A method of splinting limbs of a patient by a single person and an elongated splint device, for use in the method. The splint device has a first track member and second and third elongated riding members movably held and positioned on the first track member. The riding members are freely movable on the first track member along a single longitudinal axis to obtain a proper length for splinting and a releasable locking mechanism is included to maintain the selected length. Two or more adjustable belt elements are removably connected to the riding member and serve to affix the splint device to a patient in a proper splinting position.
