Flashcards in Cervical Spine Deck (30):
1

Anterior Cervical Osteophytes

Common bony growths on the front of the spine
occasionally will push against the back of the throat and make swallowing difficult

2

Unilateral Facet Dislocation

the superior facet of the contralateral side moves anterior-superior over the tip of the inferior articular facet of the involved side, resulting in placement in the intervertebral foramen anterior to the inferior facet

3

Intervertebral foramina

serve as the principal routes of entry and exit for the neurovascular systems to and from the vertebral canal
vulnerable to narrowing with certain motions of ostephyte growth

4

Cervicothoracic junction

comprises the C7-T1 segment
forms the thoracic outlet through which the neurovascular structures of the upper extremities pass

5

Anterior Longitudinal Ligament

narrower in the upper c spines but wider in the lower c spine than in the thoracic

6

Posterior Longitudinal Ligament

the ligament is broader and considerably thicker in the cervical region than in the thoracic and lumbar regions

7

torticollis

aka wry neck
etiology varies and often cannot be defined
often associated with injury to SCM on one side
the muscles transformation into a fibrous cord that cannot lengthen

8

Whiplash syndrome

Hyperextension followed by hyperflexion
dynamic injuries to the spine cause a genuine pathological insult that causes prolonged distress and disability, often lasting for several years of after the accident

9

SCM

largest muscle in the anterior neck
Motor supply is from the accessory nerve and sensory from C2 and C3

10

Levator Scapulae

major stabilizer and elevator of the superior angle of the scapula

11

Clay Shoveler's Fracture

a type of hyperflexion avulsion injury
fracture of the spinous process at the base, caused by sudden exertions of the muscular attachments and can be caused by flexion injuries

12

where does a clay shoveler's fracture most commonly occur?

C7 > C6 > T1

13

Scalenes

extend obliquely like a ladder and share a critical relationship with the subclavian artery
adaptive shortening of these muscles will affect mobility in the upper c spine

14

Which muscle is implicated in thoracic outlet syndrome?

the scalenes

15

Thoracic Outlet syndrome

occurs when the size and shape of the outlet is compressed or narrowed
can happen because of posture, muscle tightness, exercise, trauma, pregnancy, or a cervical rib

16

Which muscles are tested when doing a C5 nerve root evaluation

Deltoid and biceps

17

What nerve innervates the deltoid

axillary nerve

18

which nerve innervates the biceps

musculocutaneous

19

Which muscles are tested when doing a C6 nerve root evaluation

wrist extension-
extensor carpi radialis longus and brevis, extensor carpi ulnaris

20

Which nerve innervates extensor carpi radialis longus & brevis, as well as extensor carpi ulnaris

radial

21

Which muscles are tested when doing a C7 nerve root evaluation

triceps
flexor carpi radialis, flexor carpi ulnaris
extensor digitorum communis, extensor indicis profundus, extensor digiti minimi

22

What nerve innervates the triceps?

radial

23

which nerve innervats flexor carpi radialis?

median

24

which nerve innervates flexor carpi ulnaris?

ulnar nerve

25

Which nerve innervates extensor digitorum communis, extensor indicis profundus, extensor digiti minimi?

radial

26

which muscles are tested when doing a C8 nerve root evaluation

flexor digitorum superficialis, flexor digitorus profundus, and the lumbricals

27

Which muscles are tested when doing a T1 nerve root evaluation

dorsal interossei, palmer interossei

28

which nerve innervates the dorsal and palmer interossei

ulnar nerve

29

Jefferson Fracture

aka burst
axial load/vertebral compression

30

Hangman's Fracture

fracture of pars interarticularis at C2 and disruption of C2-C3 junction
