What is the term for a splint that completely surrounds the injured limb?

The term for a splint that completely surrounds the injured limb is a circumferential splint. This type of splint is designed to immobilize the entire limb by encasing it, which helps to provide maximum stability and support to the injured area. This technique is particularly useful when dealing with complex fractures or injuries that require firm immobilization to prevent further damage and to alleviate pain during transport or treatment.

Circumferential splints are usually made from materials like plaster or fiberglass, which can mold closely around the affected limb, ensuring that it is held securely in place. This contrasts with other types of splints, such as rigid splints, which typically support only one side of the limb, or soft splints, which offer less rigid support and are often used for less severe injuries. Supportive splints may also not provide full encasement of the limb, focusing instead on providing general support. Thus, the distinction of complete encasement makes circumferential splints particularly effective for critical injuries requiring thorough immobilization.
