What are the routine exams of the forearm?
What is wrong if there is excessive separation between the radius and ulna on an AP forearm projection?
AP Forearm
Lateral Forearm
What are the routine exams of an elbow?
AP Elbow
Fully Extended
For the two AP Elbow partial flex projections, if the patient cannot extend elbow, and it remains at almost 90 degrees, what should you do?
AP Elbow
Partial Flex with humerus parallel
(patient cannot fully extend elbow - 2 projections)
AP Elbow
partial flex
forearm parallel
(2nd projection)
Which elbow projection/position best demonstrates the radial neck-head with only slight superimposition?
Which elbow projection/position best demonstrates the coronoid process?
Which fat pad of the elbow will only appear on x-ray if there's a joint pathologic process?
Why does the elbow need to be in 90 degree flexion to determine whether the posterior fat pad is visible or not?
for an AP forearm, the distal humeral epicondyles are _____ to the IR
For the lateral forearm, the distal humeral epicondyles are _____, or _____ over the IR
Epicondyles must be _____ to the IR for an AP fully extended elbow projection.
AP Oblique
Lateral (External) Rotation
AP Oblique
Medial (Internal) Rotation
AP Lateral Elbow
What are some special projections of the elbow?
Acute Flexion
(1st Projection)
CR perpendicular to Humerus
Acute Flexion
(2nd Projection)
CR Perpendicular to proximal forearm
Why would you perform an acute flexion projection?
Trauma Axial Lateral
*Coyle Method*
for radial head
Trauma Axial Lateral
*Coyle Method*
for coronoid process
Why would you perform the Coyle Method?
COYLE METHOD
alternative view
supine, CR angled 45 degrees to the shoulder, elbow flexed 90 degrees
COYLE METHOD
alternative view
supine, CR angled 45 degrees away from the shoulder, elbow flexed 80 degrees
What is the only difference among the four radial head lateral projections of the elbow?
Why would you perform any of the 4, or all 4 of the radial head lateral views?
Some sites use this projection as part of their routine elbow series. Which one is it?
According to the textbook, the CR is perpendicular to the IR and humerus, directed to a point midway between epicondyles for ______ when the elbow is in acute flexion.
How many exposures are required for the AP Acute Flexion series?
How much is the elbow flexed for a Trauma Axial Lateral Projection (Coyle Method) to demonstrate the coronoid process?
Which oblique elbow projection best demonstrates the coronoid process?
Which oblique elbow projection best demonstrates the radial head and neck?
Which elbow projection best demonstrates pathologic issues such as osteomyelitis and arthritis?
According to the textbook, the CR perpendicular to the forearm (angling CR as needed), directed to a point 2 in proximal or superior to the olecranon process, with the elbow in acute flexion, indicates which projection/position?
Which trauma axial elbow projection has the elbow flexed 80 degrees?
And what specific anatomy is this projection demonstrating?
Which way is the tube angled for this projection?
Which Trauma Axial Lateral projection has the elbow in 90 degree flexion with the hand pronated?
What specific anatomy does this projection demonstrate?
Which way is the tube angled for this?
Which projection/position best demonstrates occult fractures or the radial head or neck?
How is the CR angled for the radial head lateral view?
What is in profile for a lateral oblique elbow?
What anatomy is in profile for a medial oblique elbow?
For the axial radial head view, how is the hand positioned?
