Comparative results of arthroscopic versus open excision of dorsal wrist synovial ganglions

Abstract

Introduction:The purpose of this study was to compare the morbidity, functional outcomes and rates of recurrence of arthroscopic versus open excision of dorsal wrist ganglions. Methods: Forty patients with dorsal wrist ganglions were concerned. They were divided into two groups (A and B). In group A there were 25 patients treated by open excision and 15 other patients in group B by arthroscopic excision. Both groups were followed up in average 12 months (range, 9-18 months). The functional outcomes and rates of recurrence were recorded. Results: One recurrence (4%) was observed in group A and 2 recurrences (13.13%) in group B. Wrist active range of motion and grip strength were significantly higher in group B (p<0.001). Three patients (12%) had residual pain in group A and 2 patients (13.13%) in group B. Mean time off work was 15 days in group A and 8 days in group B. All patients in group B were satisfied with cosmetic result. Conclusion: Arthroscopic excision of dorsal wrist ganglion is increasingly performed but remains behind the historical and standard open excision. The duration of the procedure, the cost of surgical materiel, and the learning curve are the main obstacles for the development of arthroscopic excision.
