Elbow radiographs for dysplasia evaluation typically require how many views per elbow?

• A. 1 view
• B. 2 views
• C. 3 views
• D. 4 views

Answer: (C)

Evaluating elbow dysplasia needs seeing the joint from multiple angles to appreciate how the articular surfaces and bones align in three dimensions. The typical radiographic set includes three views: an AP (craniocaudal) view to assess joint space and frontal alignment, a lateral view to examine the relationship of the bones when the elbow is flexed, and an oblique view to reduce overlap and better visualize the trochlear groove, coronoid process, and radial head. This combination provides complementary perspectives that make it possible to detect incongruity, subluxation, or fragmentary changes that might be missed on a single or two views. Hence, three views per elbow is the standard approach.
