Os intermetatarseum - A case report.

Accessory ossicles and sesamoid bones are skeletal variations, more commonly seen in the region of foot and ankle. Most such accessory and sesamoid bones remain asymptomatic. However overuse and trauma can make such feet symptomatic. Knowledge of such bony ossicles is essential in the management of patients presenting with foot pain. Dorsal foot pain can be caused by a symptomatic Os intermetatarseum - an accessory ossicle found between the bases of first and second metatarsals and the medial cuneiform. Its incidence has not been well established because of insufficient appropriate multi-centric anatomical, radiological and orthopaedic studies. A case of dorsal foot pain in a soccer player, caused by an Os intermetatarseum is reported here. A brief review of the literature is also presented.
