Exam 2 Flashcards
Dull, aching pain. Aggravated by function. Trigger points elicit jump sign. Pain at remote sites
Myofascial Pain
Diffuse pain, usually continuous. Increased pain with movement. Limited movement due to pain/swelling.
Myositis
Acute pain at rest and w/ fxn. Continuous involuntary contraction. Limitation in fxn and often malocclusion.
Myospasms
Pain on function but not at rest. Limited range of motion (CNS).
Protective Muscle Splinting
Limited movement due to trismus/fibrosis. Usually not painful. Maybe result of protective muscle splinting.
Contracture
Abnormal enlargement of muscle. Usually not painful. Maybe result of parafunction.
Hypertrophy
New, abnormal and uncontrolled growth. Malignant/benign. Myxoma, myxosarcoma. May or may not be painful.
Neoplasm
Click, Disk and condyle no longer fxn as a unit. Clicking TMJ: condyle catches up w/ disk resulting in joint noises at various mandibular openings and “reduces”. Normal range of movt. May/may not be assoc’d w/ pain. If pain, localized in TMJ. May have deviated opening. May exhibit TMJ inflammation.
Disk Displacement with Reduction
Forward movt of condyle merely pushes disk forward. Limited opening (25-30 mm). If unilateral…deviation to affected side. Usually no TMJ noise. Usually painful. Restricted movt away from affected side. May exhibit TMJ inflammation.
Disk Displacement Without Reduction (closed lock)
Degenerative inflammatory condn. May exhibit crepitus (crackling sound). May be result of disk displacement. Usually radiographic evidence of bony changes
Osteoarthritis
Non-painful TMJ abnormality resulting in condylar changes
Osteoarthrosis
Systemic arthritic condition of several joints
Polyarthritides
