| Inflammatory condition that usually begins in the sacroiliac joint and progresses up the vertebral column. | Ankylosing Spondylitis |
| Common in males in their 30's and no cause is known. | Ankylosing Spondylitis |
| Due to trauma, osteoporosis, or metastatic disease. Superior and inferior surfaces of the vertebra body are driven together, producing a wedge-shaped vertebra. | Compression Fracture |
| A type of fracture rarly causes a neurologic defect. | Compression Fracture |
| The soft inner part of the intervertebral disk protrudes through the fibrous outer layer, pressing on the spinal cord and nerves. | Herniated Nucleus Pulposus |
| What is another name for Herniated Nucleus Pulposus? | Herniated Lumbar Disc |
| Where does Herniated Nucleus Pulposus frequently occur at? | L4 to L5 |

| Lateral curvature of the vertebral column that usually occurs with some rotation of the vertebra. | Scoliosis |
| Congenital condition in which the posterior aspects of the vertebrae fail to develop, thus exposing [part pf the spinal cord. | Spina Bifida |
| This condition varies greatly in severity and occurs most often at L5 | Spina Bifida |
| Involves forward movement of one vertebra in relation to another. | Spondylolisthesis |
| Commonly due to a developmental defect in the pars interarticularis. | Spondylolisthesis |
| Most common at L5-S1 but also occurs at L4-L5. | Spondylolisthesis |
| Severe cases of this will require a spinal fusion. | Spondylolisthesis |
