Which cast is indicated for pelvic affection?

• A. Basket Cast
• B. Frog Cast
• C. Night Splint
• D. Pantalon Cast

Answer: (D)

When a pelvic injury needs solid immobilization, you want a design that holds the pelvis and both hips in place so there’s no movement at the pelvic ring during healing. A pantaloon cast, a hip spica style cast, does exactly that by extending from the trunk down over the legs, effectively immobilizing the pelvis and hips. This prevents motion at the sacroiliac joints and acetabulum, helping stabilize fractures or severe injuries in the pelvic area and reducing pain as healing occurs.

Other casts and devices don’t provide this level of pelvic immobilization: a basket cast targets the forearm or hand, a night splint is used for foot/ankle problems, and a frog cast is used for specific hip positioning but does not stabilize the pelvis like a hip spica does.
