This is useful in diagnosing cases of posterior dislocation

Shoulder Joint - AP Axial Projection

A projection useful for the evaluation of suspected shoulder dislocations

Scapular Y - PA Oblique Projection - RAO / LAO Position

Midcoronal plane angulation for Scapular Y PA Oblique Projection

45 - 60 Degrees

Anterior Dislocations = The humeral head is beneath the ________ process

Posterior Dislocations = The humeral head is beneath the _______ process

Anterior = CORACOID process

Posterior = ACROMION process

What projection shows the joint space between the humeral head and the glenoid cavity through abducting the arm slightly in internal rotation and placing the palm of the hand on the abdomen ?

AP Oblique Projection - Grashey Method - RPO/LPO Position

RP for Grashey Method

Glenoid Cavity

(2 inches Medial and 2 inches Inferior to the Superolateral Border of the Shoulder)

What method is similar to the Grashey Method but uses weighted abduction to demonstrate a loss of articular cartilage in the scapulohumeral joint ?

Apple Method

What projection and method is used to evaluate acute shoulder trauma and for identifying posterior scapulohumeral dislocations, glenoid fractures, Hill-Sachs lesions, and soft-tissue calcifications ?

AP Axial Oblique Projection - Garth Method - RPO/LPO Position

CR and RP for Apple Method

CR = Perpendicular RP = Coracoid Process

CR and RP for Garth Method

CR = 45 Degrees Caudad RP = Scapulohumeral Joint

Projection and method used to demonstrate dislocation, separation, and function of the joints

AP Projection - Bilateral - Pearson Method

SID for Bilateral - Pearson Method

72 Inches (183 cm)

Projection and method which project the acromioclavicular joint and clavicle above the acromion

AP Axial Projection - Alexander Method

CR and RP for AP Axial Projection - Alexander Method

CR = 15 Degrees RP = Coracoid Process

Projection and method used to demonstrate the acromioclavicular joint and the relationship of the bones of the shoulder

PA Axial Oblique Projection - Alexander Method

CR and RP for PA Axial Oblique Projection - Alexander Method

CR = 15 Degrees Caudad RP = Acromioclavicular Joint

Projection that provides frontal image of the clavicle BONUS Ques: What is the RP of the aforementioned projection ?

AP Projection RP = Midshaft of the Clavicle

Clavicle projection most useful when improved recorded detail is desired as it brings the clavicle to the IR, thus reducing OID

PA Projection

What projection leans the patient backward in a position of extreme lordosis, with the neck rested and shoulder against the VCH ?

AP Axial Projection - Lordotic Position

Complete the following CR angulations for the provided AP Axial Projection variations of the Clavicle: AP Axial - Lordotic = AP Standing = AP Recumbent =

AP Axial - Lordotic = Perpendicular AP Standing = 0 - 15 Degrees AP Recumbent = 15 - 30 Degrees

In the AP Projection of the Scapula, the body must not be rotated towards the affected side because the resultant obliquity would ______ the effect of drawing the scapula ______

1. Offset 2. Laterally

CR and RP for AP Scapula

CR = Perpendicular RP = Midscapular Area (2 inches inferior to the Coracoid Process)

For delineation of the acromion and coracoid process, have the patient _______ and _________

1. Flex the elbow 2. Place the back of the hand on the posterior thorax

For demonstration of the body of the scapula, ask the patient to ______ and ________ on the head or across the upper chest by grasping the opposite shoulder

1. Extend the arm upward 2. Rest the forearm

What are the two methods for PA Oblique projection of the Scapula ?

1. Lorenz Method 2. Lilienfeld Method
