1

how many vertebra in cervical spine?

7

2

which 2 cervical vertebra are atypical?

atlas C1
axis C2

3

anatomy of atlas

no vertebral body
rotates around dens of C2

4

anatomy of axis

vertebral body of C2 extends superiorly to form dens

5

which vertebra in cervical spine are typical?

C3-C7

6

what is a vertebral segment?

one segment and the one below plus the NV

7

facets of the cervical spine

-facets are in a plane that points towards the eye in the uppers
-facets are pointing toward the opposite shoulder for the lower segments

8

C spine x rays

-need to see all 7

9

what are the 4 lines you need to look at the C spine x ray

-anterior vertebral line--they should all line up here
-posterior vertebral line--they should all line up here
-spinal laminar line--should all line up
-posterior spinous process line--should all line up

10

why do we get an oblique view of the C spine?

to see the spinal foramen and facets

11

cervical spine passive and active ROM

-starts in a neutral position
-palpate at C7 and T1
-have pt perform active motion first until motion palpated at your monitoring finger
-repeat for passive motion
-assess degrees of motin

12

ROM of flexion of C spine

45-90 deg

13

ROM of extension of C spine

45-90 deg

14

ROM of side bending of the C spine

45 deg in either direction

15

ROM of rotation of C spine

70-90 deg in either direction

16

biomechanics of the occipital atlantal joint

-this is the occiput moving on the atlas
-major motions here are flexion and extension
-shape of joint allows for more sagittal plane motion
-minor motions are SB and rotation
-occiput flex/ext + rotates and SB to opposite sides
-modified type I mechanics

17

cervical spine OA segmental diagnosis

-contact posterior aspect of occiput with middle finger and lateral aspect with index
-assess rotation R by lifting anterior on L
-assess rotation L by lifting anterior on R
-translate to L for R SB
-translate R for L SB
-reassess each in F and E
-modified type I mechanics
-OA F RR SL

18

biomechanics of AA joint

-atlantoaxial (AA or C1-2)
-primary motion is rotation
-atlas rotates about dens
-almost no SB or flexion/extension

19

cervical spine AA segmental diagnosis

-cup occiput and place fingers on AA joint
-fully flex head and neck to take out rotation of vertebra below AA
-rotate R
-rotate L
-is it symmetrical? is there ease of motion?
-AA RR

20

biomechanics of typical cervical segments (C2-7)

-rotation and SB to same side
-studies have noted clinically, SB and rotation to opposite sides
-currently thought to be due to compensatory patterns for dysfunction from lower parts of spine
-type II spinal mechanics

21

rotational diagnostic maneuvers of the typical C spine

-rotational
-transverse plane
-induce force ventrally on R lateral mass--rotate L
-induce force ventrally on L lateral mass--rotate R

22

translational diagnostic maneuvers of the typical C spine

-coronal plane
-translation from L to R--SB L
-translation from R to L--SB R

23

F and E with typical C spine

-recheck in F and E
-more restricted in F then E dysfunction--when segment is flexed the rotation or translation motions have a harder end feel
-more restricted in E then F dysfunction--when segment is extended then rotation or translation motions have a harder end feel
-change in sagittal plane will allow you to determine the segment is type II--you can infer SB with rotation testing or rotation with SB testing

24

where to document dysfunctions?

objective portion of SOAP
