A steep articular eminence has been proposed as an aetiological factor in internal derangement of the temporomandibular joint. Arthrograms of 20 joints each of three groups, superior disc position (SDP), anterior disc displacement with reduction (ADDWR) and anterior disc displacement without reduction (ADDWOR) were compared. No correlation was found between a steep articular eminence and anterior disc displacement. The posterior slope of the articular eminence of the joints with ADDWOR was significantly less prominent than in those with SDP and ADDWR.
陡峭的关节结节已被提出作为颞下颌关节内紊乱的一个病因因素。比较了三组（上盘位置（SDP）、可复性盘前移位（ADDWR）和不可复性盘前移位（ADDWOR））各20个关节的关节造影。未发现陡峭的关节结节与盘前移位之间存在相关性。ADDWOR关节的关节结节后斜面明显不如SDP和ADDWR关节的突出。
