Spondylolysis and Spondylolisthesis Information

Spondylolysis and Spondylolisthesis


The vertebral column is made up of thirty-three individual vertebra — they are grouped into seven cervical (neck), twelve thoracic (upper back), five lumbar (low back), and five sacral (fused to form part of the pelvis) and four coccygeal bones (also fused, form the tailbone). The column is flexible to aid mobility. It provides bony protection to the delicate spinal cord.

A degenerative defect in the vertebral arch is called spondylolysis. It may result in a stress fracture. If the bony parts separate, one vertebra will slip forwards in relation to the one below it, this is known as spondylolisthesis. This is most common at the junction between the lumbar and sacral spines (L5/S1).
