Axillary view of shoulder  

The axillary view is useful for detecting anterior or posterior shoulder dislocations that are not evident in the AP view. The x-ray beam is directed into the axilla from below (inferior to superior), or down through the axilla from above the shoulder (superior to inferior). Notice in this image how you can evaluate the alignment of the humeral head with the glenoid cavity (in this film they are aligned - there is no dislocation).

Identify the following:

1. clavicle

2. acromion

3. head of humerus

4. glenoid cavity

5. coracoid process
