“…The musculoskeletal system is involved in nearly all patients with systemic lupus erythematosus (SLE), including arthralgias and arthritis as the most frequent manifestations. However, diverse tendon and ligament derangements have been sporadically reported as manifestations of SLE since 1975; these manifestations include tendinous laxity [1][2][3] , spontaneous tendon rupture 4,5 , Jaccoud's arthropathy 6,7 , atlantoaxial subluxation 1 , osteitis pubis 8 , and radiographic sacroiliitis [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] . Recent studies using powerful imaging techniques such as magnetic resonance imaging (MRI), highresolution ultrasonography, and power Doppler have demonstrated inflammatory pathology in the tendons of these patients [23][24][25] .…”
