Cervical Supplementary Questions Flashcards
What are the stabilisation features of the cervical spine- bony structures?
Bony structures- odontoid process, SP’s, TP’s, intervertebral discs, atlas (support weight of the head), axis (rotation of the head).
What are the stabilisation features of the cervical spine- ligaments structures?
Ligaments- nuchal, alar, transberse liagments of the atlas, anterior and posterior longitudinal, interspinous ligament
What are the stabilisation features of the cervical spine- muslces?
Muscles- levator scapula, upper trapexius, sternocleidomastoid, scalene, erector spinae,
What structures limit cervical rotation?
Articular facets- once you get to end ROM there is a bone on bone end feel
Ligaments- flavum, interspinous, alar and transverse liagmnat due to the limited elasticity of these ligaments
Muscles- the scalene and sternocleidomastoid are unable to contract/lenegthen any further to aid furtehr movement.
Bony Deformities- if the dens is miss shaped it can limit ROM of rotation
what limits extension of the cervical spine?
Bony structures- SP’s of C2-C7, the movement will be stopped by the articulation of the superior SP with the inferior SP
Facet Joints- closed pack postion
Tightness of flexor muscles- unable to elongate
Weak extensor muscles- limited contraction
Anterior longitudinal ligament
what is the ROM for cervical rotation?
70-90 degrees
what is the ROM for cervical flexion?
80-90 degrees
what is the ROM for cervical extension?
70 extension
What is the end feel concept for side flexion?
Elastic/Firm end feel
This is because it is the muscles, ligaments and tendons on the opposite side that limit this movement
*Potential hard end feel is there are degenerative discs- thsi will cause veretbra to merge (bone on bone)
where is movement is taking place during retraction/flexion?
at the Atlanto-occipital joint at the base of the skull
what is the ROM for side flexion?
25 degrees
