Background Rheumatoid arthritis (RA) is a chronic, inflammatory and multiple-system disorder of connective tissue leading to damage, deformation and functional impairment of joints. It frequently affects joints and periarticular structures of feet that constitute a significant supporting element underlying normal gait and motion of the body centre of gravity.
Objectives The aim of the study was to evaluate foot deformities on the basis of plantoconturographic examination in a group of patients with RA according to the severity of the disease.
Methods The study was performed on 54 patients (43 women and 11 men). The control group consisted of 34 volunteers free of any disorders of the musculoskeletal system. Plantoconturographic examination was carried out by means of a CQST2K podoscope. The following parameters were applied to the assessment of the disturbances of foot statics: hallux valgus angle (α), Sztriter-Godunow index (KY), Wejsflog’s index (Wwp) and Clarke’s angle (CL).
Results Markedly higher values of the alpha angle have been noted in RA patients in comparison with a control group. Moreover, values of the alpha angle were higher in patients in the third stage of radiological changes than those in the second one. On the other hand, values of the Clarke’s angle for the right foot were considerably higher in men in the second and third stage of RA compared to the control group.
Conclusions Plantoconturographic examination can be consider as an to constitute a useful diagnostic tool for assessment and monitoring of foot deformities in RA patients. The most common deformities in RA patients include hallux valgus and transverse flat foot.
