Elbow Positioning Flashcards
Where do you center on an AP elbow? And what is the hand position?
Mid elbow joint
Hand supinated
On an AP elbow, when the arm cannot be fully extended, how can you tell if the humerus or forearm was parallel to the IR?
Humerus parallel- radial head and ulna more superimposed
Forearm parallel- radial head and ulna open
What is the hand position for an AP oblique elbow with medial rotation?
Pronated
What is the hand position for an AP oblique elbow with lateral rotation?
From supine position the hand is rotated with pinky side up to a 45 degree angle
Which elbow projection best demonstrates the coronoid process?
AP oblique elbow with medial rotation
What is the hand position for a lateral elbow?
Thumb up pinky down
What is the method name for an acute flexion elbow projection?
Jones Method
Where is the CR for the jones method when looking at the distal humerus?
Perpendicular to the IR midway between the epiondyles
What is the CR for the Jones method when looking at the forearm?
Angled to be perpendicular to the forearm and two inches superior to the olecranon process
What is the method name for the trauma axial lateral elbow projections?
Coyle method
What is the part position and CR for a Coyle method elbow when looking at the radial head?
Arm flexed 90 degrees CR angled 45 degrees toward shoulder
What is the part position and CR for the Coyle method when looking at the coronoid process?
Arm flexed 80 degrees and CR 45 degrees toward forearm
What are the 4 hand positions for the radial head lateral projections?
- Hand supinated with maximum external rotation
- Hand lateral
- Hand pronated
- Hand pronated with maximum internal rotation
Where is the radial tuberosity when the hand is externally rotated for a radial head projection?
Superior, above radius
Where is the radial tuberosity when the hand is lateral for a radial head projection?
Toward middle of the radius
Where is the radial tuberosity when the hand is pronated for a radial head projection?
Toward bottom of radius
Where is the radial tuberosity when the hand is internally rotated for a radial head projection?
Below radius
