For a radiograph of the sesamoids using the Holly method, how should the foot be positioned?

When performing a radiograph of the sesamoids using the Holly method, the correct positioning of the foot requires dorsiflexion. This positioning allows the sesamoid bones, particularly the hallux sesamoids, to be more readily visible and to be adequately separated from the first metatarsal. Dorsiflexing the foot tends to reduce the superimposition of surrounding structures, thus providing a clearer image.

This technique is particularly important in analyzing the hallux and its supportive structures, as proper positioning helps highlight any potential abnormalities or injuries within these specific bones. By keeping the foot dorsiflexed, the radiographer ensures that the sesamoids are on a clearer plane relative to the x-ray beam, maximizing diagnostic efficiency for the assessment of these commonly injured bones.
