Displacement of the disk occurs in three different directions: anteriorly, anteriomedially, and medially. The direction of the displacement is accompanied with reduction or without reduction. Reduction in the displacement is characterized by the articular disk returning to its’ initial, proper, position. If there is no reduction in the displacement, this means that the articular disk is always in the position described. Here are the different disk displacements that we will look at:

•Anterior disk displacement with reduction (ADD-WR)

•Anteriomedial disk displacement with reduction (AMDD-WR)

•Medial disk displacement with reduction (MDD-WR)

•Anterior disk displacement without reduction (ADD-WOR)

Anterior disk displacement with reduction is when the articular disk is in front of the condyle. During the opening phase, the disk slips in front of the condyle and on the closing phase, the disk snaps back into its proper position. This snapping motion is what seems to cause the clicking sounds that patients hear and feel. AMDD-WR is when the disk is displaced anteriorly and medially during the opening phase and snaps back to the correct position during the closing phase. MDD-WR is solely a medial displacement with reduction of the disk. Anterior disk displacement without reduction is more severe because the disk is permanently displaced in front of the condyle. This means during opening and closing the condyle will rotate and translate against the retrodiscal tissue which can cause a lot of pain to whomever it affects.
