Q

What x-ray view would you look at if someone had trauma or you’re concerned about stability?

Why this view?

A

Lateral! this way you can see the interval between C1 and C2. If its widened (>2mm) this shows there was attenuation of the transverse ligament

C1 has slipped anteriorly causing a gap and possibly shearing the SC

27
Q

What happens when you lose the spacer function of the IV disc?

A

you lose the vertical component to the vertebrae therefore making the IV foramen that the nerve is traveling through smaller. AND the ligaments are on slack (passive stabilizers of the system)

35
Q

When are we most susceptible to instability in the Cspine? and why?

A

30-40’s because there has been dysfunction due to disc changes but the body hasn’t caught up to making osteophytes to try to stabilize it yet.

37
Q

is isolated testing of the cspine musculature possible?

A

No

38
Q

To assess length of the muscles how do you need to move? Why?

A

in 3D plane because muscles are obliquely oriented

39
Q

super close to midline so mostly just flexion but also a little rotation contralaterally

What are their primeary action?

A

Scalenes

Lateral bending

49
Q

Function?

A

anterior

Cervical flexors but not a big moment arm, work to compress and stabilize

50
Q

What are the active stabilizers of the Cspine?

A

muscles! just the osteoligamentous structure of Cspine will collapse under just 2.5 lbs.

51
Q

Upper cervical motion is _____ relative to ____

A

head relative to neck

52
Q

lower cspine motion is _____ relative to ______

A

neck relative to trunk

53
Q

What moves first in flexion and extension upper or lower cspine

A

upper: think about nodding

54
Q

True or false, the upper and lower cspine can move independently from one another as well as together?

A

true

55
Q

Chin tuck

Upper cspine
Lower cspine

A

Upper: flexion
Lower: extension

56
Q

What movements have the most motion in the cspine. Where does it occur t/o? where does it peak?

A

flexion and extension

motion is distributed t/o

A lot in upper cspine as well as C4,5,6 (4,5,6 is the most common area for degeneration)

57
Q

what actions does the least total motion happen with in the cspine

What level does it happen the most at?

A

lateral bending

Occurs at all levels but mostly middle of the c-spine

58
Q

Where does the most rotation occur in the Cspine?

Where does it minimally occur?

A

50% between C1 and C2 but happens at all levels

Minimally at occiput and C1

59
Q

Upper thoracic spine is an extension what?

A

lower cspine: however in thoracic flexion and extension is limited due to rib cage

60
Q

what should you see with the lordosis of the spine when someone flexes their head?

A

curve reversal

61
Q

When you flex, what happens to the inferior facet in comparison to the superior fact?

A

sliding up the hill

62
Q

in flexion or extension is the INFERIOR facet sliding up the hill of the corresponding superior facet?

A

flexion

63
Q

What is the motion that should be seen most at the cpspine if the individual is not unstable?

A

rotation rather than translation. Excessive translation is a sign of instability.

64
Q

Biomechanics of flexion
Upper segment rotates: anteriorly or posteriorly

Slides: forward or back?

IV foramen and spinal canal widen or collapse?

Posterior elements compressed or tensed?

A

FLEXION

upper segment rotates anteriorly and slides forward

IV foramen and spinal canal widen

Posterior elements are put on compression stress

65
Q

Extension biomechanics
upper segment in relation to lower segment

Rotates: anteriorly, posterior?

Slides: forward or back?

IV foramen and spinal canal widen or collapse?

Posterior elements compressed or tensed?

A

EXTENSION

Upper segment rotates posteriorly and slides back

IV foramen and spinal canal collapse

Posterior elements have compression stress

66
Q

What is the axis of motion in a normal neck?

when does this change

A

posterior 1/3 of the disc

this changes when there are degenerative changes

67
Q

In flexion and extension as a posterior structure unit what is going on

A

muscles, nerves, ligaments etc are all going for the ride, its like an accordion

flexion: tension
extension: slack

68
Q

In the LOWER cspine what motions are coupled?

A

lateral bending and rotation

69
Q

What part of the cspine are rotation and lateral bending coupled?

A

Lower Cspine

70
Q

Why are we able to keep our eyes facing forward when we side bend if rotation and lateral bending are coupled int he lower Cspine

A

upper cspine compensates and rotates the opposite direction

71
Q

If a pt cannot rotate to the L what could you ask them to do to determine if its a limitation in upper or lower cspine?

A

have them side bend to the R, if they cannot keep their eyes forward then you know its the upper cspine limiting them because it should be compensating for the R sidebend and rotation being coupled in the lower cspine

72
Q

Test to isolate the upper cspine:

A

flexion rotation test, maximally flex them then rotate

73
Q

Vertebral body degeneration is called what?

A

spondylosis

74
Q

At what age is spondylosis incredibly common

A

> age of 60

75
Q

What should there be with compressive syndromes other than a radiograph that shows spondylosis we know doesn’t correlate?

A

there should be neurologic symptoms! just pressure on a nerve doesn’t hurt, it can cause numbness and parenthesia but not pain. Inflammation hurts

76
Q

True or false: pain is evidence of nerve compression?

A

False! there need to be neurologic symptoms (parensthesia, anesthesia, loss of motor function or reflex, clonus)

77
Q

What has decent correlation with degenerative changes on imaging?

A

someone experiencing neurological symptoms

78
Q

Bright white margins on x ray you’re looking at what?

A

subchondral sclerosis

79
Q

no clear margins btwn uncovertebral bodies telling you what?

A

uncovertebral bodies are sclerotic

80
Q

referred pain due to convergence or divergence in the dorsal or ventral gray?

A

Convergence in the dorsal gray matter!

81
Q

Referred pain along border of scapula likely to be from what?

A

disc

82
Q

referred pain in C5,6,7 likely to be from what?

A

interspinous ligaments

83
Q

what is referred pain generally described as?

A

dull and achy, poorly localized, deep

84
Q

upper cspine refers to what?

lower cspine refers to what?

A

upper: head, neck, shoulder

Lower: neck, shoulder, arm

85
Q

True or false: referred pain means nerve root compression

A

NOOOOO. no need to focus on “decompressing” NR

86
Q

You think you’re on C6 and C7, what can you do to check

A

Ask the pt to extend, C6 should disappear with moderate extension, C7 should disappear after excessive extension.

87
Q

Adams apple is what?

A

thyroid cartilage

88
Q

+ Flexion rotation test

A

> 10 degrees of lost motion side to side OR

<35 degrees

89
Q

What are the four classifications of neck pain

A

Neck pain w/

  • mobility deficits
  • movement coordination impairment
  • HA
  • radiating pain
