Positions
This is an AP projection of the shoulder with the arm abducted slightly, hand supinated
Ap Projection, External Rotation (True AP Shoulder)
In this view of the shoulder, the epicondyles are perpendicular to the IR.
AP Projection, Internal rotation (Lateral)
This view of the humerus and shoulder will show the greater tubercle in profile.
AP Projection, External rotation (True AP) It is seen on the lateral side.
This view requires the CR to be directed 25 to 30 degree medially into the arm pit.
Inferosuperior Axial Projection (Axillary) Lawrence Method.
The coracoid is a process found here.
Scapula
On this radiograph, you may see a compression fracture and possible anterior dislocation of humeral head.
Hill-Sachs defect.
(Best seen on AP internal rotation, Exaggerated external rotation, or transaxillay view)
This joint is a double plane, or gliding joint because the sternal end of the clavicle articulates with the manubrium or upper portion of the sternum and the cartilage of the first joint.
Sternoclavicular joint.
This is an AP projection of the shoulder with the hand pronated and placed behind the thigh
AP Projection, Internal Rotation (LATERAL)
This projection will show the humeral head sitting in the junction of the glenoid cavity.
Y-View (Scapular Y View, PA Oblique Projection)
In this view of the shoulder, the scapulohumeral joint will be open.
Grashey Method (AP Oblique Projection)
This view requires a 35 to 45-degree patient rotation toward the affected side
Grashey Method (AP Oblique Projection)
The coranoid process can be found here.
Radius
On this radiograph, you may see a loss of joint space, bony erosion, and bony deformity.
Rheumatoid arthritis.
(Best seen AP and Lateral Shoulder)
This ball and socket joint involves the articulation between the head of the humerus and the glenoid cavity of the scapula.
Scapulohumeral Joint (Shoulder Joint).
This shoulder view is done in an LPO or RPO position or an AP projection.
Grashey (AP Projection)
In this projection, the patient will place the unaffected arm over their head, drop the affected shoulder while raising the unaffected shoulder to prevent superimposition.
Transthoracic Lateral Projection (Trauma)
This view will show neither the greater tubercle nor lesser tubercle in profile.
AP Projection, Neutral Position (Trauma AP)
This view requires a patient rotation of 45 to 60 degrees with the affected side touching the IR.
Scapular Y Lateral (PA Oblique Projection)
These processes make up the top of the Y in the Y-view of the shoulder?
The acromion and the coracoid
On this radiograph, you may see fluid-filled joint space with possible calcification.
Bursitis.
(Best seen on AP and Lateral Shoulder)
This plane, or gliding movement type joint between the acromial end of the clavicle and the medial aspect of the acromion of the scapula. Some secondary movement occurs as the scapula moves forward and backward with the clavicle.
Acromioclavicular Joint.
This is a PA projection but an LAO or RAO position of the shoulder
Y-view (PA Oblique Projection)
In this position of the shoulder and humerus, the epicondyles are parallel to the IR.
AP Projection, External rotation (True AP)
This view of the humerus and shoulder will show the lesser tubercle in profile.
AP Projection, Internal Rotation (Lateral). It is seen on the medial side
This view is done specifically for evaluating the alignment of the humerus with the scapula.
Y-View (Scapular Y view, PA Oblique Projection).
This area of the humerus is fractured the most. There are 2 of these on the humerus, but this one is named for this reason.
Surgical neck
On this radiograph, you may see a small avulsion fracture of the anteroinferior aspect of the glenoid fossa.
Bankart Lesion.
(Best seen on AP internal rotation, PA oblique or y-view, and AP Oblique or Grashey)
This type of joint is freely moveable.
Diarthrodial.
This is a supine position, or an inferosuperior projection, of the shoulder with the arm extended 90 degrees away from the body.
Axial or axillary shoulder
This position requires the hand to be in a natural position, the hand is usually against the thigh. The arm should not be rotated.
AP Projection, Neutral Position
This view of the shoulder will show you the coracoid process of the scapula and lesser tubercle of the humerus in profile and the glenoid cavity on end.
Inferosuperior axial Projection (axillary view)
This view will show a fracture of the diaphysis of the humerus.
Transthoracic Lateral Projection.
The deep groove between the greater and lesser tubercle.
Intertubercular sulcus (bicipital groove).
On this radiograph, you may see that the humeral head has moved from its original position in the glenoid cavity.
Shoulder Dislocation.
(Best seen on PA Oblique (y-view), Transthoracic Lateral, or Garth Method).
The three joints in the shoulder are classified as this type of joint that is characterized by a fibrous capsule.
Synovial Joint, which contains synovial fluid
