Arthroscopic Management of Dorsal and Volar Wrist Ganglion.

Dorsal and volar wrist ganglions are benign tumors; most of them are asymptomatic. They can disappear spontaneously. Arthroscopic resection can be performed for pain or cosmetic concern. Dorsal ganglion is more common (70%). The hypothesis of the origin is the result of mucoid dysplasia in association with intracapsular and extrasynovial ganglia that occur at the level of the dorsal scapholunate complex. Volar wrist ganglia are less common (20%) and occur mainly in the radiocarpal joint. They are due to capsular destruction at the volar insertion of the SL ligament and arise from the interval between radio scaphocapitate and long radiolunate ligament.
