Which type of projection is used to view the sesamoids of the toes?

The tangential projection is specifically designed to demonstrate structures that may be obscured by adjacent anatomy, and it is particularly useful for viewing the sesamoids of the toes. In the context of the foot, this projection allows radiologists to clearly visualize the sesamoid bones, which are small, round bones found within the tendons of the flexor hallucis brevis muscle at the base of the big toe. By positioning the foot in a way that brings the sesamoids into profile, the tangential projection minimizes superimposition and enhances the clarity of the image.

Additionally, this projection involves directing the x-ray beam parallel to the surface of the structure being examined, which is critical for accurately capturing the anatomy of the sesamoids without interference from surrounding structures. This technique is essential in diagnosing conditions related to the sesamoids, such as fractures or dislocations.
