Chapter 5 - Quizlet one Flashcards
An optimal AP clavicle projection demonstrates all of the following except the
a.middle and lateral thirds of the clavicle seen superior to the acromion process.
b. midclavicle in the center of the IR.
c. midclavicle superimposing the superior scapular angle.
d. medial clavicular end adjacent to the vertebral column.
a. middle and lateral thirds of the clavicle seen superior to the acromion process.
A PA oblique scapular Y shoulder projection that was obtained w/ the patient overrotated demonstrates the:
1. medial scapular border closer to the ribs than the lateral scapular border.
2. superior scapular angle superior to the clavicle.
3. lateral scapular border closer to the ribs than the medial scapular border.

An AP shoulder projection demonstrating longitudinal foreshortening of the scapular body can occur when the:
a. patient is positioned PA.
b. patient’s upper midcoronal plane is tilted away from the IR.
c. patient is rotated onto the affected shoulder.
d. affected shoulder is elevated.
b. patient’s upper midcoronal plane is tilted away from the IR.
A PA oblique scapular Y shoulder projection with accurate positioning demonstrates
1. the superior angle of the scapular at the same transverse level as the clavicle.
2. superimposed scapular borders.
3. a laterally situated glenoid fossa.
4. the coracoid, acromion, and humerus creating the arms and leg of the Y formation.
1 & 2 only
In a properly positioned AP Shoulder, internal rotation, which of the following is not an evaluation criteria:
a. glenoid cavity partially superimposed by the humeral head
b. minimal distortion of the scapula and clavicle.
c. lesser tubercle in profile medially
d. greater tubercle in profile laterally
d. greater tubercle in profile laterally
The arms of the Y on a PA oblique scapular Y shoulder projection are formed by the
1. coracoid.
2. scapular body.
3. acromion.
4. glenoid fossa.
1 & 3 only
An AP oblique shoulder projection (Grashey method) obtained with the patient rotated less than required to obtain accurate positioning demonstrates:
a. increased superimposition of the thorax over the scapular neck.
b. a closed glenohumeral joint.
c.more than 0.25 inch of the coracoid superimposed over the humeral head.
d. elongation of the clavicle.
b. a closed glenohumeral joint.
A poorly positioned AP shoulder projection demonstrating most of the articulating surface of the glenoid cavity
a.was obtained because the patient was rotated toward the affected shoulder.
b. was obtained because the upper midcoronal plane was tilted posteriorly.
c.will also demonstrate the medial clavicular end superimposing the vertebrae.
d. will also demonstrate longitudinal foreshortening of the scapular body
c. will also demonstrate the medial clavicular end superimposing the vertebrae.
An AP clavicle projection obtained with the patient rotated toward the affected shoulder demonstrates the:
1. medial clavicular end superimposed over the vertebral column.
2. medial clavicular end shifted away from the vertebral column.
3. clavicle is foreshortened
4. clavicle is elongated.
