Aerial supply to the head and neck of femur is: (A) Lateral circumflex femoral aery, (B) Medial circumflex femoral aery, (C) Profunda femoris aery, (D) External femoral aery
Answer is B. The medial circumflex femoral aery (internal circumflex aery, medial femoral circumflex aery) is an aery in the upper thigh that helps supply blood to the neck of the femur. Damage to the aery following a femoral neck fracture may lead to avascular necrosis (ischemic) of the femoral neck/head . Ref - BDC 6th edi vol 2 ; pg 13-15
