A hip spica cast is a cast that covers the body. It starts at the chest, goes around the waist and hips, and continues down the legs. It has an opening cut out for diapering or toilet use.
A hip spica cast may be applied after different types of hip or leg surgeries, tendon releases or a broken bone. It serves a very specific purpose: to immobilize the hips and legs, and to maintain the corrected position for healing.
