title: [Arthroscopic treatment of dorsal wrist ganglia].
abstract: Incidentally discovered in 1987, arthroscopic treatment of dorsal wrist ganglia is based on our knowledge of their physiopathology which in turn benefits from the arthroscopic wrist evaluation. Dorsal wrist ganglia arise in the radiocarpal space from the dorsal part of the scapholunate ligament and migrate along the dorsal wrist capsule. According to their position above or under the dorsal intercarpal ligament, their cutaneous projection may vary. The basis of the arthroscopic treatment of wrist ganglia is, as with open surgery, the capsular resection in front of their origin. Arthroscopic resection is made either from dorsal radio-carpal or midcarpal approaches with little morbidity. Scars are unnoticeable, wrist mobility and strength close to normal by three months, which is the delay for dorsal wrist pain, always very limited, to disappear. The recurrence rate is however still debatable. Close to zero in some series, we had almost 20% recurrence rate in our series, with half of patients who reccur after two years follow-up. This variability in the recurrence rate also exists with open techniques. The only prospective and randomized study available to date found no differences between the two techniques, according to the recurrence rate.
