Flashcards in Lumbar - Lecture Deck (47):
1

It is important to inspect for what type of skin markings when dealing with the lumbar spine?

Lipomatas
Hairy Patches
Café-Au-Lait spots
Birth Marks

What is the name of the genetic autosomal dominant trait disorder that produces pigmented spots, and pedunculated soft tissue nodules clustered along nerve sheaths?

Neurofibromatosis

3

Name some bone changes that may result in skeletal deformities that are associated with Neurofibromatosis

Vertebral body scalloping
Fibrous Dysplasia
Tibial Pseudoarthrosis
Sphenoid bone deformity

4

What is a gibbous deformity?

A sharp kyphosis in the lower thoracic, affecting the normal lordosis of the lumbar spine

5

T or F

The top of the iliac crest is around the level of L3-L4

False

L4/L5

6

If there is a pars interarticularis defect in the lumbar spine we typically refer to it as what?

Spondyloslisthesis Spondylolysis

7

T or F

A spondylolisthesis is ONLY a unilateral defect in the pars

False

Can be bilateral as well

8

What measurement technique is used to grade a Spondy?

Meyerding's Scale

9

The articulations between two consecutive lumbar vertebrae form how many joints?

3
1 between the 2 bodies and the IVD
The other 2 are formed by the articulation of the Superior articular process of one vertebra and the inferior of the vertebra above.

10

The umbilicus lies at what lumbar disc levels

L3-L4

11

What is the primary function of the zjoint in the lumbar spine

To protect the motion segment from anterior shear forces, excessive rotation, and flexion

12

T or F

The ALL becomes thicker as it ascends

False

13

What ligament connects two consecutive laminae?

Ligamentum Flavum

14

T or F
Interspinous ligaments connect the tips of two adjacent spinous process.

False

Supraspinous ligaments
- the question was describing the interspinous ligament

15

What ligament functions to restrain flexion, extension, and axial rotation as well as side bending of L5 on S1

Iliolumbar Ligament

16

T or F

The Quadratus Lumborum is an important muscle for the lumbar segmental stability through its ability to provide segmental stiffness and control motion

False

This is the function of the Lumbar Multifidus

17

Describe the importance of the Thoracolumbar fascia.

Assists in the transmission of extension forces during lifting activities and stabilizes the spine against anterior shear and flexion moments.

18

What muscle takes origin from the anterior portion of T12-L5 vbodies & discs? What is its main function?

Psoas
The main hip flexor

19

T or F

in the lumbar spine a disc pathology affects the nerve root below

True

20

T or F

A disc is named after the vertebrae below

False

Above

21

T or F

Prolapse aka Protrusion

False

aka Bulge

22

Describe a disc protrusion

A little piece of the nucleus pulposus protrudes into the annular fibres

23

T or F

With a bulging disc the nucleus pops out of the annular fibres but there has not yet been torn fibres

True

24

What is an aka for Extrusion of a disc?

Herniation

25

Describe an extruded disc

Annular fibres are torn and the nucleus bursts into the PLL and the PLL is torn. Patient often describes a shredding noise.

26

When multiple pieces of the nucleus are in the spinal canal this is called?

Sequestered Disc

27

L4 reflex = ?

Patellar Reflex

28

Foot dorsiflexion and inversion is testing what muscle and what nerve root?

L4
Tibialis Anterior - deep peroneal nerve

29

T or F

L4 dermatome is the lateral leg, behind the lateral malleoli and along the 2-4th toes

False

Medial leg, behind the medial malleoli and along the medial side of the food and great toe.

30

T or F

L5 muscle testing is evaluating primarily foot, big toe, and toes 2,3,4 plantar flexion

False

Dorsiflexion

31

What nerve root is evaluation Hip and Pelvis abduction

L5

32

Hip and pelvis abduction muscle testing tests what muscles?

Gluteus medius and minimus - superior gluteal nerve

33

Foot plantar flexion muscle test is stressing what muscles?

Gastrocnemius and Soleus innervated by Tibial Nerve

34

T or F

Foot plantar flexion and eversion is testing the peroneus longs and braves innervated by the deep peroneal nerve

False

Superficial peroneal nerve

35

What is the reflex for S1

Achilles

36

What nerves innervate the outer half of the IVD

Sinuvertebral nerve and the grey rami communicans

37

What part of the IVD receives only sympathetic innervation

The lateral aspect

38

The Z joints are innervated by what nerve?

The medial branches of the dorsal rami

39

Motion in the lumbar spine can occur in what cardinal planes

Sagittal - flexion and extension
Coronal - Side bending
Transverse - rotation

40

T or F
Most of the flexion and extension of the lumbar spine occurs in the upper segmental levels

FALSE bitches
Lower segmental levels

41

Where does most of the side bending occur?

Mid-lumbar region

42

Where does most of the rotation occur?

It is coupled with side bending however most of the rotation occurs at the lumbosacral junction

43

Does flexion or extension of the lumbar spine cause a minimal reversal of the lordosis

Flexion

44

What motion of the lumbar spine is associated with an anterior roll and an anterior glide of the vertebral body

Flexion

45

Axial rotation of the lumbar spine amounts to approx how many degrees?

13 to both sides

L5-S1
5 degrees

47

Name some of the Acute Phase Goals mentioned in the powerpoint

Decrease pn, inflammation and muscle spasm
Promote healing of tissues
Increase pn free ROM
Regain soft tissue extensibility
Regian neuromuscular control
Allow progression to the functional stage
