Sports Pump on Instagram: "A cast saw used to remove orthopedic casts works differently from a circular saw. It uses an oscillating blade that moves back and forth very rapidly over a tiny angle. This motion easily breaks up rigid plaster or fiberglass cast material, which cannot flex, but human skin flexes with the blade’s motion and doesn’t get cut under normal use. This design allows safe and effective cast removal by trained professionals. Follow @sportpump for more! #medicalcast #medical #h
