Internal derangement related to osteoarthrosis in temporomandibular joint autopsy specimens.
In 127 temporomandibular joint autopsy specimens the position (superior 44%, partially anterior 22%, completely anterior 34%) and configuration of the disk (biconcave 56%, biconvex 10%, others 34%) were related to osteoarthrosis. All biconvex disks were positioned anteriorly and associated with osteoarthrosis. Biconcave disks were mostly positioned superiorly and associated with normal surfaces.
