palmar cutaneous branch (PCB) studies

The palmar cutaneous branch (PCB) is the sensory branch of the median nerve which supplies the thenar eminence, and it originates at the radial side of the median nerve about 5 cm proximal to the radial styloid. Some authors developed techniques to identify the cause of pain, paresthesia, or similar symptoms in the thenar eminence assessing functional integrity of the PCB, or suggested comparison between PCB and median sensory branch to the digit I to make diagnosis of carpal tunnel syndrome (CTS). Because the PCB transverses the carpal ligament through its own tunnel and it did not pass through the carpal tunnel, it should not be affected in the CTS.
