The adductor hiatus is a hiatus (gap) between the adductor magnus muscle and the femur that allows the passage of the femoral vessels from the anterior thigh to the posterior thigh and then the popliteal fossa. It is the termination of the adductor canal and lies about 2 inches superior to the knee.Four structures are associated with the adductor hiatus. However only two structures enter and then leave through the hiatus; namely the femoral artery and femoral vein.
