Q

What are some of the causes of spondylolysis?

A
  • congenital
  • acquired during development
  • the result of aging
  • the result of trauma
2
Q

What are some locations of spondylolysis?

A
  • between the right and left sides of the vertebral body
  • between the vertebral body and pedicle
  • between the parts of the pars interarticularis
  • between the right and left lamina
3
Q

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

A

a separation along the pars interarticularis (defect in the pars interarticularis or pars defect)

4
Q

What parts of a vertebra are separated as a result of a pars defect?

A

the anterior element from the posterior element

5
Q

What specific parts of a vertebra are separated as a result of a pars defect?

A

vertebral body, pedicle, and articular process (anterior elements) are separated from the other articular process, lamina, and spinous process (posterior elements)

9
Q

Lumbar spondylolysis has only been reported in what type of species?

A

those species that walk erect; humans

10
Q

Lumbar spondylolysis is associated with what characteristics?

A
  • familial association
