Chapter 9 Lumbar, Sacrum, and Coccyx Flashcards
The Primary curve is also called
Kyphotic curve
The kyphotic curve includes
Thoracic spine
Pelvic curve: Sacrum/coccyx
The secondary or compensatory curve is also known as
Lordotic Curve
The lordotic curve consists of
cervical spine
lumbar spine
Spinal Nerves and blood vessels exit through the
Intervertebral Foramen
What are the routine images done for a Lumbar Spine?
AP
Both Obliques
Lateral
Spot
How can you locate L1 on an image
L1 has no rib attachment
For the Lumbosacral spine you will center at
level of iliac crest
for the lumbar spine only, you will center
1.5in above the iliac crest
Obliques are used to see the _______ joints.
Zygapophyseal
RPO will demonstrate the _______ Zygapophyseal joints.
right
For RPO, the CR is
1.5in above crest, and 2 in medial to ASIS on up side
The ear of the Scottie dog is the
Superior articular process
The eye on the scottie dog is the
pedicle
The front leg of the scottie dog is the
Inferior articular process
How many vertebra in the Sacrum?
5
Articulations between the articular process of the vertebral arches are called
Zygapophyseal
If an intervertebral disk slips and it protrudes into the vertebral column it is called a
Herniated disk
Bending the legs reduces
Lordotic Curve
where do we center for an AP lumbar?
1.5in above iliac crest
which joint is displayed on AP obliques ?
joint closes to IR
which projection of the Lumbar spine shows the scottie dogs?
AP and PA obliques
What is the angle for AP sacrum?
15 degrees cephalic
what is the angle for AP coccyx?
10 degrees caudal
For the lateral Scarum, the CR is at
level of ASIS, and 3in posterior
Where is the CR on a lateral coccyx
3in. posterior to ASIS and 2in Inferior
What is done to decrease radiation exposure to the patient?
Collimation
Breast shields
PA projection
Which SI joint is demonstrated in RPO?
Left
Which SI joint is demonstrated in LPO?
Right SI joint
The nose of the Scottie dog is the
Transverse Process
What is located behind the ear on the scottie dog?
Zygapophyseal
An AP axial lumbosacral junction and SI joints have a tube angulation of
30-35 degrees cephalic
For AP obliques of the SI joints, the patient is angled
25-30 degrees
for AP obliques, the CR enters
1in medial to the up ASIS
What positions are performed for Sacroiliac joints?
AP axial
both obliques
the Scoliosis series should include
all of T-spine and L-spine and 1in of iliac crest
A spot view should demonstrate
an open lumbosacral joint
what tube angle is used on a female when doing the spot L5-S1?
8 DEGREES caudal
