Flashcards in Spondylolysis Deck (25):
1

What are some of the causes of spondylolysis?

- congenital
- acquired during development
- the result of aging
- the result of trauma

2

What are some locations of spondylolysis?

- 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

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

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

4

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

the anterior element from the posterior element

5

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

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

9

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

those species that walk erect; humans
