Complete Agenesis of Both Metatarsophalangeal Sesamoids with Contralateral Agenesis of Fibular Sesamoid Associated with Hallux Valgus
he metatarsophalangeal joint of the great toe differs from that of the lesser toes because it has a sesamoid mechanism and a set of intrinsic muscles that stabilize the joint and provide motor strength to the first ray. The hallucal sesamoids are a consistent entity in humans, originating in the tendons of flexor hallucis brevis. They appear within the seventh or eighth week of embryonic development as islands of undifferentiated connective tissue.
