In trauma cases the suitable projection to demonstrate proximal humerus.. Transthoracic lateral

In trauma cases the suitable projection to demonstrate proximal humerus:

  • A. AP supine
  • B. AP Erect
  • C. Transthoracic lateral
  • D. PA Erect.

For demonstrating the proximal humerus in trauma cases, the most suitable projection is C. Transthoracic lateral.

Here's why:

Transthoracic lateral:

  • Provides a clear visualization of the entire proximal humerus, including the head, neck, and tuberosities.
  • Shows the relationship of the humerus to the glenoid cavity and scapula.
  • Allows for assessment of fractures, dislocations, and other abnormalities.

Other options:

- AP supine:

Limited view of the proximal humerus, as the scapula may overlap it.

- AP Erect:

Similar to AP supine, with additional risk of obscuring the proximal humerus by the clavicle.

- PA Erect:

Not ideal for trauma cases, as it doesn't offer the necessary detail for assessing fractures and dislocations.

Additional notes:

  • In some cases, additional views such as an axillary view or an internal rotation view may be needed for a complete assessment of the proximal humerus.
  • The choice of projection will ultimately depend on the specific clinical situation and the suspected injury.
