leg cylinder cast

leg cylinder cast

Etymology: ONor, leggr + Gk, kylindros + ONorse, kasta
an orthopedic device of plaster of paris or fiberglass used to immobilize the leg in treating fractures from the ankle to the middle femur. It is used especially for repairing knee fractures and dislocations, for treating soft tissue trauma around the knee, for maintaining postoperative positioning and immobilization of the knee, and for correcting or maintaining correction of knee deformities. The cast extends from the upper thigh to the ankle. The foot is not encased. The long-leg cast may also be used for these purposes because it encases the foot and ensures greater immobilization.
