What are some of the causes of spondylolysis?

congenital, acquare during development, the result of aging, or the result of trauma

6

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

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

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

the anterior element from the posterior element

8

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

the vertebral body, pedicle, and articular process are separated from the other articular process, lamina, and spinous process.
