Shoulder joint

Glenoid cavity

1. Patient in supine or upright position;
2. Rotate the patient 30-40º toward the affected side;
3. Abduction of the arm and rest the palm of the hand on the abdomen.

Central ray angled at 15º minimum caudad to the coracoid process.

Respiration: Suspended.

Evaluation Criteria:

• Visualization of the joint space between humeral head an glenoid cavity;
• Glenoid cavity in profile;
• Sub-acromial space open (acromion and clavícul overlapped);
• Espaço sub-acromial aberto pois o acrômio e a clavícul estão sobrepostos;
• Appropriate exposure values (visualization of the all bony trabeculation and soft tissue).

 

AP Projection

1. Patient in supine or upright position;
2. Rotate slightly (15º) toward the affected side;
3. Hand in:

• External rotation;
• Neutral rotation;
• Internal rotation.

Central ray perpendicular to the coracoid process.

 External Rotation

Internal Rotation

Evaluation Criteria:

• Visualization of the superior scapula, lateral half of the clavicle and proximal humerus;
• In external rotation:
• Humeral head and greater tubercle in profile;
• Outline of lesser tubercle between the humeral head and greater tubercle;
• Neutral rotation:
• Greater tubercle partially superimposing the humeral head;
• Internal rotation:
• Lesser tubercle in profile and medially;
• Greater tubercle superimposed the humeral head.
• Appropriate exposure values (visualization of the all bony trabeculation and soft tissue).
