To assess the position of temporomandibular joint (TMJ) disc in patients with TMJ pain and compare it equivalent published data asymptomatic volunteers.The oblique coronal closed- open-jaw MR images from 66 were evaluated. Clinical examination followed research diagnostic criteria for disorders. In all images, transverse condylar axis medial lateral edges determined using special software. Inter-rater agreement was calculated [two raters; inter-rater correlation coefficient (ICC)]. The presence osteoarthrosis (OA) by two independent raters. influence OA estimated (generalized estimation equation model). results compared those healthy volunteers (t-test). Differences between closed open jaw analysed Wilcoxon matched-pair test.The ICC good (0.987) edge (0.799) fair (0.355). On average, projected 5.5% to side; laterally, condyle partially uncovered (-16.6%). position, both shifted medially (to 17.6% vs -23.6%, test, p < 0.001). had no significant model, = 0.952). differed significantly individuals (t-test, 0.001) who showed a full coverage condyle.In pain, seems be smaller located less than volunteers. extent shift on opening similar.
