When obtaining radiographs for elbow dysplasia, how many views are indicated for each elbow?

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

Answer: (B)

Three views provide orthogonal perspectives so the elbow joint can be evaluated from different angles and structures aren’t obscured by overlapping bones. A lateral view shows alignment and any effusion or bone remodeling on the side, while a front-on (craniocaudal) view helps appraise the articulation between the humerus, radius, and ulna and detect surface irregularities. An oblique view further separates the bones to reveal parts of the joint that may be hidden in the other views. Together, these three views improve the ability to identify signs of elbow dysplasia, such as fragmentation or incongruity, more reliably than a single or two views.
