Abstract: An extremity support system comprising a board having an upper surface that supports a resilient member. The board has a curved portion that facilitates it to pivot when connected to a table or bed. It also has a plurality of openings for holding a plurality of straps that can be positioned over the resilient member. The resilient member also includes a rounded end for facilitating the board to pivot; and a top furrow that supports and provides access to an extremity extending off the surface of the table or bed of a patient laying in a plurality of positions. In addition, the straps have methods of placement to function as non-occlusive non-obstructive guardrails that maintain the extremity in the furrow of the resilient member, do not interfere with the ability of the board to pivot, and do not touch the extremity under usual circumstances thereby preventing injuries to an arm or a leg.
