RADT316 Unit #5

QuestionAnswer
Normally, there are ________ lumbar vertebrae 5
Normally, there are ________ sacral vertebrae 5
Normally, there are ________ coccygeal vertebrae 3-5 (average is 4)
The sacrum and coccyx are called _______ vertebrae False vertebrae (they are fused together in adulthood)
The cervical, thoracic, and lumbar vertebrae are called _______ vertebrae True vertebrae (This is because they move and are the same throughout life as there is no fusing with age)
For an AP Axial Sacrum, the CR should be angled: 15 degrees cephalad
For an AP Axial Sacrum, the CR should be centered: 2 inches superior to pubic symphysis
For an AP Axial Coccyx, the CR should be angled: 10 degrees caudal
For an AP Axial Coccyx, the CR should be centered: 2 inches superior to pubic symphysis
For a Lateral Sacrum & Coccyx combined, the CR should be centered: 3-4 inches posterior to the ASIS
For a Lateral Sacrum only, the CR should be centered: 3.5 inches posterior to the ASIS
For a Lateral Coccyx only, the CR should be centered: 3-4 inches posterior and 2 inches distal from the ASIS
What is is an abnormally increased convexity in the thoracic curvature Kyphosis
What is an abnormal increased concavity in lumbar or cervical Lordosis
For the lumbar vertebrae, _________ form the lateral walls of the vertebral foramen Pedicles
For the lumbar vertebrae, _________ form the posterior lateral walls of vertebral foramen Lamina
For the lumbar vertebrae, _________ projects posteriorly and inferiorly, is the site for muscle attachments, and the lower tip lies at level of the disk space Spinous Process
For the lumbar vertebrae, to demonstrate the upper “z-joints” we should oblique the patient closer to: 50 degrees
For the lumbar vertebrae, to demonstrate the lower “z-joints” we should oblique the patient closer to: 30 degrees
For an AP Lumbar, the CR should be centered: Iliac crest
For an AP L5-S1, the CR should be angled: Male: CR 30 degrees cephalad Female: CR 35 degrees cephalad
For an AP L5-S1, the CR should be centered: Level of ASIS at the midline of body
For a Lateral Lumbar, the CR should be centered: Iliac crest
For a Lateral L5-S1 Spot, the CR should be angled: 5-8 degrees caudal
For a Lateral L5-S1 Spot, the CR should be centered: 1.5 inches inferior to the iliac crest and 2 inches posterior to ASIS
For an AP Oblique Lumbar (LPO/RPO), the patient should be oblique ______ degrees 45
For an AP Oblique Lumbar (LPO/RPO), the CR should be centered: 2 inches above iliac crest and 2 inches medial to the upside ASIS
The Zygapophyseal Joint ___________ (closest/furthest) to the IR is demonstrated when the patient is in the RPO and LPO Lumbar position Closest
However, the Zygapophyseal Joint __________ (closest/furthest) from the IR is demonstrated when the patient is in the RAO or LAO Lumbar position Furthest
For an PA Oblique Lumbar (LAO/RAO), the patient should be oblique ______ degrees 45
For an PA Oblique Lumbar (LAO/RAO), the CR should be centered: 1-2 inches above the iliac crest and 2 inches medial to upside ASIS
On a radiograph to determine that the correct amount of oblique was used on a lumbar, the pedicle should be seen: Halfway between the midpoint of the vertebral bodies and the lateral border of the vertebral body
On an Oblique Lumbar radiograph, if the z-joint is not seen well and the pedicle is anterior to the vertebral body, the patient is: Not rotated enough
On an Oblique Lumbar radiograph, if the pedicle is seen posterior to the vertebral body the patient is: Rotated too much
