Disc degeneration and prolapse • Rupture • Prolapse • Protrusion • Herniation
Intervertebral disk • Nucleus pulposus [protein polysaccharide, collagen fibres, chondroid cells, 80% water] • Annulus fibrosis[ concentric layers of fibrus tissue]
Spinal stenosis • Congenital [achondroplasia,hypochondroplasia] • Post degenerative • Post spondylolisthetic • Iatrogenic • Miscellaneous [Paget’s,tumors,TB]
Infections • Tuberculosis • Pyogenic spondylitis • Discitis
Spondylolysis-Spondylolisthesis • Dysplastic [some of the facets are displastic] • Lytic [stress fracture] • Degenerative • Post traumatic • Pathological • Iatrogenic
