[MUSIC PLAYING] In this view, we will be
demonstrating the AP elbow. The AP elbow should be performed
with the patient seated at the end of the
radiographic table, with the image receptor
placed tabletop, with a 40 inch source-to-image
distance, and no tube angulation. So I have the patient sit
at the end of the table at a right angle to the table. We have a shield
placed on her lap. She's going to
outstretch her arm, and her arm is going
to be supinated with her palm of her hand up. We're going to center right in
the middle of the elbow joint. So I'm going to make it
more comfortable for her. We're going to put the
long axis of her arm down the long axis of
the IR, the central ray right at the elbow joint. We want to extend our
collimation to about an inch on either side. We want about 2 to 2 and
1/2 inches into the humerus and down into the
radius and the ulna. We want to place our marker. And here you will see the
distal humerus, the elbow joint, and the proximal
radius, and ulna. The patient will hold very still
and then the exposure is taken. A diagnostic AP
elbow radiograph must be free of motion and rotation. Demonstrated anatomy to
include the radial head, neck and tuberosity slightly
superimposed over the proximal ulna with proper
visualization of soft tissue and bony detail. In this view, we will
demonstrate the medial oblique elbow. The medial oblique elbow should
be performed with the patient seated at the end of
the radiographic table, with the image receptor
placed tabletop with a 40 inch source-to-image distance,
and no tube angulation. For the medial
oblique, we're going to let her arm just
relax towards the midline of the body, and it's
at a 45 degree angle. We're still centered
at the elbow joint. Our collimation
remains the same. And on this particular view
we will see the coronoid. A diagnostic medial
oblique elbow radiograph must be free of motion and
a 45 degree medial rotation. Demonstrated
anatomy to include the coronoid process in profile
and the radial head and neck superimposing the ulna,
with proper visualization of soft tissue and bony detail. In this view, we
will be demonstrating the lateral oblique elbow. The lateral oblique
elbow should be performed with
the patient seated at the end of the
radiographic table, with the image receptor
placed tabletop, with a 40 inch source-to-image
distance, and no tube angulation. The lateral oblique, we're
going to have the patient rolled to the lateral side. It is an awkward
position to hold. We're going to still
center at the elbow joint. We're rolling away
from the midline, So we're rolling to
the lateral side. We're going to see the radial
head and the radial neck, and we'll definitely
see the distal humerus and the proximal radius
and ulna, and the patient holds very still. A diagnostic lateral
oblique elbow radiograph must be free of motion and have
a 45 degree medial rotation. Demonstrated anatomy
to include the radial head and neck will be
projected free of the ulna with proper visualization of
soft tissue and bony detail. In this view, we
will be demonstrating the lateral elbow. The lateral elbow
should be performed with the patient seated at the
end of the radiographic table, with the image receptor
place tabletop, with a 40 inch source-to-image
distance, and no tube angulation. So our patient is now
90 degrees or her palm is exposed like this, and
we are going to turn the IR. It is essential that
her arm is down, touching the table top
so her arm or elbow is in truly a lateral position. So the olecranon
is in profile here. We're still centering on
top of the elbow joint. We're going to extend that
collimation to about 2 and 1/2 inches into
the radius and ulna, and the exposure is made. A diagnostic lateral
elbow radiograph must be free of
motion and rotation with the elbow
flexed 90 degrees. Demonstrate the
anatomy to include the superimposed
humeral epicondyles, with proper visualization of
soft tissue and bony detail. [MUSIC PLAYING]
