Flashcards in Ligaments of Vertebral Column Deck (26):
1

What was ossification of the anterior longitudinal ligament in the lumbar region identified as?

Forestier's Disease

2

What is ossification of the anterior longitudinal ligament in the lumbar region now identified as?

Diffuse Idiopathic Skeletal Hyperostosis or DISH

3

What is hyperostosis?

a greater than necessary ossification of the bone at a site of ligament attachment

4

Where is ossification of the posterior longitudinal ligament most commonly identified?

the cervical spine with and 80% incidence

5

What is the gender, age, and ethnic bias associated with ossification of the posterior longitudinal ligament?

it is greater in males over 50 and has a higher incidence in the Japanese

6

What is the name given to the ligamentum flavum based on appearance and histology?

it is a yellow elastic ligament

7

What fibers are most ligaments made of?

collagen type I fibers which are whitish in appearance

8

What is the function of the ligamenum flavum?

It brakes or limits flexion of the vertebral column

9

What is now thought to be a major function of the ligamentum flavum?

it is an early prime factor in extension of the vertebral column

10

Were is ossification of the ligamentum flavum most commonly identified?

the thoracic spine or thoracolumbar transition zone

11

What is the relationship between the capsular ligament and mobility?

the more lax/loose the capsular ligament is, the greater the motion of the joint

12

What regions of the vertebral column demostrate the greatest laxity of capsular ligaments?

the cervical and lumbar regions

13

What is the status of the human interspinous ligament compared with other common ligaments?

they are poorly developed as ligaments although collagen fibers are present

14

What is the status of the cervical interspinous ligament?

it is lacking, poorly developed, or simply considered the deep anterior part of the ligamentum nuchae

15

What is now thought to be a major function of the interspinous ligament?

it is more likely a proprioceptive trasnducer for the spinal reflex

16

What are the layers of liamentum nuchae?

a superficial and deep layer are identified

17

What is the name given to the superficial layer of the ligamentum nuchae?

the funicular layer or part

18

What is the name given to the deep layer of the ligamentum nuchae?

the lamellar layer or part

19

What are the attachment sites for the superficial layer of the ligamentum nuchae?

the external occipital protuberance, external occipital crest, and spinous tubercle of C7

20

What is the histological make-up of the human ligamentum nuchae?

it is a yellow elsatic ligament, but has more collagen fibers than in quadrupeds

21

What is the termination level inferiorly for the supraspinous ligament according to current literature?

primalrily at L4(73%); between L4 and L5 (5%)

22

Where is the supraspinous ligament said to be best developed?

in the lumbar spine

23

What is now thought to be the major function of the supraspinous ligament?

it is a proprioceptive transducer for the spinal reflex

24

Where in the vertebral column is the intertransverse ligament best developed?

in the lumbar spine

25

What part of the intertransverse ligament in the lumbar spine covers the intervertebral foramen?

the ventral slip

26

What part of the intertransverse ligament in the lumbar spine divides the body wall into an anterior muscular compartment and a posterior muscular compartment?

the dorsal slip
