Example: if C6 is effected, so it will come out between C5/C6
C3-C7
Transverse Foramen: vertebral A
Small transverse process
Bifid Spinous process
Lateral Mass= Articular Pillar that we push on
C1
Atlas Dens articular facet Lateral Mass= Superior Articular Facet Transverse process (con be used to palpate) Posterior Tubercle (NO SPINOUS PROCESS) Vertebral foramen
C2
Axis Odontoid Process (DENS) Lateral Mass that we palpate= Inferior articular process Small transverse process Bifid Spinous process Vertebral Foramen
Vertebral Body
C1: none, has transverse alar ligament to wrap around the dens
C2: none, has dens
Dura has direct contact with
C2
Monotoring dura tension
Can play role at headaches or neck ridgidity
(Myodural Bridge) connects to rectus capitis posterior of C2
Hangman’s Fracture
Anterior vertebral line is distorted Pedicure fracture (vertebral arch is fractured) Due to hyper extension = spondylolisthesis
Unilateral Facet Joint dislocation
The spinous processes don’t line up and trachea is not midline
Atypical Articulations
OA and C1
C2- C7
Articulations
Rotation and side bending in SAME DIRECTION
(Due to uncinate process)
Flex ion and Extension can be painful= Spinous Arthritis
EX:if C4 is R left, then it is S left
OA Articulations
Occiput on C1
MOSTLY FLEXION AND EXTENSION (Sagittal motion)
Side bending and rotation in OPPOSITE Directions
AA joint C1/C2 articulations
Rotation around odontoid process
Capitis Inferior Muscle does this
(Almost no flex, ext, side bending)
ME
Patient pushes: indirect
Physician pushes: direct to barrier
Neck flexion degrees
45-90
Neck extension degrees
45-90
