  • Metatarsal phalangeal sesamoid prosthetic joint
    Patent number: 5776203
    Abstract: A prosthetic or artificial joint for replacing the natural metatarsal-phalangeal-sesamoid joint of the human toe has a phalangeal component that provides an articulating base platform for a metatarsal component to glide upon. The metatarsal component articulates against a gliding articular insert recessed in the base of the phalangeal component. The base of the phalangeal component has an elongated groove which divides the base into two portions which simulate the function of the sesamoids and offers mechanical advantage to the metatarsal component as it articulates. The groove also allows the flexor halucis brevis tendon to pass beneath the joint between the two artificial sesamoids.
