Which cast is used specifically for a fracture of the distal third of the femur with callus formation?

• A. Basket Cast
• B. Cast Brace
• C. Single Hip Spica Cast
• D. Pantalon Cast

Answer: (B)

When a fracture shows callus formation, stability at the fracture site is improving, so the goal shifts from rigid, bulky immobilization toward a lighter, adjustable support that still protects the healing bone. A cast brace fits this need for a distal third femur fracture with callus because it provides continued stabilization without the bulk of a full hip immobilization. It can be fitted and adjusted as swelling subsides and healing progresses, making it easier to manage and more comfortable while still preventing loss of alignment. Other cast types are typically used for different fracture patterns or stages of treatment and tend to be bulkier or more restrictive; a hip spica is mainly used for larger, pediatric immobilization of the hip and knee, while the basket or pantaloon casts are suited to different configurations or early immobilization needs.
