44 Anterior Sciatic Nerve Block The anterior approach to proximal sciatic nerve block can be used in patients who are difficult to position lateral or prone. This supine approach is deeper than other approaches because the sciatic nerve lies far from the anterior surface of the thigh and is therefore primarily used in thin patients. Suggested Technique First obtain a long-axis view of the femur with the transducer placed on the anterior aspect of the thigh. The femur is easily identified by its bright cortical surface and acoustic shadowing. Next, slide the transducer medially to obtain a long-axis view of the sciatic nerve at approximately twice the depth of the femur. The sciatic nerve is wide and straight and therefore appears as an echogenic linear structure lying deep to the adductor magnus muscle. If the femoral artery is visible, then the transducer has slid too far medially. Only gold members can continue reading.
