| A lateral lumbar spine image should clearly demonstrate the | intervertebral foramina, spinous processes, and disk spaces |
Which movement occurs at the thoracic spine?
The angles of the joints in the thoracic spine allow for motion in all planes: rotation, flexion/extension, and lateral flexion. However, the ribs block excessive lateral flexion from occurring. Sagittal plane flexion and extension is also available in the region of the thoracic spine.
Which Zygapophyseal joints are best demonstrated with an LPO position of the thoracic spine?

SJC Zerbe Procedures Semester 2 Unit 2
| Oh man…. | Yes! |
|---|---|
| Where should the arms be placed for a lateral projection of the thoracic spine? | at right angles to the long axis of the body This will aid in elevating the ribs to clear the intervertebral foramina |
Which of the following structures are best demonstrated on the lateral projection of the thoracic spine?

| Question | Answer |
|---|---|
| What are the lateral projections on a typical vertebra called? | Transverse processes |
| When viewed from the anatomic position, what type of natural curve is found in the thoracic spine? | Concave |

What is thoracic immobility?
What Happens if the Thoracic Spine is Immobile? If the thoracic spine is immobile, the lumbar spine will pick up the slack and compensate for the lack of movement in the thoracic spine. This can lead to low back pain and fatigue. On the opposite end of the thoracic spine, are the shoulders and neck.
What is the central ray angle for an AP thoracic spine?
When the shoulder is immobile and cannot be depressed sufficiently for the cervicothoracic region lateral projection (swimmer’s technique), the central ray is angled: 0 degrees. What is the central-ray angle for an AP thoracic spine? 20 degrees.
Which of the following methods is used to evaluate the thoracic and lumbar spine during scoliosis?
Scoliosis is usually confirmed through a physical examination, an x-ray, spinal radiograph, CT scan or MRI. The curve is measured by the Cobb Method and is diagnosed in terms of severity by the number of degrees.
