What anatomy is best demonstrated in a PA olique wrist?
|
Trapezium and Scaphoid
|
|
What anatomy is best demonstrated in an AP olique wrist?
|
Pisiform, triquetrum, and hook of hamate
|
|
Central ray for digits 2-5:
|
Perpendicular to PIP joint
|
|
Why is an AP forearm preferred over a PA?
|
PA results in an oblique projection; radius is crossed over the ulna at the proximal end.
|
|
Why is it important to have the thump extended superiorly in a lateral forearm projection?
|
To demonstrate the radial tuberosity most superior.
|
|
Which projection of the elbow best demonstrates the coronoid process in profile?
A. Lateral elbow
B. AP elbow
C. AP lateral oblique elbow
D. AP medial oblique elbow
|
D. AP Medial Oblique Elbow
(This also shows the olecrannon process w/i the fossa)
|
|
Is the capitulum located on the medial or lateral side of the elbow?
|
Lateral side
(Remember: The cap (capitulum) goes on the head (of the radius))
|
|
What is the location of the lesser tubercle in an AP internal shoulder?
|
On medial side of humerus
|
|
In an axillary shoulder, what is projected anteriorly and seen in profile?
|
Lesser tubercle
|
|
How much do you angle and in what direction for an AP Axial AC joint projection?
|
15 degrees cephalic
|
|
On an AP Axial Clavicle, how much is your cephalic angle and why?
|
15-30 degrees cephalic to project the clavical off of the scapule and ribs.
(Thinner pts require more angle).
|
|
How is the pt positioned for an AP Scapula and what is the CR?
|
Pt is sitting with their back against IR and arm on affected side is extended laterally with elbow flexed in 90 degree angle. CR is 2" inferior to the corocoid process.
|
|
What make up the "Y" in a lateral scapula projection?
|
Acromian, corocoid process, and body of scapula.
(Most schools preferr shoulder in a RAO of LAO position to place scapula closer to IR)
|
|
What is the position of the mouth in an AP open mouth projection?
(What should be alligned)
|
Open wide with the bottom of the incisors alligned with the bottom of the mastoid processes.
|
|
For an AP axial & posterior oblique projections of the c-spine, what is the angle of the CR and why?
|
15-20 degrees cephalic, Opens up the disk space and better demonstrates formina farthest from IR.
