Patent ID: 11583405

Abstract:
Multi-hooded enarthrodial joint implant has a hard substance articulating cup including a hard substance head-receiving cup having an articular surface upon which a head of a joint can articulate, and which, in general, has a margin generally about a hemisphere more or less and at least two hoods that are marginally extended continuations of superior one-half or so 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 head. The head is made of a hard substance and has a truncated generally circular cross section, a truncated surface with a feature for attachment of the stem, and an opposing articular surface for articulation against the articular surface of the ceramic head-receiving cup. As an ensemble, the cup is combined with the head, typically with a stem, for a total joint implant. The hard substance may be, for example, a composite substance, a metal or a metal alloy. Either the cup or the head, but not both, may be ceramic when employed in an ensemble.
