Objectives/Interrogation: The exact pathophysiological mechanism of ganglion cysts of the wrist is still not completely understood. The aim of the study was to investigate if carpal instability plays a role.

Methods: Thirty-three patients with a dorsal or palmar ganglion of the wrist and 33 patients without cysts were included in the study. Standard anteroposterior and lateral radiographs of the wrist, clenched fist and anteroposterior views with the wrist in ulnar deviation were taken. Radiological parameters that may indicate carpal instability were measured and compared between the two groups, including: the width of the scapholunate joint space on anteroposterior views and the scapholunate, capitolunate and radiolunate angle on the lateral views.

Results and Conclusions: No statistical significant difference in scapholunate gap and scapholunate and radiolunate angle could be found between the two groups. Mean capitolunate angle measured 13.5° in wrists with a ganglion and 8.1° in wrists without. Although this difference was significant, the values were within the normal range.

Carpal instability may not play a role in the etiology of ganglion cysts.
