The posterior antebrachial cutaneous nerve branches from the radial nerve proximal to the elbow and supplies sensation to the posterior aspect of the forearm. With a high‐frequency linear transducer, the posterior antebrachial cutaneous nerve was identified in 8 healthy volunteers. Under aseptic conditions and with an ultrasound‐guided in‐plane technique, 1% lidocaine was injected circumferentially around the nerve. In each participant, the block was successful, and neither incidental blocks of other nerves nor any other complications were observed. These results demonstrate that the posterior antebrachial cutaneous nerve can be blocked to provide anesthesia or analgesia to the posterior forearm.
