CERVICAL Flashcards
Cervicocephalic
C0-C2
upper cervical spine
Cervicobrachial
C3-C7
lower cervical spine
Where greatest flexion-extension occurs
C5-C6
OPP
midway between flexion and extension
CPP
full extension
CP
side flexion and rotation> extension
Joints of Luschka or Uncinate Process
limits extension
IV discs
makes 25% of height
none in C1-C2
gives lordotic shape
Nucleus Pulposus
inner layer
compressive forces
Annulus Fibrosus
outer layer
tension
Atlanto-occipital Joint
yes joint
C0-C2 (occipital condyles and atlas)
Atlanto-Occipital Joint Actions
side flexion: 10
flexion-extension: 15-20
negligible rotation
ellipsoid
Alar Ligaments
limits flexion and rotation
major stabilizing ligament of C1-C2
Atlanto-axial Joint
no joint
C1-C2
Atlanto-axial Actions
flexion-extension: 10 deg
side flexion: 5 deg
rotation: 50 deg
pivot joint
Vertebral Artery
passes transverse process, starting at C6, entering as high as C4
20% of blood along with ICA (80%)
Movements stressing the Vertebral Artery
rotation and extension: 20
significant decrease in blood flow
4 areas where vertebral artery is greatly stressed
- transverse process of C1
- bony canals of vertebral transverse processes
- between C1-C2
- C1 going to the skull
Cervical Spondylosis
> 25 y/o
inc to 60%= 45 y/o
inc to 85%= >65 y/o
Cervical Disc Herniation
17-60
Cervical Spinal Stenosis
11-60 (30-60)
Hypertension
vertebrobasilar insufficiency
big red flag
Diabetes affecting blood
thickened blood causes nerve ischemia
Asthma (muscles)
tightness of scalenes
hypertrophy of SCM
Headaches
cervicogenic, unilateral; C1-C3
muscle tightness in the occiput
Bilateral Headache
systemic
What to ask when headache is present?
how long does it last
what triggers
relieving factors in postural change
check for temporal pattern, behavior, medications
Headache + Vomiting
vertigo
vestibular system
fluids are not balanced
Dizziness
vertebrobasilar affectation
Headache secondary to trauma
positional change won’t cause relief= normal
Atraumatic headache
positional change won’t relief= systemic/ malignancy
