Orthopedic Cast

POP Bandages (Plaster of Paris)  are gauze rolls impregnated with calcium sulfate hemihydrate, used to fabricate custom, rigid external casts. When activated in water, they undergo a chemical reaction that generates heat and hardens into a solid structure, providing excellent immobilization for fractures, severe sprains, and post-operative protection. Valued for their superior moldability and radiolucency, they remain a fundamental tool in orthopedics. Their application requires skilled technique with strict attention to thermal safety, padding, and post-application monitoring for circulatory compromise. Proper dry storage is essential to maintain shelf life.
