Lumbar Spine

These are common radiograph views of the lumbar spine. Note that the bony prominences of the spine are "flattened" (superimposed) in the AP projection. The junction between the thoracic spine and lumbar spine is seen by identifying the 12th ribs.

Identify the following:

1. T12 ribs

2. vertebral body L1

3. transverse process L2

4. spinous process L3

5. pedicle L3

6. inferior articular facet L2

7. superior articular facet L3

8. intervertebral disc L3-4

9. intervertebral foramen L3-4
