Answer 1

Psoas Muscles

Question 2

Answer 2

1 1/2 inches superior to the illiac crest at MSP

Question 3

When is rotation present on this projection?

Answer 3

When the spinous processes are NOT in the middle of the vertebral body

Question 4

What side does the spinous processes rotate and that demonstrates the least distance from the spinous processes to the pedicles?

Answer 4

The side of the patient that is positioned farther from the IR

Question 5

When there is rotation, Where do the sacrum and coccyx rotate?

Answer 5

Toward the side of the pelvic inlet that is positioned farther from the IR

Question 6

What type of curvature does the lumbar spine have in the supine position when the patient is in a supine position with the legs extended?

Answer 6

Exaggerated Lordotic Curvature

Question 7

When dealing with lordotic curvatures, how is the curvature when the disk spaces of T12-L3 are open and the sacrum demonstrates less foreshortening and it is positioned close to the public symphysis?

Answer 7

The lordotic curvature was adequately reduced

Question 8

When dealing with lordotic curvatures, how is the curvature when the disk spaces of T12-L3 are closed, and the sacrum is foreshortened and is positioned farther from the public symphysis?

Answer 8

The lordotic curvature was NOT adequately reduced
