Abstract:
1. A double-hooded enarthrodial joint implant cup ensemble comprising: a ball-receiving cup having an articular surface upon which a ball of a joint can articulate, and which has a margin generally about a hemisphere, and two and only two generally opposing hoods that are marginally extended continuations of superior about one-half of cup containment of a sufficient magnitude to reduce an overall dimension of socket outlet to less than a hemisphere, which can embrace and contain the ball; and a securing member that provides for resistance against outward displacement of at least one of the two hoods so that the ball can be securely contained in the embrace of the two hoods; wherein the securing member provides for resistance against outward displacement of both of the two hoods, and has a body in a form of a ring with two and only two braces, which generally oppose one another, connected to and projecting substantially perpendicularly away from a plane formed by the body, with both hood braces projecting on the same side of the plane; each of the hood braces is provided with a cover that extends inwardly toward the center of the ring from an end of the hood brace away from the ring; and an inwardly biased engagement tab is provided for at least one of the two hood braces, which can engage material of the cup about the hood so as to secure the ring to the cup, and which is present in the at least one of the two hood braces between the plane formed by the body in the form of the ring and the cover that extends inwardly toward the center of the ring from the end of the hood brace away from the ring.
