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 the descriptive term for a combination of Osteoblastic and Osteolytic? Moth - eaten
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
