Which cast is commonly used for a distal femur fracture with callus formation?

Pantalon Cast Cast Brace Frog Cast Night Splint

Correct Answer:

Cast Brace

Explanation:

Fracture healing requires stabilizing the broken ends while allowing the healing tissue to mature. When callus forms, it indicates that the fracture has gained stability, so immobilization can be transitioned from a rigid cast to a cast brace. The cast brace keeps the knee and distal femur aligned but allows controlled movement, which helps prevent knee stiffness and makes care and hygiene easier. It also supports gradual progression of weight bearing as healing continues. Other options aren’t standard for this scenario because they don’t provide the same balance of stability and controlled motion needed after callus formation, and a night splint is intended for other regions (like the foot) rather than the knee and femur.
