Scapula

Question 1

CR: Perpendicular to the mid scapular area at a point
approximately 2 inches inferior to the coracoid process.
POSITION:
- Abduct the arm to a right angle with the
body to draw the
scapula
laterally. Then flex the
elbow, and support the
hand in a comfortable
position.
-Position the top of the
IR 2 inches above the top of the shoulder.
STRUCTURE SHOWN: An AP projection of the
scapula is demonstrated.

Answer 1

AP PROJECTION

Question 2

CR: Perpendicular to the midmedial border of the protruding scapula.
POSITION:
- Adjust the patient in an RAO or LAO position,
with the affected
scapula centered to the
grid. The average
patient require a 45 to
60 degree rotation.
- Flex the elbow and
place the back of the
hand on the posterior
thorax.
STRUCTURE SHOWN: A lateral image of the
scapula is demonstrated by this projection.

Position 2
POSITION:
- Have patient reach
across front of chest
and grasp opposite
shoulder.

Answer 2

LATERAL PROJECTION
(RAO or LAO body position)

Question 3

CR: Perpendicular to the IR, between the chest wall and the mid area of the protruding scapula.
POSITION:
- With the patient in the
lateral position, upright
or recumbent, center
the scapula to the
midline of the grid
device.
STRUCTURE SHOWN: An oblique image of the scapula
is shown. The degree of obliquity depends on the
position of the arm.

Answer 3

PA OBLIQUE PROJECTION LORENZ AND
LILIENFELD METHODS (RAO or LAO position)

Question 4

• Adjust the arm of the affected side at a
  right angle to the long axis of the body, flex
  the elbow, and rest the hand against the
  patient’s head.
• Rotate the body slightly forward.

Answer 4

LORENZ METHOD

Question 5

• Extend the arm of the affected side obliquely upward, and have the patient rest
  the hand on his or her head.
• Rotate the body slightly forward

Answer 5

LILIENFELD METHOD

Question 6

CR: Directed to enter the coracoid process at an angle
of 15 to 45 degrees cephalad.
POSITION:
- Place the patient in the supine position with the arms
along the sides of the body.
- Center the affected coracoid process to the midline of
the grid.
- Abduct the arm of the affected side slightly, and
supinate the hand.
STRUCTURE SHOWN: A slightly elongated
inferosuperior image of the coracoid process is illustrated.

Answer 6

Coracoid Process AP AXIAL PROJECTION

Question 7

CR: Directed through the posterosuperior region of the
shoulder at an angle of 45 degrees caudad.
POSITION:
- Center the shoulder to the midline of the grid.
-Turn the head away from the shoulder being examined.
STRUCTURE SHOWN: The spine of the scapula is shown
in profile and is free of bony superimposition, except for
the lateral end of the clavicle
