Os Intermetatarseum Revisited: A Case Report of Rare Variant and Review of Literature

Abstract

ABSTRACT Os intermetatarseum is the rarest accessory bone of the foot. It is usually found between 1st and the 2nd metatarsal bases arising typically from the base of the 2nd metatarsal. Only a few symptomatic cases have been reported in the literature, which were either unilateral or bilateral and radiographically they were of different shapes and sizes. We present a large, bilaterally symmetrical and unusual variant of os intermetatarseum. To our knowledge, such large, bilaterally symmetrical, fully formed os intermetatarseum, fusing to both metatarsals has not been described before. The case report also describes the surgical anatomy during the excision of os intermetatarseum and review of the literature to date. How to cite this article Rachha R, Gorva A.
