The sciatic nerve is imaged approximately at the level of the minor trochanter. At this location, a curved transducer placed over the anteromedial aspect of the thigh will reveal the musculature of all three fascial compartments of the thigh: anterior, medial, and posterior (Figures 2 and 3). Beneath the sartorius muscle is the femoral artery, and deep and medial to this vessel is the deep artery of the thigh. Both can be identified with color Doppler US for orientation. The femur is seen as a hyperechoic rim with a corresponding shadow beneath the vastus intermedius.
