Tips for the Popliteal Sciatic Nerve Block

January 24, 2023

The popliteal sciatic nerve block is indicated for foot and ankle surgery, foot and toes amputation, and Achilles tendon surgery. The use of ultrasound improves the success rate and reduces the risk of complications.

Here are our 3 steps to perform a popliteal sciatic nerve block successfully

  1. Place the transducer transversely 3-5 cm above the popliteal fossa between the biceps femoris, and semimembranosus and semitendinosus tendons.
  2. Identify the sciatic nerve where the tibial (TN) and common peroneal (CPN) nerves start separating but are still within Vloka’s sheath.
  3. Insert the needle in-plane or out-of-plane into Vloka’s sheath between the TN and CPN, and inject 10-20 mL of local anesthetic.
