DIAL in talar OCD lesions describes which shape?

• A. Wafer-shaped
• B. Cup-shaped
• C. Dome-shaped
• D. Flat

Answer: (A)

DIAL is a descriptor used for the shapes of talar osteochondral defects on imaging. It identifies several patterns, including a wafer-shaped appearance, which is a thin, plate-like lesion along the talar dome. This means the defect is flat and shallow, with minimal depth into the subchondral bone. Imaging shows a slim, planar defect that resembles a wafer. This is distinct from dome-shaped (a rounded bump), cup-shaped (a crater-like concavity), or flat (a broader, uniform plane) patterns. Recognizing the wafer-shaped pattern helps in understanding the lesion’s depth and guides appropriate treatment considerations.
