An open-framed leg support for patients undergoing a colonoscopy that reduces intrusion into a physicians working space. The leg support has a sturdy base that rests on an examination table (10) and (11). It also has a support surface (23a) and (23b) upon which a patients leg rests, and which is mechanically biased to prevent the leg from falling off of the support. Finally, it has a frame (14) and (15) that joins the base and the support surface on only one side, leaving the other sides open and free of encumbrances. Additionally, it has a crossbar (16) in the frame for stability, and a strut (20) connecting the crossbar to the leg support surface for additional support.
