Casting is used to control the musculoskeletal system pathologies caused by trauma and inflammation, to immobilize and protect the extremity. Plaster of Paris cast is a useful circumferential stabilization method for lower extremity. Generally long leg cast and short leg cast is applied in lower extremity injury but also in some specific conditions patellar tendon bearing cast, total contact cast and hip spica cast can also be used. Complications and risks must be explained to patients before casting, and patients consent must be taken. If cast is not applied properly, pressure ulcers, compartment syndrome, cast syndrome may occur. Because of these complications every orthopedist should know how to apply casting with a proper technique. A doctor can not be an orthopedist without a plaster spotted uniform. Casting is an art for each orthopedist.
