ABSTRACT
PURPOSE: The purpose of this study was to verify the relationship between the residual pain and preoperative carpal instability, as well as the generalized laxity after open excision of wrist ganglion. MATERIALS AND METHODS: Sixty-four patients, who received open excision of wrist ganglion, were retrospectively enrolled. The relationships between residual pain (visual analogue scale, VAS) and postoperative function (quick disabilities of the arm, shoulder and hand, quick-DASH), between residual pain and preoperative carpal instability, as well as generalized laxity were evaluated. The carpal instability was assessed from radiologic carpal instability (dorsal intercalated segment instability and volar intercalated segment instability) and Watson scaphoid shift test. The generalized laxity was assessed by the Beighton hypermobility score. RESULTS: Pain VAS and quick-DASH were significantly improved postoperatively. There was a significant difference in postoperative residual pain between those with (n=6) and without carpal instability (n=58) (+: 2.50±1.76 vs. −: 1.18±1.24; p=0.022), but there was no correlation between carpal instability and postoperative quick-DASH. Both postoperative residual pain and quick-DASH had no correlation with generalized laxity (n=18). CONCLUSION: Patients with preoperative carpal instability had greater residual pain after excision of wrist ganglion than those without.

PURPOSE: To analyze the results of an arthroscopic resection of a wrist ganglion. MATERIALS AND METHODS: Seventeen cases were analyzed. Eleven cases were treated by arthroscopic resection and 6 cases were treated by an arthroscopic resection and a pull out extracapsular sac. For the functional evaluation, the level of pain, grip strength, range of motion and patient's satisfaction were analyzed. The average follow-up time was 22 months (10-38). RESULTS: In all patients, the functional results improved and all patients returned to work. No recurrence was noted. A ganglion stalk was identified in 14 cases, including 8 cases (scapholunate ligament), 3 cases (midcarpal joint), 1 cases (dual stalk), 1 case (lunotriquetral ligament) and 1 case (carpometacarpal joint). There was no case of Scapholunate instability and the scapholunate angle and gap were within the normal limits. CONCLUSION: An arthroscopic resection of a wrist ganglion is a safe and reliable alternative to an open resection.
