Spine Flashcards
What is the centering point for the lateral L5-S1 projection of the spine?
1.5 inches inferior to the iliac crest and 2 inches posterior to the ASIS
Where is the articular pillar located on a cervical vertebra?
Between the superior and inferior articular processes
The small section of bone found between the superior and inferior articular processes of the lumbar spine?
Pars interarticularis
Where does the CR enter for a lateral scrum and coccyx?
3-4 inches posterior to the ASIS
What attributes of the cervical spine set it apart from the rest of the spine?
Bifid spinous processes, Transverse foramen, and overlapping bodies
Articulations formed between superior and inferior articular processes are termed?
Zygapophaseal joint
Which position is/are recommended to demonstrate degree of cervical anterior/posterior movement?
Lateral in extension and flexion
When taking an AP axial projection of the cervical spine, the CR is directed:
15-20 degrees, cephalad
Which position of the cervical spine would demonstrate the downside left intervertebral foramina?
LAO
Abnormal or exaggerated convex curvature of the spine is termed?
Kyphosis
What is the name of the most anterior portion of the thoracic vertebra?
Body
If the lower lumbar spine is not supported so as to be parallel to the IR in the lateral position, the CR should?
5 degrees, caudad
Why should a scoliosis series be performed in the PA rather than AP projection?
To reduce dose to the breast, thyroid, and reproductive organs
A breathing technique is useful for which of the following positions/ projections?
Lateral thoracic spine
Involves the forward movement of one vertebra in relation to another.
Spondylolisthesis
