Opportunities of ultrasound diagnostics of joint lesion in reactive arthritis
Features of ultrasonic diagnostics of joint and juxta-articular lesions were studied. 24 patients with reactive arthritis and 20 persons from control group were examined. It is established, that the ultrasonic research in comparison with radiological method is more informative for reactive arthritis diagnostics, as it allows us to estimate a condition of the ligamental apparatus, juxta-articular tendons and tissues. On the basis of the identified features of joint and juxta-articular lesions, ultrasonic criteria of reactive arthritis are defined: thickening, heterogeneity of structure, echogenicity reduction of entheses, ligaments, and development of closing plate osteofluence (erosion) in a place of entheses attachment.
