Abstract:
Dorsal wrist ganglia are the most common mass of the upper extremity. Treatment modalities include benign neglect, aspiration, and surgical excision. Arthroscopic excision is a less invasive surgical alternative to open resection with the benefit of visualizing and treating other intra-articular pathology, fewer potential complications, earlier return to activities, and possibly, a more complete resection. This may lead to a lower rate of recurrence, although this has not been proven in the literature. Recurrence depends in part on adequate ganglion stalk visualization and resection. This is often difficult in open and arthroscopic ganglionectomy. This work describes a new technique with improved arthroscopic stalk visualization and ganglion resection using intralesional injection of an inert dye.
