Nerve Block Tip of the Week: Adductor Canal Block

October 26, 2022

An adductor canal block anesthetizes the skin from the medial aspect of the leg and knee to the ankle joint and foot. The technique consists of injecting 10 mL of a long-acting local anesthetic (e.g., bupivacaine 0.25% or ropivacaine 0.5%) next to the femoral artery and around the saphenous nerve in the adductor canal. 

As part of our “Nerve Blocks from the App” series, we’re sharing 3 steps to help you identify the correct plane for injection.

  1. Identify the femoral artery deep in the sartorius muscle.
  2. Identify the limits of the femoral triangle and adductor canal by scanning up and down until the medial border of the sartorius muscle meets the medial border of the adductor longus muscle.
  3. From this point, continue to scan distally until the adductor longus muscle becomes shorter and the artery is located in the middle of the sartorius muscle. This location is an adequate site for injection.
