There is a risk of injury to the palmar cutaneous branch of the median nerve (PCBMN) during a volar approach to the carpus or the distal radius. Anatomic variations of the PCBMN increase this risk. We report an anatomic variant of the PCBMN that coursed superficial and radial to the flexor carpi radialis (FCR), reinforcing the need for meticulous subcutaneous dissection to protect the nerve during a volar approach to the distal radius. In this case, identification of the PCBMN variant warranted a modified surgical approach, ulnar to the FCR instead of radial in order to avoid iatrogenic injury. Level of Evidence: Level V (Therapeutic).
