What is the earliest indicator of the position of the adult intervertebral disc?

the intrasclerotomal fissure or fissure of von Ebner

2

What vertebral levels will the anterior longitudinal ligament attach to?

those between occiput and S3 inclusive are traditionally indicated

3

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

Forestier's Disease

4

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

Diffuse Idiopathic Skeletal Hyperostosis or DISH

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

the cervical spine with an 80% incidence

7

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

8

What is the acronym for ossification of the posterior longitudinal ligament?

OPLL

9

At one time ossification of the posterior longitudinal ligament was an example of what condition?

Diffuse Idiopathic Skeletal Hyperostosis or DISH

10

In which region of the spine will the ligamentum flavum be paired?

the lumbar spine

11

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

it is a yellow elastic ligament

12

What is the function of the ligamentum flavum?

it breaks or limits flexion of the vertebral column

13

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

Where is ossification of the ligamentum flavum most commonly identified?

the thoracic spine or thoracolumbar transition zone

15

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

the cervical and lumbar regions

16

If the zygapophyseal capsular ligament is not significantly involved in restricting motion what is its' function?

it is probably involved in proprioceptive feedback to the muscles stabilizing the vertebral couple during movement
