Final answer:
A basic type of splint includes rigid, formable, and traction splints.
Step-by-step explanation:
A splint is a device used to immobilize and support a broken or injured bone. There are several types of splints that serve different purposes. One basic type of splint is a rigid splint. This type of splint is made of hard material, such as wood or plastic, and provides firm support to the injured area to prevent movement. Another basic type is a formable splint, which is made of pliable material, such as foam or bandages, and can be molded to the shape of the injured limb for a customized fit. Lastly, a traction splint is used to pull or align fractured bones, reducing pain and promoting healing.
