- Abstract
Arthroscopic ganglion resection provides a means by which dorsal wrist ganglia may be safely resected while avoiding the requisite scar accompanying open resection. Use of the arthroscope provides a much more complete examination of the wrist, allowing assessment of the cause of the ganglion as well as associated intra-articular problems. In a previous pilot study, 50% of patients demonstrated visible intra-articular abnormalities, including SL ligament laxity and perforations, TFCC tears, or chondral degeneration at the radial and triquetral-hamate joints. Use of the shaver within the joint allows the surgeon to directly address the ganglion's site of capsular origin, ensuring that the "one-way valve" mechanism is resected. The authors' initial experience was that the recurrence rate after arthroscopic resection was equal to or lower than after open resection. There is now some suggestion that resection of only the ganglion stalk, without removal of the sac, is feasible, but may yield slightly higher recurrence rates than formal open resection of the sac and stalk. This may be attributed to cases in which the capsular attachment to the SL ligament is debrided without identification and removal of a true stalk. The recurrence rate of a ganglion that has previously recurred also appears to be higher than that of primary resection. The authors look forward to publishing their completed results of an on-going follow-up study comparing open, arthroscopic, and recurrent ganglion resections.
