OCS EXAM 4 HIGH-YIELD JOINT
EXAMINATION, REHABILITATION PRINCIPLES,
AND ORTHOPEDIC DIAGNOSIS SUMMARY
2026
◉ Where are the joints of Luschka located?
Answer: c-spine C3-7 and these jts are commonly assoc with
degenerative spine conditions and cervical radiculopathy
◉ What part of the cervical intervertebral discs is the weakest?
Answer: posterior; the annulus fibrosis is thick anteriorly but thin
and weak posteriorly
◉ During passive cervical rotation to the right, where does the
vertebral artery get compressed?
Answer: between the first and second cervical vertebra on the left
◉ What are absolute contraindications for manual therapy?
Answer: Osteomyelitis
Nerve Root Compression with increasing neuro deficits
Influenze with Fever
,Pregnancy is a relative one!
◉ Pt's who are not good for cervical manipulation include?
Answer: radicular sx to mid-forearm
these people would do better with centralization techniques
severe spondylosis without radic are ok
◉ During Cervical Artery Dissection, which arteries would you
suspect to be involved?
Answer: Vertebrobasilar, which is the posterior arterial system
perfusing the hindbrain and the internal carotid artery which is the
anterior arterial system perfusing the cerebral hemispheres and
eyes
◉ Trying to differentiate if a pt's dizziness is 2/2 to a cervical artery
dissection or non-vascular vestibular dizziness. What would you
expect if te pt had dizziness 2/2 cervical artery dissection, rather
that non-vascular vestibular dizziness
Answer: -dizziness is reproduced with active cervical rotation and
active trunk rotation with head stable
,-if pt's dizziness is 2/2 vestibular disorder you'd expect dizziness to
be reproducible with active cervical rotation but not trunk rotation
since the vestibular canals remain unchanged in this position
◉ If your pt has neck pain starts to develop symptoms related to
hindbrain ischemia, all of the following CN would likely be involved
expect
Answer: CN 1, 2
◉ Acute dissection of Internal Carotid, what CN is involved?
Answer: CN 12
◉ What CN's would NOT be effected with Internal Carotid
Dissection?
Answer: CN 1 (olfactory)
2-4 can be
◉ Which syndrome is common after Internal Carotid dissection and
results is ptosis, miosis, anhidrosis and enopthalmosis?
Answer: Horner's Syndrome
◉ What kind of malignancy will cause radiculopathy in C8-T1 nerve
distribution? What visceral structure?
, Answer: Pancoast Tumor
Heart
◉ What is the best intervention for cervical radic?
Answer: Intermittent mechanical traction
◉ What should you be thinking about when determining
spondylosis vs radic?
Answer: AGE
older age suspect spondylosis over a HNP C8-T1
arthritic changes are more common in the cervical spine than the
thoracic/lumbar. Disc herniations are common in the lumbar.
◉ Describe the AIN in terms of Presentation
Answer: no sensory sx
weakness of FPL and FDP and Pronator Quadratus
= inability to make OK sign
DDX: FPL rupture
◉ What nerve pathology can result in AIN s/s and inability to bring
thumb and tip of finger together?
Answer: Parsonage Turner Syndrome
