Q

○ “Adhesions” causing a limited ROM
○ Intervention: First focus on decreasing the pain and then focus on the cause by providing therapeutic exercises

Q

○ Joint deflection into contralateral - opposite side since
it secretes more fluid and the fluid will deflect to the opposite side
○ Inflammation of synovium
○ The synovium as a response will secrete a fluid

12
Q

● The disc is moving downward
● Overstretching of the retrodiscal laminae
● It’s hard to go back to its own place, it remains obstructed anteriorly
● It limits ROM

13
Q

● The condyle moves first so the articular disc is pinched
producing a reciprocal click
● “Reduction” since it still goes back
● No changes in ROM but it implicates pain
○ The pain limits the ROM

Articular Disc Displacement with Reduction

A

Composed of the mandibular condyle and synovium
attached to the distal aspect of the disc

22
Q

Components of the superior compartment

A

Composed of the temporal fossa or eminence and the superior synovium attached to the disc
