Dynamic Wrist Radiographs in Patients with and without a Ganglion Cyst

Abstract

Objectives The purpose of this study was to find out if carpal instability played a role in the etiology of ganglion cysts. Materials and Methods Dynamic wrist radiographs of 33 patients with and without a ganglion cyst of the wrist were compared. The control group consisted of patients who had dynamic radiographs of both wrists after a traumatic event in one wrist. Measurements were performed on the contralateral uninjured side. Radiological parameters that may indicate carpal instability included: width of the scapholunate gap, scapholunate, radiolunate, and lunocapitate angles, and ulnar translocation. Results No statistically significant difference was found between the two groups except for lunocapitate angle which was higher in wrists with ganglion cysts. However, mean lunocapitate angle was still within the normal range. Conclusions It could be concluded that in this study we did not see a difference between scapholunate gap and radiocarpal angles with the presence or absence of a ganglion cyst.

Abnormal Wrist Sagittal Kinematics in Gymnasts With Dorsal Wrist Pain: A New Syndrome

“…1 Previous reports on the relationship between wrist pain and an increased angle of the capitolunate joint are consistent with the results of our pain group. Beuckelaers and Hollevoet 5 reported that the angle of the capitolunate joint of the wrist with ganglion, one of the pathologies associated with dorsal wrist pain, was increased compared with that of the control group. In gymnasts with wrist pain evaluated with necrosis of the capitate, the articular surface of the capitate to the lunate was irregular and the capitolunate joint was enlarged.…”
