cervical Flashcards
Why is there a bifid spinous process in the mid cervical spine?
For attachement of ligamentum nuchae - except the transition to tpsine
Why is the angle of the articular process?
45 degrees
Foramen Transverasum
6th vert entry, and 1st very exit for vertebral artery
C/T junction level
C6
Transition to upper c/s
C2-3
Uncovertebral joints/Joint of vonlushka
Uncinated process to protect disc and stabilize c/s. Saddle joints. decrease disc herniations
Intra-articular inclusions
- Intra-articular fat pads (AO jt)
- Fibro-adipose meniscoid (not in AO)
- Capsular rims: wedge shapped
Function of zygapophysial joints
- Compensate for incongruency
- Distribute synovial fluid
- Preservation of articular edges
- Transmission of forces
- Fill space
Acute neck pain like due to
Zygapopgysial Joint dysfunction
Uncovertebral joints
- limit lateral bending
- guide flexion and extension
Bogduk: U joints
clefts facilitate rotation and SB in plain facet
Panjabi: U joints
Uncinate process protects against disc herniation
C1-3 anastamose with…
CN9 and 10.
Can refer up to C2-3, creating cervicogenic HA
C4 and below refer to
scapula
C7 refers to
top of 1st rib
McKenzie: Dysfunction
aberrant function of musculoskeletal system
McKenzie: Derangement
disc
McKenzie: Postural
time dependent
PLL
becomes thicker and forms the tectoral membrane in the upper c/s
Intratransverse lig
Stabilize AA segment and protects spinal cord from dens
Alar Lig
- Dens to occiput, stabilize dens.
- tightens with side cocking
Apical lig
- dens to occiput, holds dens to foramen magnum
- Has proprioceptive properties
Cruiciform lig
- transverse and longitudinal portions
- holds axis tight against atlas
- prevents anterior shear of axis
Ligamentum Nuchae
- Connections to spinal dura between Occiput-C2
- Innervated by upper c/s nerves
- Dense, bilaminar, tiangular midline fibroelastic intermuscular septum
- Occipital protuberence to spine of C7
