cervical arterial dysfunction def and pathogenesis

internal tear w/in blood vessel wall wherein blood starts to fill in or clot (occluding or dissecting aneurysm)
-predisposition via underlying abnormality in arteries ( vertebral and internal carotid are common)
-trigger of infection (ex: dental abscess) or trauma

pathophysiology of myelopathy

SC compression from impinging structures; related but not synonymous with stenosis

Perfectly

epidemiology and symptoms of myelopathy

present in 90% of ppl by 60 y/o, often PLL is ossified
Imbalance/fall hx, neck pain/stiffness, UE (dysesthesia), may involve LEs first (gait,weakness)

general cervical spine myelopathy examination

s/s: gait impairment, spasticity, pathologic reflexes, hyperreflexia, incoordination, radicular signs that can be sensory and or weakness (unilat/bilat) , balance impairment

Perfectly

cervical myelopathy CPR (3/5=99%)

gait deviation, Hoffmann’s sign, Inverted supinator, Babinksi’s, >45 y/o

what are the 2 main contributors to upper cervical instability?

ligamentous deficit(concomitant connective tissue dx, trauma) and fracture (fatigue, trauma)

Pathogenesis of cervical ligament instability

trauma/surgery, and congenital collagenous dx, throat infection, inflammation

upper cervical instability symptomatology

neck pain, occipital HA/numbness, limited activities @ end range ROM, radicular OR myelopathic s/s, positional intolerance

cervical instability examination (minus special tests)

ROM: multidirectional lim, w/ potential guarding
potential radicular or myelopathic signs

common tests for upper cervical instability (may not even need to perform all of them)

Modified Sharp/purser (transverse lig) , alar ligament stability test, lateral shear, tectorial membrane, Posterior A-O

jefferson fracture

4 part burst of atlas bone (most commonly due to compression), screen other c-spine injuries too!

define spondylolysis

defect of pars interarticularis (area between sup and inf processes)

define spondylolisthesis.What is the most common location?

forward/backward translation of one vertebra on another (anterior is most common esp @ c3/4 and c4/5); can be graded I-V

what are the Canadian C-spine rules and what do they help us to decide?

they help us screen for if we need radiography High risk? (>65y/o, dangerous MOA, extremity paresthesia) Low risk? (simple rear-end collision, sitting in ER, ambulation, delayed pain, absent tenderness) AROM? (at least 45* bilat)

what is the NEXUS low risk rule and who uses it?

typically immediate post-trauma (think ER and urgent care) -no midline cervical tenderness -no focal neurologic deficit (radicular/myelopathic ) -no intoxication -no painful/distracting injury -normal alertness

define spondylosis

when osteophyte complexes form around vertebrae body margins,hence it also affects discs

what are the 2 types of degenerative arthropathies?

spondylosis and osteoarthritis (typically @ AA and facet joints)

what are the 2 types of degenerative spinal stenosis?

lateral and central canal

describe complications related to central canal stenosis.

myelopathy, z-joint hypertrophy, bulging disc, thickening/ossification of ligament, spondylolysthesis

describe complications related to lateral canal stenosis.

loss ofo disc height, facet and uncovertebral joint hypertrophy, spondylolisthesis, and potential radicular pain or radiculopathy (check sensory AND motor)

what is the common MOI for acute z-joint arthropathy? What should we include in an examination for it?

Extension MOI -pain w/ compression ROM (think lat flex, rotation,ext) -pain w/ segmental provocation (P-As, U-Ps) -potentially positive cervical compression & Spurling (IF RADICULAR)sd

define somatic referred pain

relatively localized pain perceived by one anatomic location that is innervated by nerves other than that of the true source (convergenge of 2 CNS regions)

define radicular pain

pain related to nerve root irritation perceived in dermatome distribution often when closing on foramen, w/ or without radiculopathy, can aso be inflmmed (radiculitis)

define radiculopathy

conduction block> motor weakness,hyporeflexia, and dysesthesia;

what c-spine region is most commonly impacted by radiculopathy?

C6 and C7 > spondylosis w/ foraminal encroachment in most cases; can be traumatic or gegenerative

what s/s might be present in a pt with cervical radiculopathy?

Bakody's sign, pain/lim ROM w/ compressed foramen or stretched nerve root, positive valsalva, wainner's cluster

what is wainner's cluster?

ipsilateral c-spine rotation<60 deg, + Spurling's, +Cervical distraction, ULTT

describe the 3 main components of the mechanics behind whiplash associated dx

trunk thrust upward, lower c-spine rotation, a distracted annulus w/ impaction on facet

what are some s/s that might cue you into a whiplash associated dx?

HISTORY!, post-concussive sx (ex. tinnitus, visual deficits, dizziness), myotomal weakness, radicular or referred sx, glove like paresthesia, neck or UE pain and limited ROM,

what nucleus do cervicogenic headaches originate from?

trigeminocervical (frontal, orbital and parietal referral meet C1-C3), over half follow whiplash occurrence.

criteria of dx cervicogenic headache 1+5:possible >/=3: probable

1.unilateral HA that doesn't switch 2. s/s neck involvement 3.fluctuating episodes 4.mod, non-excruciating throb 5. pain from neck>>oculo, frontal, temporal 6. anaesthetic bock works 7. ANS s/s + sensory changes (vision, sound)

what other dx may need to be tested before confirming a cervicogenic dx?

migraine, dissecting aneurysm, posterior cranial fossa lesion, greater occipital neuralgia, neck-tongue syndrome, C2 neuralgia

what are the 3 proposed pathophysiologic mechanisms of cervicogenic dizziness

ischemic process impacting vertebrobasilar system, irritation of cervical SNS>vasomotor changes, altered proprio from upper c-spine
