The transverse process

12

What characteristics are associated with cervical spondylolysis?

Rare, congenital, gender biased toward men, most common at C6 and linked to spondylolisthesis and spina bifida

13

What characteristics are associated with sacral spondylolysis?

Rare in the general population
Within typical percent 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

14

What is the incidence of sacral spondylolysis in the general population?

It's rare

15

Is sacral spondylolysis the result of congenital conditions, acquired conditions or an age-related conditions?

It seems to be acquired

16

What is the ethnic, gender, and locational bias associated with sacral spondylolysis?

The native Alaskan (Inuit) male at the S1 level

17

Identify all names given to typical III spondylolisthesis?

Degenerative spondylolisthesis

What is the location bias of type I spondylolisthesis?

L5 or upper sacral segments

19

What additional conditions are linked to type 1 spondylolisthesis?

Spina bifida occulta and nerve root compression of the S1 nerve

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

Lytic spondylolisthesis or stress fracture induced spondylolisthesis

21

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

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

22

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

Teenagers or young adults

23

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

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

24

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

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

25

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

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