Which projection is described as opening the joint spaces with a cephalic angle for the fifth digit?

• A. AP projection
• B. Lateral projection
• C. Oblique projection
• D. PA projection

Answer: (A)

Opening the joint spaces in the fifth digit is best achieved with an AP projection that uses a slight cephalad angle. This small tilt helps align the beam with the toe’s anatomy so the spaces between the phalanges and between the toe and metatarsal can be seen without overlapping bones. That joint-space clarity is crucial for evaluating fractures or joint pathology in the little toe. The other views—lateral, oblique, or PA—don’t routinely employ this cephalad angulation to maximize joint-space visibility in the fifth digit, and they either show the toe from a different perspective or don’t optimize the joint spaces in the same way.
