Sesamoids of the foot

Sesamoids are inter-tendinous bones and the constant ones are the medial and lateral sesamoids of the first metatarsophalangeal joint. Accessory sesamoids occur elsewhere and are rare. Sesamoiditis, infection, fracture and bipartite sesamoid are the common associated conditions. Treatment should be conservative in the first instance. Sesamoidectomy may be necessary but removal of both big toe sesamoids in contra-indicated.
