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.
