a vertebral separation or vertebral cleavage

9

What is the definition of spondylolisthesis?

a vertebral slippage

10

What is the location of spondylolysis that will be stressed in spinal II?

a separation along the parts interarticularis (defect in the pars interarticularis or pars defect?

11

What is the incidence of spondylolysis in the general population?

2.6% - 10%

12

What is the geographic or ethnic bias for a high incidence of spondylolysis?

native Alaskan (Inuit) population

13

What does the lumbar spondylolysis appear to be related to?

the uniquely human upright stance/erect posture

14

Lumbar spondylolysis is associated with what characteristics?

familial association, spina bifida occulata, racial/ethnic disparities, gender and locational bias, youthful incidence and activities requiring the repetitive stress on the spine

15

What is the age range typically associated the lumbar spondylolysis?

10-20 year olds

16

What activities are particularly stressful at the pars interarticularis of lumbar vertebrae?

gymnastics, dance, soccer

17

What fills the space in lumbar spondylolysis?

fibrocartilagenous material

18

What nme has been given to the material filling the space in a lumbar spondylolysis?

spondylolysis ligament

19

What types of neural function(s) have been associated with the spondylolysis ligament?

nociception, neuromodulation and autonomic function

What is the appearance of the lumbar vertebra upon oblique x-ray view?

a Scotty dog

21

What is the appearance of a spondylolysis in a lumbar vertebra upon oblique x-ray?

a collard Scotty dog

22

In an oblique x-ray, spondylolysis below the superior articular process of lumbar pars interarticularis is associated with what part of the Scotty dog?

the neck of the Scotty dog

23

What part of the lumbar vertebra forms the eye of a Scotty dog?

the pedicle

24

What part of a lumbar vertebra forms the ear of the Scotty dog?

superior articular process

What part of the lumbar vertebra forms the nose of the Scotty dog?

transverse process

26

What characteristics are associated with cervical spondylolysis?

rare, congenital, gender bias towards men, most common at C6 and linked to spondylolisthesis and spina bifida

27

What characteristics are associated with sacral spondylolysis?

rare in the general population, within typical percents in the native Alaskan (Inuit) population,
seems to be acquired, gender biased toward men,
most common at S1 and linked to activities such as kayaking and harpooning

31

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

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

32

What gender bias, locational bias, and spinal canal dimension are associated with type III spondylolisthesis?

degenerative spondylolisthesis is more common in women,
