Original language description

PURPOSE OF THE STUDY Scapholunate dissociation is a clinically most frequently diagnosed form of carpal instability. The aim of this study was to compare high resolution MRI using a microscopic coil with direct MRI arthrography in patients with suspected scapholunate ligament lesions and compare the results with arthroscopy findings and Geissler's arthroscopy classification. MATERIAL AND METHODS A prospective study was carried out in 47 patients (average age, 30.7 years) with clinical symptoms of wrist instability from 2013 to 2014. The patients were examined with the MR device Philips Achieva 1.5T using a microscopic coil and subsequently by direct MR arthrography. The results of examination were evaluated independently by two groups of physicians using a modified arthroscopic classification.The results were verified arthroscopically. For evaluation, an adjusted Geissler's classification was used. The study was approved by the Multicentre Ethics Committee of the Faculty of Medicine in Brno and informed consent was obtained from each patient.RESULTS A total of The MRI examination was evaluated and included in the study in 44 patients (three were excluded for the presence of motion artefacts). Only 20 patients underwent arthroscopy. Examination with a microscopic coil correctly classified 14 of them; an accuracy of 70 % (95 % CI: 45.7%-88.1 %) and p = 0.021. Direct MR arthrography correctly classified 16 of 20 injured ligaments, i.e., an accuracy of 80 % (95 % CI: 56.3%-94.3 %) and p = 0.002. DISCUSSION Currently, the diagnosis of pathological changes in the wrist is made by routine MRI especially when there is the possibility of using sequences with high spatial resolution. Even though we achieved poorer results by native examination using these techniques, when they were compared with the results of direct MR arthrography, they were still better than those reported in the recent literature.
