Exam 5: Humerus and Shoulder Girdle

A patient enters the ED with a possible AC joint separation.The patient is paraplegic; therefore, the study cannot be done erect.Which of the following routines would be performed to diagnose this condition?

Which of the following shoulder projections best demonstrates the glenoid cavity in profile?

Part 3 refers to the greater tubercle.

Which of the following best demonstrates the coracoacromial arch?

A patient enters the ED with a midshaft humeral fracture.The AP projection taken on the cart demonstrates another fracture near the surgical neck of the humerus.The patient is unable to stand or rotate the humerus because of the extent of the trauma.What other projection should be taken for this patient?

Which of the following projections will best demonstrate the acromiohumeral space to detect possible spurring?

Where is the CR centered for a transthoracic lateral projection for proximal humerus?

Which AP projection of the shoulder and proximal humerus is created by placing the affected palm of the hand facing inward toward the thigh?

The inferosuperior axial projection (Clements modification) requires a CR angle of ____ toward axilla if a patient cannot fully abduct extremity 90°.

Which of the following AP shoulder projections demonstrates the greater tubercle in profile medially?

Part 5 refers to:

The AP axial (Alexander method) for AC joints requires a 15° cephalic CR angle.

What is the name of the insertion point for the deltoid muscle located on the anterolateral surface of the humerus?

A radiograph of an AP clavicle reveals that the sternal extremity is partially collimated off.What should the technologist do?

A patient enters the ED with multiple injuries.The physician is concerned about a dislocation of the left proximal humerus.The patient is unable to stand.Which of the following routines is advisable to best demonstrate this condition?

What type of CR angle is required for the apical AP axial projection?

A radiograph for an AP projection with external rotation of the proximal humerus reveals that the greater tubercle is profiled laterally.What should be changed to improve this image for a repeat exposure?

Which term describes the medial end of the clavicle?

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 suprasinatus outlet.Which of the following projections would accomplish this objective?
