In rheumatoid arthritis (RA), forefoot bursitis is prevalent, with limited studies comparing ultrasonography (US)and Magnetic Resonance Imaging (MRI). This study aims to evaluate these bursae, providing a comparative analysis of USand MRI, and explore associations with demographic, disease-related factors, pain, clinical examination, and baropodometryin RA patients. Participants with RA were recruited from the day-hospital clinic. The forefeet wereassessed clinically, and the selected foot was examined by US and MRI to evaluate intermetatarsal (IMB) and submetatarsalbursitis (SMB). Baropodometry assessed plantar pressures and contact surfaces. Thirty-five RA patients were enrolled, 85.7% females, mean age 59.2 (11.3) years, mean body mass index (BMI) 26.5 (5.7) kg/m2, median disease duration of36.0 (16.5-114.0) months, and 34.3% with painful forefoot. A total of 140 intermetatarsal and 175 submetatarsal spaces wereevaluated. Agreement between US and MRI was high (PA=97.14%, k=0.801, p<0.001), and interobserver reliability for bothmodalities was excellent (US: PA=98.73%, k=0.888, p<0.001; MRI: PA=98.41%, k=0.900, p<0.001). IMB was negativelyassociated with disease duration (the only independent predictor) and linked to clinical signs like the opening toes sign andhammer toe deformity. SMB showed an association with BMI and erosions. Baropodometric analysis indicated no significantdifferences in plantar pressures for IMB, and larger contact surfaces in SMB regions. US and MRI are valuabletools for forefoot bursitis evaluation. IMB is associated with disease duration (negative association), the opening toes sign, andhammer toe deformity, while SMB correlates with BMI, erosions, and foot architectural deformity. Baropodometry revealedlarger contact surfaces in regions with SMB.
