Which cast is associated with ankles, tarsals and metatarsals affection?

• A. Long Leg Circular Cast
• B. Cylinder Mold
• C. Short Leg Circular Cast
• D. Short Leg Posterior Mold

Answer: (C)

When an injury involves the ankle and the bones of the foot (tarsals and metatarsals), you want a cast that firmly immobilizes the ankle and foot while keeping the knee free to bend. A short leg circular cast achieves exactly that: it runs from just below the knee down to the toes and is wrapped completely around, providing uniform, rigid support that prevents movement at the ankle and across the foot. That level of immobilization is what's needed to allow healing in these bones.

A long leg cast would unnecessarily immobilize the knee, which isn’t needed for most ankle/foot injuries and can complicate recovery. A short leg posterior mold offers a different, more specific type of support that’s used in particular swelling scenarios and doesn’t provide the same full circumferential immobilization. A cylinder mold isn’t the standard configuration for immobilizing the ankle and foot either.
