1
What is the location of spondylolysis that will be stressed in Spinal II?
a separation along the pars interarticularis (defect in the pars interarticularis or pars defect)
2
What is the incidence of spondylolysis in the general population?
a range of 2.6% to 10%
3
What is the geographic or ethnic bias for a higher incidence of spondylolysis?
the native Alaskan (Inuit) population
4
Lumbar spondylolysis has not been reported in what groups of individuals?
fetuses, newborns, rarely in children under five years old, patients who have never walked and in non-erect species
5
What does lumbar spondylolysis appear to be related to?
the uniquely human upright stance and erect posture
6
Lumbar spondylolysis is associated with what characteristics?
familial association, spina bifida occulta, racial/ethnic disparities, gender and locational bias, youthful incidence and activities requiring repetitive stress on the spine
7
What is the gender bias and locational bias associated with lumbar spondylolysis?
men at L5/S1; women at L4/L5
8
What age range is typically associated with lumbar spondylolysis?
10-20 years old
9
What activities are particularly stressful at the pars interarticularis of lumbar vertebrae?
gymnastics, dance, soccer
10
What fills the space in a lumbar spondylolysis
fibrocartilagenous material
11
What has been given to the material filling the space in a lumbar spondylolysis?
spondylolysis ligament
12
What types of neural function(s) have been associated with the spondylolysis ligament?
nociception, neuromodulation and autonomic function
13
What is the appearance of a lumbar vertebra upon oblique x-ray view?
a Scotty dog
14
What is the appearance of a spondylolysis in a lumbar vertebra upon oblique x-ray view?
a collared Scotty dog
15
In an oblique x-ray, spondylolysis below the superior articular process of a lumbar pars interarticularis is associated with what part of the Scotty dog?
the neck of the Scotty dog
16
What part of a lumbar vertebra forms the eye of a Scotty dog?
the pedicle
17
What part of a lumbar vertebra forms the ear of a Scotty dog?
the superior articular process
18
What part of a lumbar vertebra forms the nose of a Scotty dog?
the transverse process
19
What characteristics are associated with cervical spondylolysis?
rare, congenital, gender biased toward men, most common at C6 and linked to spondylolisthesis and spina bifida
20
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
21
What is the incidence of sacral spondylolysis in the general population?
it's rare
22
Is sacral spondylolysis the result of congenital conditions, acquired conditions or an age-related conditions?
it seems to be acquired
