A serious complication of fractures of the femoral neck is avascular necrosis of the femoral head. This usually results from rupture of which aery?
Correct Answer: Medial circumflex femoral
Description: It is impoant to remember that the medial circumflex femoral aery supplies blood to the femoral neck. During fractures of the femoral neck, this aery may be ruptured, and the femoral neck will be deprived of blood. The acetabular branch of the obturator aery provides blood to the acetabulum of the hip bone, which aiculates with the head of the femur to form the hip joint. The deep circumflex iliac aery is a branch of the external iliac aery that runs on the deep aspect of the anterior abdominal wall, supplying that region. The descending branch of the lateral circumflex femoral supplies the lateral thigh and hip.
