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 : • IR size—24 × 30 cm (10 × 12 inches), crosswise (or lengthwise to demonstrate entire humerus if injury includes proximal half of humerus)
SID: 100cm
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. • Collimation to area of interest.
Exposure: • Optimal density (brightness) and contrast with
no motion demonstrate clear, sharp bony trabecular markingswith soft tissue detail visible for possible calcium deposits
pathology demonstrated :
Fractures or dislocations of proximal
humerus
• Fractures of glenoid labrum or brim
• Bankart lesion, erosion of glenoid rim, the
integrity of the scapulohumeral joint, and other degenerative conditions
IR size : IR size—18 × 24 cm (8 × 10 inches), crosswise
crosswise \ inpucky
Shield radiosensitive tissues outside region of interest.
Patient position :
Perform radiograph with patient in an erect or
supine position. (The erect position is usually less painful for patient, if condition allows.)
Part position:
• Rotate body 35° to 45° toward affected side (see Note). If the
radiograph is performed with the patient in the supine position,
place supports under elevated shoulder and hip to maintain this
position.
• Center midscapulohumeral joint to CR and to center of IR.
• Adjust cassette so that top of IR is about 2 inches (5 cm) above
shoulder and side of IR is about 2 inches (5 cm) from lateral
border of humerus.
• Abduct arm slightly with arm in neutral rotation.
CR : CR perpendicular to IR, centered to scapulohumeral joint, which
is approximately 2 inches (5 cm) inferior and medial from the superolateral border of shoulder
Collimation
Collimation : Collimate so that upper and lateral borders of the field are to the soft tissue margins.
criteria :
Anatomy Demonstrated: • Glenoid cavity should be seen in
profile without superimposition of humeral head.
Position: • Scapulohumeral joint space should be open.
• Anterior and posterior rims of glenoid cavity are superimposed.
• Collimation to area of interest.
Exposure: • Optimal density (brightness) and contrast with
no motion visualize soft tissue margins and clear, sharp bony
trabecular markings. • Soft tissue detail of the joint space and axilla should be visualized.
Pathology demonstrated :
Optimal trauma projection for possible
scapulohumeral dislocations (especially
posterior dislocations)
• Glenoid fractures, Hill-Sachs lesions, and soft tissue calcifications*
IR size : IR size—24 × 30 cm (10 × 12 inches), lengthwise
Shield radiosensitive tissues outside region of interest
lengthwise \ inpucky
Patient position :
Perform radiograph with patient in erect or supine
position. (The erect position is usually less painful, if patient’s condi-
tion allows.) Rotate body 45° toward affected side (posterior
surface of affected shoulder against IR).
Part position:
Center scapulohumeral joint to CR and mid-IR.
• Adjust IR so that 45° CR projects scapulohumeral joint to the
center of IR.
• Flex elbow and place arm across chest, or with trauma, place
arm at side as is.
CR : CR 45° caudad, centered to scapulohumeral joint
Collimation : Collimate closely to area of interest.
criteria :
Anatomy Demonstrated: • Humeral head, glenoid cavity, and
neck and head of the scapula are well demonstrated free of
superimposition.
Position: • The coracoid process is projected over part of the
humeral head, which appears elongated. • Acromion and AC
joint are projected superior to the humeral head. • Collimation
to area of interest.
Exposure: • Optimal density (brightness) and contrast with
no motion demonstrate clear, sharp bony trabecular markings and soft tissue detail for possible calcifications.
