A 12-5 MHz transverse ultrasound image just above the bifurcation of the sciatic nerve at the popliteal fossa. (a) The sciatic nerve (arrows) is just above and lateral to the popliteal vessels. (b) A sono-guided in-plane lateral side approach to the sciatic nerve with the RF needle (arrowheads). A sensory test with 50 Hz stimulation confirmed a satisfactory needle position, evoking paresthesia in the identical area as the preexisting foot pain. BFM: Biceps femoris muscle; PA: Popliteal artery; PV: Popliteal vein; SN: Sciatic nerve

The sciatic nerve was identified under ultrasonographic guidance just above the bifurcation of the nerve at the popliteal fossa [Figure 1a] and the final location of the needle tip was close to the sciatic nerve in the popliteal fossa [Figure 1b].
