Ganglions are the most common soft-tissue tumors seen and treated in the hand and wrist. A wide variety of treatments have been described including observation, aspiration, sclerotherapy, and open surgical excision. Arthroscopic ganglion resection provides a minimally invasive means to safely resect dorsal wrist ganglions while avoiding the requisite scar accompanying open resection. Arthroscopic ganglionectomy allows a more complete examination of the wrist to include the etiology and location of the ganglions, and associated intra-articular problems. Arthroscopic resection is an approach that prevents some of the complications of an open excision, and that may provide a lower recurrence rate.
