What artery supplies the head of the femur?
The answer is the medial circumflex femoral artery (not the lateral)
Common case scenarios are those of hip dislocation or avascular necrosis of the head as seen in sicklers.

You can see that the lateral circuflex femoral artery mainly supplies the upper portion of the femoral shaft while the medical circumflex femoral artery supplies most of the portions of the head of the femur, both arteries are branches off the profunda femoral artery.
