Abstract

Objective: The aim of the present study is to assess carpal tunnel syndrome's (CTS's) ultrasonography (US) and magnetic reso-nance imaging (MRI) findings in patients with psoriatic arthritis (PsA) and compare them with healthy controls.Methods: Thirty-nine PsA and twenty-eight healthy volunteers were examined in this study. Demographic and clinical features were recorded. CTS-6, a diagnostic algorithm, was used to estimate the probability of CTS. Electrodiagnostic study (EDS) was applied to all wrists included in the report, where the diagnosis of CTS was made by EDS. The cross-sectional area (CSA) of the median nerve was measured at pisiform bone level by US and MRI.Results: Regarding to the demographic characteristics, no statistically significant difference was found between the groups. Twelve of 39 (30.76%) PsA patients had CTS, whereas CTS was not detected in the control group (p=0.001). US and MRI showed increased median nerve CSA in PsA patients compared to healthy controls (p=0.005, p<0.001; respectively). Also, US and MRI showed increased median nerve CSA in CTS patients compared to others (p=0.002, p<0.001; respectively). The Pearson correla-tion coefficient between MRI and US measurements of the CSA was 0.85 (p<0.001).Conclusion: CTS frequency in PsA patients is found higher than healthy controls. The relationship between CTS diagnosed by EDS and CSA measured by both US and MRI was observed in PsA patients.
