Cervical and Thoracic Spine Flashcards
What artery passes through the transverse process of the cervical vertebrae?
What is the name of this artery before it enters the C-spine?
What is the name of this artery after it passes through the foramen Magnum?
Vertebral Artery
Arises from Subclavian Artery
Becomes the basilar artery once it enters the foramen magnum
Where does the Alar Ligament attach?
What is the job of the Alar Ligament?
What Ligament helps support the Alar ligament
attaches at the dens and the occipital condyles
keeps the dens in close approximation to the C1 articulation and away from the spinal canal during motion
cruciform ligaments
What ligament attaches the C7 to the external occipital protuberance to increase the depth of the cervical spinous processes allowing for muscular attachment?
What motion does this ligament help limit?
ligamentum nuchae
helps limits excessive flexion of C spine

What percentage will have moderate disability and their symptoms will take longer to fully resolve or may never resolve?
What percentage will have severe disability and lead to chronic neck pain that doe snot reoslve?
~45% will have mild disability and symptoms resolve quickly
~40% will have mod disability
~15% will have severe disbaility
For patients who have acute traumatic neck pain via whiplash or similar MOIs, what time frame will they have the fastest progress in their recovery?
Within the first 6-12 weeks
The Neck Pain CPG states there are 5 main factors that lead to poor prognosis, what are they?
High Pain Intensity
High Disability
High post-traumatic symptoms
High Pain Catastrophizing
Hyperalgesia
How should you rate a patient’s pain intensity?
What level may be an indicator for poor prognosis?
Numerical Pain Rating Scale (NPRS)
over 6/10
How should you measure a patient’s disability for the C spine?
What level may be an indicator for poor prognosis?
Neck Disability Index
30% or higher=poor prognosis
How can you measure a patient’s post-traumatic symptoms?
What level may be an indicator for poor prognosis?
impact of events scale
over 33%=prognosis
How can you measure a patient’s pain catastrophizing symptoms?
What level may be an indicator for poor prognosis?
catastrophizing scale
over 20-poor prognosis
How can you measure hyperalgesia?
What level may be an indicator for poor prognosis?
cold presser test
it is hard to test but a positive result equals poor prognosis
What is the best way to diagnose cervical Myelopathy?
MRI
What are the five components of the clinical prediction rule for Cervical Myelopathy?
Gait Disturbances
Positive inverted supinator sign
Age over 45 years old
Positive Hoffman’s test
Positive Babinski sign
What is the best clinical course for patients who have 0/5 of the clinical predictors for cervical myelopathy?
1/5?
3/5?
4/5?
0/5- rule out cervical myelopathy
1/5 shows good sensitivity to rule out Cerv Myelopathy
3/5= a positive ratio of 36
4/5= infinite positive ratio and 9% post test probability leads to confidence in ruling in
What are the red flags associated with possibility of upper cervical ligamentous instability?
-any history of traumatic injury
-feelings of instability
-feeling like they need to assist their head with staying up
-myelopathy signs
-limited ROM
What are the red flags associated with carotid or vertebrobasilar artery insufficiency?
signs of a TIA (5 D’s And 3 N’s)
history of TIA
HTN
diabetes
clotting disorders
What are the 5 D’s And 3 N’s?
Dizziness
Diplopia
Dysphasia
Drop Attacks
Dysphagia
Ataxia
Nausea
Numbness
Nystagmus
What is Diplopia?
What is dysphasia?
What is dysphagia?
What is ataxia?
What are drop attacks?
double vision
impairment with speech
difficulty swallowing
impaired coordination
sudden fall with or without loss of conciousness
According to the Canadian C-Spine Rules what are the high risk factors for cervical fracture?
How many high risk factors need to be present for a patient to be referred for imaging?
-age over 65
-high speed MVA (over 62mph)
-fall from over 3 feet or 5 steps
-involved in a roll over
-paresthesia in BUEs following traumatic cause of pain
If ANY of these signs are present patient should be referred for imaging
A patient had a traumatic incident and you have started to use the Canadian C spine rules and found no high risk factors. You want to assess ROM of the C spine, what low risk factors do you have to screen for before you do that?
How do you use these factors to determine if ROM is safe?
-no mid-line tenderness
-patient is able to sit upright in ER
-patient is ambulatory
-MVA was a simple rear-end accident
-Delayed pain onset
If any one of these factors is present yo can assess ROM
If a patient has no high risk factors and has at least one low risk factor present you can assess ROM, what findings when assessing ROM would lead you to refer the back for imaging?
patient lacks 45 degrees of rotation on either side
What is the Nexus Criteria for cervical spine imaging?
states imaging should always be performed unless all 5 of the following criteria are met
-no evidence of mid-line tenderness
-no intoxication
-normal cognition
-no facial neuro deficiency
-no painful distracting injury
What are the common symptoms and exam findings for people who fit in the neck pain with mobility deficits classification?
Symptoms
-central and/or unilateral neck pain
