a vertebral slippage
What is the current limited definition of spondylosis?
a vertebral condition that is acquired or age-related
What are some of the causes of spondylolysis?
congenital, acquare during development, the result of aging, or the result of trauma
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
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.
What are the anterior elements of the vertebra?
the other articular process, lamina, and spinous process
