Which cast is a cylinder mold used for fracture of the patellar with open wound, swelling and infection?

• A. Delvit Cast
• B. Quadrilateral/Ischial Weight Bearing Cast
• C. Short Leg Posterior Mold
• D. Cylinder Mold

Answer: (D)

When a patellar fracture occurs with an open wound, swelling, and possible infection, the immobilization choice must stabilize the knee while not squeezing swollen tissue or hindering wound care. A cylinder mold cast fits this need because it creates a cylindrical sleeve around the leg that supports the knee and stabilizes the fracture without applying tight circumferential pressure across the wound. This design accommodates edema, reduces the risk of skin problems, and allows ready access to the wound for drainage and inspection. The knee area remains relatively immobilized, but the cast avoids the constriction of a full leg cast, which is important while swelling and infection are present. Other cast types listed are less appropriate because they either target different injuries or impose more rigid, compressive immobilization around the swollen knee, which isn’t ideal in the presence of an open wound and infection.
