Arthroscopic resection of wrist ganglia: About 30 cases

The synovial wrist ganglion is a particularly common pathology of which the first "complication" is recidivism. The main objective of our study was to determine the rate of recurrence of this pathology in a series of arthroscopic patients. The secondary objective was to assess patient satisfaction well after the operation.

Our study was observational and retrospective and involved 30 patients (17 dorsal and 13 palmar cases) aged 41 years on average. The patients underwent an arthroscopic procedure for a palmar or dorsal ganglion of the wrist between March 2007 and April 2013. The data were collected by re-reading the files and conducting telephone interviews. Each patient answered a questionnaire about the operation, after-treatment, and their satisfaction well after the surgery. At the end of the interview, we calculated the Patient Rated Wrist Evaluation (PRWE) score.

The mean follow-up was 4.6 years. A recurrence was noted in 4 (13%) cases, at an average delay of 9 months (6 months-1 year). There were only 2 patients (6.7%) that experienced the complication of complex regional pain syndrome type 1. Twenty-eight (93%) patients experienced improvement in postoperative pain. For 27 (90%) patients, firm-handed activities could be practised without limitation. The average time to resumption of activities of daily living was 27.1 days (1-240 days), resumption of firm-handed activities was 56 days (15-360 days), and return to work was 47.5 days (1-360 days). The mean PRWE score was 6.9/50 (0-34) for pain and 1.38/50 (0-8) for function.

The 13% recurrence rate is on the average of what is observed in the literature. Later satisfaction with the intervention is very good, and complications remain rare.Studies tend to show a lower rate of complications and recurrence following arthroscopic treatment, but to date, no randomized comparative series between the two methods has yet revealed any significant difference in these two points. A study of this type on a large scale could make it possible to highlight one of these treatment approaches.
