Three‐dimensional image of an actual body part reproduced in a castable material.
A positive reproduction of a shape created by pouring a material that hardens into a mold, matrix, or impression of the needed shape.
A negative mold or copy formed in a hollow organ or part (e.g., kidney or bronchi); a urinary cast is a small structure formed within the urinary system from mineral or protein matter and extruded from the body in the urine.
In botany, a type of fossil that results from the filling of a cavity formed by the decay of plant tissues.
Application of a rigid form around a body part or fracture to stabilize it in fixed position to facilitation healing.
A firm splinting device used to enclose and immobilize injured bones and soft tissues in the limbs or torso so that healing can occur. By keeping broken bones and injured soft tissues covered and compressed, a cast maintains a bone in place so that it can heal properly and prevents movement that might cause further injury.
A rigid casing for a limb, nude with open-woven bandage impregnated with plaster of Paris and applied while wet. A plaster cast is designed to protect a broken bone and prevent movement of the aligned bone ends until healing has progressed sufficiently.
Method of manufacturing shears; a metal-forming process whereby molten steel is poured into a mold and, once the metal is cooled, takes on the shape of the mold.
A cast is a formation of bodily tissue or fluid that takes on the form of the cavity where it is found. These casts are categorized based on their point of origin, such as the lungs for bronchial casts, the intestines for intestinal casts, and the kidneys for renal casts. Renal casts are particularly significant and are further classified by their composition—like blood, epithelial, fatty, fibrinous, granular, hyaline, or mucous—to help diagnose kidney diseases. Intestinal casts, which can be found in certain types of colitis, are the next most significant type.
The term can also refer to a mold created from materials like plastic or plaster of Paris.
