In a blind study, 243 arthrograms were interpreted as showing normal disk position, anterior disk displacement with reduction, or anterior disk displacement without reduction. The presence or absence of a perforation of the posterior attachment or disk was recorded. Later, tomograms of the same patient were interpreted. The presence or absence of evidence of temporomandibular degenerative joint disease (TMDJD) was recorded. The condyle-to-fossa relationship was characterized as retropositioned or not retropositioned. O the 106 cases with tomographic evidence of TMDJD, 100 (94%) had arthrographic evidence of internal derangement (p less than 0.0001), whereas 47% of the cases with internal derangement (211) had evidence of TMDJD. Perforations were seen in 29 (27%) of the cases with degenerative joint disease and in none (0%) of the cases without TMDJD (p less than 0.001). In cases without TMDJD, 90% of the cases with internal derangement revealed condylar retropositioning (p less than 0.0001). With tomographic evidence of TMDJD present, the relationship between condylar position and disk position was not significant.
在一项盲法研究中，对243例关节造影进行解读，结果显示为正常盘位置、可复性盘前移位或不可复性盘前移位。记录后附着或盘有无穿孔情况。随后，对同一患者的体层摄影片进行解读，记录有无颞下颌关节退行性关节病（TMDJD）的证据。髁突与关节窝的关系分为后移位或无后移位。在106例有TMDJD体层摄影证据的病例中，100例（94%）有关节造影显示关节内紊乱的证据（p<0.0001），而在211例有关节内紊乱的病例中，47%有TMDJD的证据。在有退行性关节病的病例中，29例（27%）可见穿孔，而在无TMDJD的病例中未见穿孔（0%）（p<0.001）。在无TMDJD的病例中，90%有关节内紊乱的病例显示髁突后移位（p<0.0001）。有TMDJD体层摄影证据时，则髁突位置与盘位置之间的关系不显著。
