Movement of sciatic nerve with dorsiflexion and plantar flexion of foot: A new identification method by ultrasound

Ultrasound guided sciatic nerve block is being performed more than a decade [1]. However, localization of sciatic nerve using ultrasound may be a difficult procedure at midthigh region. The sonogram should be optimized by adjusting the focus, depth, frequency and gain. Essential probe manoeuvres should be applied like pressure, alignment, tilting or rotation. In a previous study, it was noted that 37.5% of patients had a poor or average image quality and required nerve stimulation to confirm ultrasonographic appearance of the sciatic nerve at the midthigh level [2].
