Bumper fracture:: (A) Fracture of fibula, (B) Fracture of distal tibia, (C) Fracture of medial tibial plateau, (D) Fracture of lateral tibial plateau
Answer is D. Ans. (d) Fracture of lateral tibial plateauRef: BRS: gross anatomy 7th ed. / 83* Bumper fracture is a fracture of the lateral tibial plateau caused by a forced valgus applied to the knee usually by the impact bumper of a moving car on the lateral side of the knee while the foot is planted on the ground.* This causes the lateral part of the distal femur and the lateral tibial plateau to come into contact, compressing the tibial plateau and causing the tibia to fracture.
