18
Q

What is the location bias of type I spondylolisthesis?

A

L5 or upper sacral segments

19
Q

What additional conditions are linked to type 1 spondylolisthesis?

A

Spina bifida occulta and nerve root compression of the S1 nerve

20
Q

Which subtype of type II spondylolisthesis is stressed in Spinal II?

A

Lytic spondylolisthesis or stress fracture induced spondylolisthesis

21
Q

What is the cause most frequently given for type II spondylolisthesis?

A

Micro fractures as the result of repetitive stress during hyper Flexion and rotation

22
Q

What is the age group typically associated with type II spondylolisthesis?

A

Teenagers or young adults

23
Q

Lumbar spondylolysis has not been reported in what group of individuals?

A

Fetuses, newborn, rarely in children under five years old, patients who have never walked and in non-erect species

24
Q

What gender bias, locational bias, and spinal canal dimensions are associated with type II spondylolisthesis?

A

Isthmus spondylolisthesis is common in men, located at the L5/S1 level and demonstrates an increase in Sagittal diameter of the spinal canal

25
Q

What is the gender bias, locational bias, and spinal canal dimension changes often associated with type III spondylolisthesis?

A

Degenerative spondylolisthesis is more common in women, particularly at L4/L5, and demonstrates no change in Sagittal diameter of the spinal canal

26
Q

What causes type IV spondylolisthesis?

A

Fracture of the neural arch components

27
Q

What are the cause(s) associated with type V spondylolisthesis?

A

Bone diseases such as Paget disease or osteogenesis imperfecta

28
Q

What are medullary feeder arteries?

A

Enlarged radicular arteries which join the arterial vasa corona to provide blood for the spinal cord

29
Q

What is the name of the largest medullary feeder artery?

A

The artery of Adamkiewicz or the arteria radicalis manga anterior

30
Q

What are the characteristics of the Artery of Adamkiewicz?

A

It is the left side, anterior medullary feeder artery, located in the T9/T10 intervertebral foramen, and the primary vascular supply to the lumbar enlargement

31
Q

What venous plexus lies next to the posterior longitudinal ligament?

A

The anterior internal vertebral venous plexus

32
Q

What will the intervertebral veins drain into?

A

The external vertebral venous plexus or Batson’s plexus

33
Q

What is a unique histological feature of the veins of the vertebral column?

A

They appear to lack valves

34
Q

What size lymphatic vessels lie in the intervertebral foramen?

A

Medium sized lymphatics

35
Q

What type(s) of connective tissue will be present in the intervertebral foramen?

A

Adipose tissue and loose areolar connective tissue

36
Q

What parts of the cervical vertebra will modify the intervertebral foramen?

A

The lateral groove and uncinate process

37
Q

What happens to cervical nerve roots between their origin from the spinal cord and exit from the intervertebral foramen?

A

They descend along the spinal cord

38
Q

What is the relationship between aging and cervical spine nerve root characteristics?

A

The length of the nerve root increases as it descends from its apparent origin on the spinal cord, but the cross-sectional area of the nerve root decreases

39
Q

What is the relationship between aging and cervical spine intervertebral foramen size?

A

The cross-sectional area diminishes after age 50

40
Q

What are the specific attachment sites for a cervical spinal nerve?

A

The sulcus for the ventral primary Ramus on the costotransverse bar and the vertebral artery

41
Q

What contributes to the anterior boundary of the thoracic intervertebral foramen?

A

The costocentral joint
