2. Mechanism
Plaster is a shell, frequently made
from plaster or fiberglass, that encases a limb (or, in some
cases, large portions of the body) to stabilize and hold
anatomical structures—most often a broken bone (or
bones), in place until healing is confirmed. It is similar in
function to splint
3. Uses
To support fractured bones, controlling movements of
fragments and resting the damaged tissue
To stabilize and test joints in ligamentous injury
To support and immobilize joints and limbs post
cooperatively until healing is occurred
To correct a deformity
To ensure rest of infected tissue
4. Advantage
Versatile, readily applied and fashioned
Reasonably comfortable
Absorbs secretions to some extent
Fairly strong
Radio translucent
Cheap and easily available
5. Disadvantage
Plaster cast require more care than the other type of
cast.
They can't get wet as this cause the plaster to crack or
disintegrate
To bathe with plaster cast you'll need to wrap it in
several layers of plastic
They also take several days to fully harden
Plaster cast tend to be heavier
6. Precautions
Keep the plastered body part raised to prevent
swelling, especially for the first 48 hours.
On average, plaster casts stay on for about six weeks,
depending on your age, general health and type of
fracture.
Even once the plaster is removed, the bone is still
healing so you should take care for at least another
month.
