1
Q

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

A

Forestier’s Disease

2
Q

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

A

Diffuse Idiopathic Skeletal Hyperostosis or DISH

3
Q

What is hyperostosis?

A

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

4
Q

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

A

the cervical spine with and 80% incidence

5
Q

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

A

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

6
Q

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

A

it is a yellow elastic ligament

7
Q

What fibers are most ligaments made of?

A

collagen type I fibers which are whitish in appearance

8
Q

What is the function of the ligamenum flavum?

A

It brakes or limits flexion of the vertebral column

9
Q

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

A

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

10
Q

Were is ossification of the ligamentum flavum most commonly identified?

A

the thoracic spine or thoracolumbar transition zone

11
Q

What is the relationship between the capsular ligament and mobility?

A

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

12
Q

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

A

the cervical and lumbar regions

13
Q

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

A

they are poorly developed as ligaments although collagen fibers are present

14
Q

What is the status of the cervical interspinous ligament?

A

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

15
Q

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

A

it is more likely a proprioceptive trasnducer for the spinal reflex

16
Q

What are the layers of liamentum nuchae?

A

a superficial and deep layer are identified

17
Q

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

A

the funicular layer or part

18
Q

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

A

the lamellar layer or part

19
Q

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

A

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

20
Q

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

A

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

21
Q

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

A

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

22
Q

Where is the supraspinous ligament said to be best developed?

A

in the lumbar spine

23
Q

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

A

it is a proprioceptive transducer for the spinal reflex

24
Q

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

A

in the lumbar spine

25
Q

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

A

the ventral slip

26
Q

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

A

the dorsal slip
