What is another name for the tangential, supraspinatus outlet projection?
Neer Method
A referring physician suspects that a subacromial spur may be the cause for a patient's shoulder impingement. She asks the technologist for a projection that would best demonstrate any possible spurs in the supraspinatus outlet. Which projection would accomplish this objective?
Tangential projection with 10o-15o caudad angle
The PA transaxillary (Hobbs Modification) requires a 5 to 15 degree CR cephalic angle.
False. CR is directed perpendicular to the axilla and the humeral head to pass through the scapulohumeral joint.
Where is the CR centered for the AP oblique (Grashy method) position for the glenoid cavity?
2" medial and inferior to the superolateral border of shoulder
A patient enters the ED with multiple injuries including a possible fracture of the left proximal humerus. Which positioning rotation should be performed to determine the extent of the humerus injury?
AP and horizontal beam transthoracic lateral shoulder projection
What is another name for the inferior axial projection?
Clements Modification
Which projection can be performed using an orthostatic (breathing) technique?
AP scapula
The Hill-Sachs defect is a fracture of the articular surface of the glenoid cavity.
False. The Hill-Sachs defect is a compression fracture of the articular surface of the posterolateral aspect of the humeral head that is associated with an anterior dislocation of the humeral head.
Where is the CR centered for a transthoracic lateral projection for proximal humerus?
Level of surgical neck
Which of the following shoulder positions is considered a trauma projection (can be performed safely for a possible fracture or dislocation of the proximal humerus)?
AP apical oblique axial (Garth method) projection
What is another name for the AP oblique, glenoid cavity projection?
Grashy Method
This shoulder position is considered a trauma projection (can be performed safely for a possible fracture or dislocation of the proximal humerus)?
AP apical oblique axial (Garth Method) projection
The PA transaxillary projection (Hobbs Modification) is performed to rule out possible shoulder dislocation.
False. It is to rule out fractures or dislocations of the proximal humerus.
Where is the CR centered for the bilateral acromioclavicular (AC) joint projection on a single 14 x 17" image receptor?
1" above the jugular notch.
What additional maneuver must be added to the inferosuperior axial shoulder (Lawrence method) projection to best demonstrate a possible Hill-Sachs defect?
Perform exaggerated external rotation of the affected upper limb.
What is another name for the AP apical oblique axial projection?
Garth Method
This projection will best demonstrate the acromiohumeral spaces to detect possible spurring?
Apical AP axial projection
For AC joint weight-bearing studies, patients should not be asked to should on to the weights with their hands; rather, the weights should be attached to the wrists.
True
How much CR angulation is required for an asthenic patient for an AP axial projection of the clavicle?
30 degrees
An AP apical oblique (Garth Method) projection for an anteriorly dislocated scapulohuermal joint will project the humerus ____ to the glenoid cavity?
Inferior
What is another name for the tangential, intertubercular sulcus projection?
Fisk Modification
Which projection/position should NOT be performed for a possible shoulder dislocation?
Inferosuperior axial (Clements modifications)
For an AP oblique (Grashy Method) projection of the shoulder, the CR is centered to the acromion.
False. The CR is centered midscapulohumeral joint and centered to IR.
The inferosuperior axial projection (Clements modification) requires a CR angle of _____ toward axilla if a patient cannot fully abduct extremity 90o.
5o to 15o
A patient comes to the emergency department (ED) with a possible right AC joint separation. Right clavicle and AC joint examinations are ordered. The clavicle is taken first, and a small linear fracture of the midshaft of the clavicle is discovered. What should the technologist do in this situation?
Consult the ED physician before continuing with the AC joint study.
