Spondylolysis is the defect between joints of vertebrae and characterized by pain. The main cause of Spondylolysis is stress or constant over-stretching of the spine. This defect can lead to stress fractures (breaks) in the vertebrae that can weaken the bones so much that one slips out of place, a condition called spondylolisthesis.
