The SAM (Structural Aluminum Malleable) Splint contains all the properties of the many other splints that it replaces. It is constructed of .02 strips of soft aluminum with a polyvinyl coating. This metal presents no impediment to X-rays. When folded into a "structural bend" longitudinally the splint becomes quite rigid and easily supports the leg, forearm or humerus. It can also be contoured and crimped to stabilize the cervical spine. The coating on the SAM Splint does not stain and the splint is reusable with proper cleaning. This SAM Splint is 4-1/4" x 36" and is shipped flat. Please specify Orange or Gray Splint when ordering. Additional features include: Can be applied to a variety of fracture locations Easily trimmed (to form finger splints) Easily stored (flat or rolled) Inexpensive Easily carried
