Endoscopic Ganglionectomy of Palmar Ganglion via Flexor Carpi Radialis Tendoscopy

Palmar ganglion is rare. Deep palmar ganglion usually arises from the wrist joint and may cause compression neuropathy. Superficial palmar ganglion may arise from the flexor tendons of the wrist. The chance of compression neuropathy is expected to be less than deep palmar ganglion. However, there is a higher chance of perforation through the skin and the ganglion may affect hand grip. Open resection of the ganglion does not require extensive deep soft tissue dissection. However, the skin incision can still be extensile to trace the stalk to the tendon of origin. The purpose of this Technical Note is to report the details of endoscopic ganglionectomy for superficial palmar ganglion arising from the flexor carpi radialis tendon
