[Arthroscopic treatment of dorsal ganglion cyst at the wrist. About 54 cases].
BACKGROUND
Ganglion cyst of the wrist can, some time, need surgery. Different arthroscopic technical procedures have been described. We report our experience in all articular resection of dorsal ganglion cyst of the wrist.


OBJECTIVE
Evaluation of efficiency of resection of dorsal ganglion cyst of the wrist by of arthroscopic resection of the pedicle.


METHODS
Fifty-four cysts of 52 patients have been evaluated retrospectively. Operative data, pain, strength, recurrence and complications have been collected.


RESULTS
Average follow up was 28 months (6 to 78). Return to work was 8,8 days, operative time 41 minutes (25 to 90). In 67% cases, the operation was judged easy. Three surgeries had to be performed open. Complications were one hematoma and one neurodystrophy. Pain decrease from 3,37 to 1,76 on analogical pain scale. Flexion was 89% of opposite side, extension 88%. Sixteen recurrences (29.7%) were found. Sixty percent of those recurrences occurred during the first year experience. But independently of experience, the operative performance was foun difficult in 1 time on 3.


CONCLUSIONS
Endoarticular arthroscopic resection of the pedicle of ganglion cyst is not so reproducible. In experimented hands, it remains a difficult procedure after a long learning curve with a recurrence rate 3 times higher from what is reported in literature for open surgery. For our discharge, our long follow-up can contain some cases of de novo cyst explaining this high rate, the learning curve is certainly the main reason for our high recurrence.
