Results and complications in dorsal and volar wrist Ganglia arthroscopic resection.

The authors present the procedure and results of five years of arthroscopic treatment of wrist radiocarpal and midcarpal ganglia. Thirty cases of dorsal ganglia and seventeen cases of volar ganglia were operated on arthroscopically. The technique was easy to perform in all the radiocarpal ganglia, not easy in midcarpal dorsal ganglia and very difficult in midcarpal volar ganglia. The results were recorded with a mean follow-up of 15 months. Twenty-seven cases of dorsal ganglia and twelve cases of volar ganglia had excellent results with active motion recovery, no complications, absence of scars and no recurrence. Two cases had a recurrence. There were four complications: a case of injury of a radial artery branch, a case of extensive haematoma, and two cases of neuropraxia. In three cases the procedure was converted into open surgery: they had a longer time of healing and a residual scar. The arthroscopic resection has been in our experience effective and safe for the treatment of all radiocarpal ganglia. Good results have been obtained also in the treatment of dorsal midcarpal ganglia. Concerning the uncommon cases of volar midcarpal (STT) ganglia, an open approach seems still indicated.
