Definition Non-inflammatory focal degenerative disorder
of synovial joints, primarily affecting articular cartilage and sub-condylar bone; initiated by deterioration of articular soft-tissue cover and exposure of bone.
Clinical Features Crepitation sounds from joint(s) Restricted or normal mouth opening capacity Pain or no pain from joint areas and/or of
mastication muscles Occasionally, joints may show inflammatory
signs Women more frequent than men
![Page 25: CLINICAL SYMPTOMS](https://reader035.vdocuments.site/reader035/viewer/2022062808/5681544a550346895dc25ea9/html5/thumbnails/25.jpg)

Imaging Features•Abnormal signal on T2-weighted image fromcondyle marrow: increased signal indicates marrow edema; reduced signal indicates marrow sclerosis or fibrosis
•Combination of marrow edema signal and marrow sclerosis signal in condyle most reliable sign for histologic diagnosis of osteonecrosis
•Marrow sclerosis signal may indicate advancedosteoarthritis without osteonecrosis, or osteonecrosis

Make a “clicking” sound with the tongue on the roof of the mouth. This slightly opens the jaw with the tongue on the palate behind the front teeth, which is the resting position of the jaw and the first portion of relaxation exercises.
Place tip of tongue on palate behind teeth and draw small circles.
Place tip of tongue on hard palate and blow air out, rolling the tongue, or making a “r r r r” sound.
![Page 49: CLINICAL SYMPTOMS](https://reader035.vdocuments.site/reader035/viewer/2022062808/5681544a550346895dc25ea9/html5/thumbnails/49.jpg)
Begin with proper resting position of the jaw. Teach the patient control while elevating and depressing the mandible throughout the first half of the ROM.
Keeping the tongue on the roof of the mouth, the patient opens the mouth while trying to keep the chin in midline. Use a mirror for visual reinforcement.
If the jaw deviates to one side, teach the patient to practice lateral deviation to the opposite side without creating pain or excessive motion.

Irrigation solution is injected into the joint space to distend the capsule LR solution is preloaded in syringe w/needle attached.
After small stab incision is placed, surgeon inserts a sheath w/sharp obturator into superior joint space. After space is entered, the sharp is replaced with a dull obturator to further direct the sheath into the joint without damaging the intraarticular tissue or adjacent neurovascular structures. #11 blade with # 7 handle will be ready Trocar/cannula is preassembled. Expect trocor to be
returned. Be prepared to assist with connections of video/light cord connections.
