  • Front
  • Back
explain why a patient should be positioned in the PA projection for a clavicle
to place the clavicle closer to the IR
explain when a patient should not be positioned in a PA projection of the clavicle
if the patient cannot stand
explain how and where the CR is directed for an AP and PA axial projection of the clavicle
AP axial-directed to enter the mid shaft of the clavicle 0-15cephalad for standing lordoticand 15 to 30 cephalad for the supine.
describe the position for an AP axial projection of the clavicle
lordotic-the patient leads backward in a position of extreme lordosis and rest the neck and shoulder against the vertical grid device. the neck will be in extreme flexion
describe the difference between the Pearson and Alexander methods.
Pearson - 72" SID, CR perp, demonstrates dislocation, separation, and function of the joints.
explain why you should avoid having the patient hold weights in each hand
because this tends to make the shoulder muscles contract thus reducing the possibility of demonstrating a small AC separation
explain why both sides are x-rayed for AC joints
for comparison
explain the importance of abduction of the arm to a right angle to the body when doing and AP projection of the scapula
to move the scapula away from the ribs
explain why quiet breathing should be done during the exposure for an AP projection of the scapula
to obliterate lung detail
describe the lateral projection for a scapula
45 to 60 degree rotation from the plane of the IR
describe the direct lateral projection for the scapula with the patient supine
draw the arm across the chest, and adjust the body rotation to place the scapula perpendicular to the plane of the IR
describe the differences between the Lorenz and Lilienfeld methods
Lorenz - the arm of the affected side is as a right angle to the long axis of the body with the elbow flexed, rest the hand against the patients head
