Volar Ganglion Cyst and Echo-Guided Assistance for the Arthroscopic Removal.

The ganglion of the wrist is very common but with uncertain prognosis. The arthroscopic resection seems to improve the result compared with open procedure, in decreasing recurrence and morbidity. Volar ganglions are close to the radial artery, the flexor pollicis longus tendon, and even the median nerve. Ultrasonography combined with arthroscopy offers incomparable safety for the resection of volar ganglions. The technical steps of this combined procedure are described, and the first published series are discussed.
