Casts are typically made of plaster or fiberglass, each of which have pros and cons.
Fiberglass
Most casts used today are fiberglass.
Like plaster casts, fiberglass casts are wrapped over a few layers of cotton that protect the skin.

Keeping the cotton clean and dry is very important for your comfort.
Plaster casts are most often used when repositioning the bone (fracture reduction) is done.
This is because plaster can be molded to the individual patient and support the bone better.
The problem with plaster is that it is heavy and must stay dry.
Water will ruin the cast’s shape and can cause problems with healing.
Plaster casts can also be hard to deal with because they’re bulky and heavy.
What Is a Soft Cast?
A soft cast is otherwise known as a splint or temporary cast.
Once the swelling has gone down, a person can be fitted for a cast.
Summary
Casts for broken bones are commonly made of plaster or fiberglass.
While plaster is supportive, it is bulky and heavy.
Fiberglass is often preferred because it’s lighter and can get wet.
Once the swelling goes down, it’s possible for you to get fitted for a cast.
