Öğe THE MRI FINDINGS IN PATIENTS WITH IDIOPATHIC CARPAL TUNNEL SYNDROME BEFORE AND AFTER TREATMENT(2019) Karaca, Şahika Burcu; Şahin, Rula; Karabekmez, Leman Günbey; Yetiş, Tevfik; Duran, NihalObjective: In this study, while evaluating the effectiveness of splint,injection, paraffin and surgical treatment with Magnetic ResonanceImaging (MRI) in patients with idiopathic carpal tunnel syndrome(CTS), we investigated the consistency between MRI measurementsperformed by different observers.Material and Methods: Boston questionnaires were evaluated, andthe cross-sectional areas (CSA) of the median nerve were measuredby two different observers, in 50 hands of 50 patients withidiopathic CTS.Results: The CSA of the median nerve at the radiocarpal joint levelof the canal were significantly larger than the values at the hamatelevel of the canal when values before treatment and three monthsafter treatment were compared (p<0.001; <0.001 respectively).Measurements of the CSA of the median nerve, taken by the firstobserver, were found to be significantly lower in the post-treatmentperiod at both the radiocarpal joint and hamate level, compared withthe pre-treatment period (p<0.001; 0.002 respectively).Measurements of CSA of the median nerve at the radiocarpal jointand hamate level performed by the observers in the pre- and posttreatment periods, were found to be highly compatible with oneanother.Conclusion: MRI is a valuable investigative technique for use withCTS patients, for the diagnosis of idiopathic CTS. When evaluatingthe efficacy of treatment, measurements of CSA of the median nerveare important, particularly at the proximal regions of the canal. Thecompatibility between the MRI measurements of the differentobservers, led us to consider that the measurements were objective.
