Which aid is used to dorsiflex a patient's toes when positioning for tangential sesamoids in the supine position?

• A. Foam Block
• B. Hand
• C. Goniometer
• D. Tape

Answer: (D)

To get a clear tangential view of the first metatarsophalangeal sesamoids, the toes need to be dorsiflexed so the sesamoids sit in profile and the beam can pass tangentially to them. The most reliable way to hold that position during exposure is with tape applied to secure the toes in dorsiflexion. Tape provides stable immobilization and minimizes movement, which is essential for a sharp, diagnostic image. Foam blocks can help with overall foot positioning but don’t reliably fix the toe angle, while using a hand to hold the toes risks movement and is not as consistent. A goniometer is a measuring tool, not a positioning aid.
