Multiple Choice

In a motorcycle crash, bilateral femur fractures are most commonly associated with which crash type?

In frontal, head-on motorcycle crashes, the rider experiences a direct, high-energy forward force. That energy often drives the body toward the bike or ground in a way that loads both legs at the same time. The knees and thighs can be driven into the frame, pegs, or dashboard with substantial axial compression and bending, so the femurs on both sides are subjected to similar stresses simultaneously. That symmetrical, high-energy loading makes bilateral femur fractures more likely in head-on crashes. Other crash patterns tend to produce injuries that are more unilateral or involve different structures, so they don’t explain the same bilateral femur fracture pattern as effectively.
