Freedom Adjustable Elbow/Knee Splints are multipurpose soft splints that help restrict elbow and knee movement, or can be used to help prevent joint contractures. The splints are filled with polyester beads for a soft way to position a limb. The A812 series features a zipper opening to allow you to adjust the amount of beads in the splint and is grayish in color. The 550054 series features a nylon loop at the end of the splint that may be pinned or clipped to the patients sleeve to prevent the splint from migrating. The extra small sizes (Item #'s 081292960, 081040625, 081040633 & 081040641) feature a cartoon character print which may be more suited for the pediatric population.
