Pathology demonstrated : 

linical Indications

• Fractures or dislocations of proximal humerus and shoulder girdle

• Calcium deposits in muscles, tendons, or bursal structures

• Degenerative conditions including osteo-porosis and osteoarthritis.

IR Size : 

 24 × 30 cm (10 × 12 inches)

IR Position : 

Crosswise / inbucky

Sheilding : 

Shield radiosensitive tissues outside region of interest.

Patient Position :

Perform radiograph with the patient in an erect or supine position. (The erect position is usually less painful for patient, if condition allows.) Rotate body slightly toward affected side, if necessary, to place shoulder in contact with IR or tabletop

Part Position : 

Position patient to center scapulohumeral joint to center of IR.

• Abduct extended arm slightly; internally rotate arm (pronate hand) until epicondyles of distal humerus are perpendicular to IR.

CR : 

CR perpendicular to IR, directed to 1 inch (2.5 cm) inferior to coracoid process (see Note on preceding page)

Collimation : 

 Collimate on four sides, with lateral and upper borders adjusted to soft tissue margins

Criteria : 

Anatomy Demonstrated: • Lateral view of proximal humerus and lateral two-thirds of clavicle and upper scapula is demonstrated, including the relationship of the humeral head to the glenoid cavity.

Position: • Full internal rotation position is evidenced by lesser tubercle visualized in full profile on the medial aspect of the humeral head. • An outline of the greater tubercle should be visualized superimposed over the humeral head.
