What device is used to immobilize injured extremities?

The device used to immobilize injured extremities is a splint. A splint serves the specific purpose of stabilizing and supporting injured limbs, helping to prevent any further movement that could lead to additional injury. It is commonly used in cases of fractures, sprains, or other trauma to the extremities.

Splints can be made of various materials, such as rigid boards, padded supports, or even improvised items, and they are designed to hold the injured area in a fixed position. By ensuring that the broken or injured part remains immobilized, a splint facilitates proper healing and can also minimize pain for the patient.

While a sling is used primarily for supporting an arm, stabilizers and braces have broader or different functions and may not be specialized for immobilizing an extremity in the same way a splint is. The focused design and intended use of splints make them the most appropriate choice for this purpose.
