Which view is best for diagnosing dislocations in the shoulder?

The axillary and Y-view are considered the best imaging techniques for diagnosing shoulder dislocations because they provide a comprehensive view of the glenohumeral joint and surrounding structures. The axillary view allows for visualization of the joint space between the humeral head and the glenoid, which is crucial for identifying any dislocation or misalignment. This view helps in determining whether the humeral head is anterior or posteriorly displaced.

The Y-view, also known as the scapular Y-view, offers a lateral perspective of the shoulder. It creates a "Y" shape that includes the scapula and assesses the relationship of the humeral head relative to the glenoid. This view enhances the ability to visualize the positioning of the shoulder structures and can reveal any dislocation more effectively than other standard views.

In contrast, while frontal and lateral views provide some information about the shoulder joint, they are less effective in clearly demonstrating dislocations. A frontal view may not provide adequate details on the positioning of the humeral head, and the lateral view, though helpful for certain assessments, is often not sufficient alone for a comprehensive evaluation of dislocations. X-rays with contrast are generally used for different types of imaging situations, such as assessing complications or for more detailed visualization of
