Which patient position is correct for a medial oblique fifth digit radiograph?

• A. Sitting
• B. Standing
• C. Prone
• D. Supine

Answer: (A)

Positioning hinges on controlled rotation of the hand to create the medial oblique view of the fifth digit. To achieve this, you rotate the hand toward the midline (medially) while the forearm rests securely, usually with the patient seated so you can stabilize the hand on a table. The seated position allows precise, repeatable rotation—about 45 degrees—without the balance and movement challenges that can come with standing, or the awkward limb angles that come with lying prone or supine. This medial rotation opens the area between the bones of the little finger and minimizes superimposition from adjacent digits, giving a clearer image of the fifth digit’s bones and joints. Standing is less stable for maintaining that exact oblique angle, and prone or supine positions complicate hand placement and rotation, making the desired view harder to achieve consistently.
