Definition & Meaning of "plaster cast"

What is a "plaster cast"?

A plaster cast is a hard, protective shell that is used to support and protect a broken or injured arm, leg, or other body part while it heals. Applied by medical professionals, the plaster cast wraps around the affected area, keeping the bones in place and preventing movement. Plaster casts are crucial for helping bones mend properly and can be customized in size and shape to fit different parts of the body. They typically stay on until the healing process is complete, after which they are removed by a healthcare provider.
