Question

What is the proper relationship of the humeral epicondyles with the IR for the lateral projection of the humerus?

Select one:
a.Parallel
b.Perpendicular
c.From true anatomic position, 45-degree medial rotation
d.From true anatomic position, 45-degree lateral rotation

Answer 1

For a lateral projection of the humerus, the humeral epicondyles should be perpendicular to the IR to ensure a true lateral view, which is essential for correct diagnosis.

Step-by-step explanation:

For the lateral projection of the humerus, the proper relationship of the humeral epicondyles to the Image Receptor (IR) is to have the epicondyles perpendicular to the IR.

This positioning ensures that a true lateral view of the humerus is obtained, which is crucial for proper diagnosis and analysis of the humerus itself and the surrounding joint structures. It provides a clear view of the humeral shaft along with the lateral and medial epicondyles, which are important for muscle attachments and articulation with other bones in the elbow region.
