Temporomandibular Joint TMJ Anatomy and Disc Displacement Animation
The temporomandibular joint the tmj is the joint between the lower jawbone the mandible and the temporal bone of the skull.The tmj is responsible for jaw movement and is the most used joint in the body.The tmj is essentially the articulation between the condyle of the mandible and the mandibular fossa a socket in the temporal bone.The unique feature of the tmj is the articular disc a flexible and elastic cartilage that serves as a cushion between the two bone surfaces.The disc lacks nerve endings and blood vessels.
In its center and therefore is insensitive to pain.Anteriorly it attaches to lateral pterygoid muscle a muscle of chewing.Posteriorly it continues as retrodiscal tissue fully supplied with blood vessels and nerves.The mandible is the only bone that moves when the mouth opens.The first 20 mm opening involves only a rotational movement of the condyle within the socket.For the mouth to open wider, the condyle and the disc have to move out of the socket, forward and down the articular eminence, a convex bone surface located anteriorly.
To the socket.This movement is called translation.The most common disorder of the tmj is disc displacement, and in most of the cases, the disc is dislocated anteriorly.As the disc moves forward, the retrodiscal tissue is pulled in between the two bones.This can be very painful as this tissue is fully vascular and innervated, unlike the disc.The forward dislocated disc forms an obstacle for the condyle movement when the mouth is opening.In order to fully open the jaw, the condyle has to jump over the back end of the disc and onto its center.This produces a.
Clicking or popping sound.Upon closing, the condyle slides back out of the disc hence another click or pop.This condition is called disc displacement with reduction.In later stage of disc dislocation, the condyle stays behind the disc all the time, unable to get back onto the disc, the clicking sound disappeared but mouth opening is limited.This is usually the most symptomatic stage the jaw is said to be locked as it is unable to open wide.At this stage the condition is called disc displacement without reduction.
