In fracture of femur by which pa popliteal aery is commonly damaged by-: (A) Proximal fragment, (B) Distal fragment, (C) Muscle haematoma, (D) Tissue swelling
Answer is B. *In distal third shaft fracture or supracondylar femur fracture, the distal fragment is tilted backward due to strong gastrocnemius pull. This posteriorly tilted distal fragment can cause popliteal aery injury. Ref: Apley's 9th/e p. 865
