What is a Spondylolisthesis?
Spondylolisthesis is a condition in which a bone (vertebra) in the spine moves forward out of the proper position onto the bone below it.
- Congenital spondylolisthesis. A vertebra is defective from the time a person is born.
- Traumatic spondylolisthesis. An injury or trauma causes a vertebra to slip out of place.
- Post-surgical spondylolisthesis. A vertebra slips out of place after spinal surgery.
