Bone brace is a medical device used to support and stabilize broken bones. It is also known as a SPLINT, which is a 6-letter word that can be found in crosswords. A bone brace is typically made of metal, plastic, or fiberglass and is used to immobilize the affected area. It is often used in combination with a cast to provide additional support and stability. Bone braces are commonly used to treat fractures, sprains, and other injuries.
