any problems with the plaster, let us take a look. It could be as simple as reinforcing the plaster or renewing the whole plaster, if necessary. You may call the Fracture Clinic between 7:00 a.m. and 3:00 p.m., Monday to Friday. Or you can contact your Family Physician or return to the Emergency Department if the following problems occur:

  • Cast becomes loose or uncomfortable
  • Cast becomes tight
  • Your fingers or toes become swollen or blue
  • There is a tingling sensation or numb feeling
  • There is a discharge or smell from the cast
  • There are painful areas beneath the cast.
Synthetic

The synthetic cast is a knitted glass fibre fabric impregnated with a polyurethane resin.  A synthetic cast is typically used as a follow-up to a 'Plaster of Paris' splint when the injury has settled.  It is also used when there is minimal swelling.  When wearing this type of case, do not:

  • Cut the cast. This will leave a sharp edge, which could cut into the skin.
  • Heat the cast. This could lead to a burn to the skin.

Exercises

If the cast is on your arm, you must exercise your fingers for five minutes in every hour that you are awake.
  • Make a tight fist, hold for the count of five, then relax
  • Spread your fingers out for the count of five, then relax
  • Your elbow and shoulder must be moved as normal so they don't stiffen up
If the cast if below your knee, move your toes for five minutes every hour while you are awake.
  • Sit with your foot elevated on a pillow if your toes become slightly swollen
  • Do not allow your knee to become stiff
If the cast is above the knee move your toes for five minuts every hour while you are awake.
  • Tighten your knee for the count of five, then relax
  • Lift your leg, hold for the count of five, then relax

*Exercises can be carried out unless told otherwise by medical staff.
