Fig. 3From: Comparison of sciatic nerve block quality achieved using the anterior and posterior approaches: a randomised trialUltrasound image of the sciatic nerve obtained with the anterior approach during the block is shown in the short axis (transverse view). ALM: adductor longus muscle, AMM: adductor magnus muscle, GMM: gluteus maximus muscle, LT: femur (lesser trochanter), VLM: vastus lateralis muscle, LA: local anesthetic, Arrows: Sciatic nerve; triangles = needle.Back to article page
