Spinal mechanics- cervical spine

Question 1

Segmental movement

Answer 1

Overall, the Cspp has the greatest range of movement, across the whole spine

OA joint, is all about flexion/extension

C1, C2 is all about rotation (dens is used as a pivot)

C3, C4 has the greatest ROM for the whole cervical spine

Question 2

Roll, spin and glide concept available in the cervical spine

Answer 2

Occipital Atlanto (relies on the concave, convex complex)

– concave bone- atlas facet slides (passive)
– convex bone- occipital facet rolls (active)

so in the case of extension of the head, the occiput will roll posteriorly and the atlas will slide anteriorly

Question 3

Fryettes law

Answer 3

There will always be rotation to the same side when there is side bending

Question 4

Articular pillar

Answer 4

Modifications of the facets on the pedicles of the vertebra, and these facets have become thickened and widened

Question 5

The reasons RA can be a problem in the cervical spine

Answer 5

Inflammation an cause the ligaments (transverse) to be weakened, if this ligament is weakened, to can rupture causing the dens to ride up into the spinal cord causing paralysis.

Question 6

The reasons RA can be a problem in the cervical spine

Answer 6

Inflammation an cause the ligaments (transverse) to be weakened, if this ligament is weakened, to can rupture causing the dens to ride up into the spinal cord causing paralysis.
