Flashcards in Spinal Lecture 5 Deck (36):
1

what do the vertebrae do to accommodate forward flexion

the vertebrae rotate anteriorly (anterior sagittal rotation) and translate forward (anterior sagittal translation)

2

during forward flexion the __ of the upper vertebrae can not move and thefore the upper surface of the vertebral bodies lean ___

inferior articular facet of the upper vertebrae can not move and therfore the upper surface of the vertebral bodies lean downwards

3

what limits forward flexion

IVD, facet joint capsule, supraspinous ligament, interspinous ligament, ligamentum flavum and posterior longitudinal ligament

4

what spinal section has the greatest amount of forward flexion

L5/S1

5

during extension what movement do the vertebrae undergoe

posterior sagittal rotation and slight posterior translation

6

during extension __ move downward and impact against the ___ of the vertebrae below so that there is a bone-on-bone end feel

during extension INFERIOR articular processes move downward and impact against the LAMINA of the vertebrae below so that there is a bone-on-bone end feel

7

what limits extension of the spine

anterior fibres of the annulus fibrosus, anterior longitudinal ligament and a bit of the anterior part of the IVD

8

what spinal level does most extension occur at

l5-s1 but only 5-6 degrees

9

what happens to the body of the vertebrae and disc during side bending

body of the vertebrae tilts and the nucleus of the disc is displaced to the opposite side

10

with side bending where does the least/most amount of movement occur

least - at l5-s1 most - at l3/l4

11

what structures limit side bending of the spine

lumbrosacral fascia, capsular ligaments of facet joints, iliolumbar ligament and intertransverse ligament

12

T/F the spine was not built for rotation

TRUE

13

what is the max degrees of rotation at each spinal segment

3 degrees

14

which spinal segment has the least amount of rotation

L5

15

what structures limit spinal rotation

facet joints limit rotation first, then the disc, supraspinous ligament and interspinous ligament

16

what happens with the vertebrae, posterior facets and annulus of the disc during rotation

vertebrae tilt forward slightly, opening the posterior facets and stretching the posterior lateral annulus of the disc

17

what happens to the right facet during right rotation

with right rotation the right facet opens and the left facet closes and vice versa

18

if there is pain on the same side as rotation there is a ___ problem

if there is pain on the same side as rotation there is a CAPSULAR problem

19

if pain is on the opposite side as rotation there is an ___ problem

INTRA-ARTICULAR problem

23

What is the physiological movement with forward flexion and what is the accessory movement(s)?

Anterior sagittal rotation and anterior sagittal translation are Accessory movements – small involuntary movements

Physiologic movement is the forward flexion – large voluntary movements So with each physiological movement you get accessory movement as well

 

 

24

What things are restricted, pulled tight and compressed at end-range of motion for forward flexion?

 

Pulled tight: 

Supra, inter, ligamentum flavum and posterior longitudinal, zygoapopheaseal, posterior annulus fibres 

 

Relaxed:

Anterior longitudinal 

 

Compressed:

Anterior portion of IVD will become compressed pushing the nucleus pulposus posteriorly

 

25

Forward rotation of the pelvis is limited by the ____ ligament and ____.

 

Forward rotation of the pelvis is limited by the sacrotuberous ligament and hamstrings

 

26

Posterior pelvic rotation is limited by tension in the ____ ligaments and the ____.

 

Posterior pelvic rotation is limited by tension in the iliolumbar ligaments and the hip flexors

 

27

What limits extension? 

 

Anterior longitudinal ligament

Anterior fibres of annulus fibrosis

Zygoapopheseal joint – bony block

SP bony block

 

Psoas

Iliofemoral ligament

 

 

28

Whats relaxed in extension?

Posterior longitudinal

 

Supra, inter, flavum

 

29

What is compressed in extension?

Posterior aspect of disc – nucleus pulposus pushed anteriorly 

 

Facet – articular capsule

 

Capsule and fat pad can become compressed if not moved out of the way quick enough 

 

30

What things are restricted, pulled tight and compressed at end-range of motion for this movement? – SIDE BENDING ON RIGHT SIDE 

 

Intertransverse tight on left relax on right

Ligamentum flavum as well

 

Facet compressed on right side open on left – capsule would be stressed on left d

 

IVD disc compressed right side taught on left pushing nucleus pulposus left 

 

Iliolumbar taught on left side relaxed on right side 

 

Narrowing of intervertebral foramen on right side which will cause pressure on the nerves over time

 

Opening of space on left side but also more pull on nerve roots as they are being streatch

 

31

Orientation of facets in l-spine are facing largely lateral-medial which would limit _____.

 

 

Side bending

32

Ribs prevent side bending in t-spine despite the fact the orientation of the facets are ____.

anterior / posterior

33

You should see a ____ curve with side bending. Most people have restrictions which is causing _____ at specific areas not a steady curve. Implication is a lot of movement is going through a small area making it prone to ____.

 

You should see a gradual curve with side bending. Most people have restrictions which is causing hinging at specific areas not a steady curve. Implication is a lot of movement is going through a small area making it prone to injury

 

34

What happens to the facets and IVD during right rotation?

Left facets compress

Right facets open

 

 

IVD 50% annulus fibres are lax 50% are taught

 

35

Do not get much rotation in the lumbar spine because of .......

Do not get much rotation in the lumbar spine because of the orientation of the facets

 

36

What limits t-spine rotation?

 

The ribs except in the very low t-spine

 

In 9, 10, 11 and 12 the ribs do not attach to the transverse process 

 

So that where the majority of your rotation in your thoracic spine should occur is in the lower t-spine
