ABSTRACT
Sesamoid bones and secondary centers of ossification account for the accessory bones
of the foot, and there is a wide range of frequency with which these different ossicles
appear. They are usually incidental asymptomatic findings on imaging studies, and
their clinical importance lies in not mistaking them for fractures. Occasionally these
ossicles can become painful due to fracture, degenerative changes, avascular necrosis,
and irritation or impingement of adjacent soft tissue.
