Cervical Spine Flashcards
Divisions of Cervical Spine
Cervicoencephalic/cervicocranial/craniovertebral
atlanto-occipital (C0-C1)
Antlanto-axial (C1-C2)
Cervicobrachial (C3-C7)
Majority of cervical rot. Occurs here
Cervicocephalic Region
more ligaments found this area compared to cervicobrachial area
Cervicocephalic Region
Cervicocephalic Region, Injury can lead to:
cognitive dysfunction :?
cranial nerve dysfunction : ?
sympathetic system dysfunction
Injury can lead to:
cognitive dysfunction : slower to response
cranial nerve dysfunction : brainstem
sympathetic system dysfunction
Most mobile articulations of spine
Atlanto-axial
Connects C2 to C0 (ligament)
Tectorial Membrane
Hangman’s fracture may occur at what level of the cervical region?
C2
Atlanto-axial, Principal motion:
Flex - Extend (?? deg) ;
side flexion (?? deg) ;
Rotation (?? deg) primary movement
Flex - Extend (10 deg) ;
side flexion (5 deg) ;
Rotation (50 deg) primary movement
COMMON SITE OF ARTHRITIS in the cervical region
RA - C4 & C5
OA - C5 & C6
jefferson’s fracture is located at what level of the cervical region?
C1
T or F
C5 - C7 most mobile (Whole Cervical Region)
FALSE
C5 - C6 most mobile (Whole Cervical Region)
Clay Shoveler’s fracture may occur at what level of the cervical region?
C7
Tests the integrity of the tectorial membrane
Pettman’s Distraction Test
make up 25% of cervical spine height
lordotic shape of cervical spine
Intervertebral discs
CERVICOBRACHIAL REGION is C?-C?
CERVICOBRACHIAL REGION involved C3-C7
Intervertebral discs
Inner portion = ??
Outer Portion = ???
*There is no disc between occiput and c1, even in c1 and c2
Inner portion = Nucleus Pulposus
Outer Portion = Annulus Fibrosus
There is no disc between occiput and c1, even in c1 and c2
T or F
Disc = segment above
Nerve = Segment below
TRUE
Spondylolysis is ?
Pain: Unilateral or Bilateral?
Spondylolysis is a stress fracture through the pars interarticularis of the lumbar vertebrae’
Pain: Unilateral
Spondylosis occurs beacuse of?
Disc thins
Wear and tear, Age, occupational factors
