A POP bandage is a gauze bandage coated with plaster of Paris. The bandage comes wrapped around a plastic spool, which is designed to allow rapid and even wetting upon immersion. Once wet, the bandage sets, forming a hard and rigid structure that is both porous and absorbent1. It is used as a cast material for immobilization of fractures, diseased bones and joints, correction of deformities and acute splinting
