This document provides an overview of plaster of Paris (POP) casts, including their history, uses, classifications, application process, aftercare, and potential complications. POP casts are made from calcium sulfate and are used to immobilize and support fractures, joint injuries, and corrected deformities. They are classified based on their application (slab, full circumference cast, or spica cast) and involve applying multiple layers over the injury site. Aftercare includes keeping the cast dry and clean while avoiding heat, with potential complications including joint stiffness, pressure sores, and nerve palsy.

4. Use of cast
To support fracture bone
To stabilize joint and ligament injury
To correct deformity
To support immobilized joint and limb after post op

5. Classification
Based on application
Slap -partial circumfrance
Cast-full circumference
Spica-trunk and limb

6. Steps in application
Examination
Surgeon should examine the fractursite and evalute neuro
vascular status an review x-ray
 Prepare the requred layer 8-12 uppr extemity
12-16 lower extrimity
One joint above and one joint below
Not to lose and not tonight
