Abstract
A system is provided which includes an articulating component, a post, a reception member and a bone engaging member. The articulating component includes an articulating surface and a second surface opposite the articulating surface. The post is disposed below the second surface. The reception member is configured to receive the post. The bone engaging member is configured to be embedded in a bone, wherein the bone engaging member is configured to receive the reception member. The reception member includes a reception member inside surface, wherein the reception member inside surface faces the post when the post is received by the reception member. A first portion of the reception member inside surface defines a tapered configuration and the reception member inside surface comprises at least one ratchet interface.
Claims19
A system, comprising:
- an articulating component comprising an articulating surface and a second surface opposite the articulating surface;
- a post disposed below the second surface;
- a reception member configured to receive the post;
- and
- a bone engaging member configured to be embedded in a bone, wherein the bone engaging member includes a bore that is configured to receive an anchor, the anchor being configured to couple the bone engaging member to the bone, wherein the bone engaging member is configured to receive the reception member in the bore above the anchor;
- wherein the reception member comprises a bore extending from a proximal end to a distal end of the reception member, a reception member inside surface, wherein the reception member inside surface faces the post when the post is received by the reception member, and wherein the reception member comprises at least one installation-extraction through-hole, wherein the installation-extraction through-hole extends from the reception member inside surface away from the bore to an outside surface of the reception member, wherein the outside surface faces the bone engaging member;
- at least a first portion of the reception member inside surface defines a tapered configuration;
- and
- the reception member inside surface comprises at least one ratchet interface.
A method comprising:
- embedding a bone engaging member in a bone wherein the bone engaging member includes a bore that is configured to receive and to engage an anchor;
- engaging the anchor with the bone engaging member to couple the bone engaging member to the bone;
- engaging a reception member in the bore of the bone engaging member above the anchor, wherein the reception member comprises a bore extending from a proximal end to a distal end of the reception member, a reception member inside surface comprising a first portion defining a tapered configuration, and the reception member inside surface comprises at least one ratchet interface, and wherein the reception member comprises at least one installation-extraction through-hole, wherein the installation-extraction through-hole extends from the reception member inside surface away from the bore to an outside surface of the reception member, wherein the outside surface faces the bone engaging member;
- engaging a post with the reception member, wherein at least one of the tapered configuration and the ratchet interface interfaces with a corresponding feature provided in the post;
- and
- engaging an articulating component with the reception member, wherein the post connects the articulating component with the reception member.
A system comprising:
- a bone engaging means configured to be embedded in a bone, wherein the bone engaging means includes a bore that is configured to receive an anchor, the anchor being configured to couple the bone engaging means to the bone;
- a reception means comprising a bore extending from a proximal end to a distal end of the reception member, an inside surface, wherein the inside surface is configured to provide at least one of an interference fit and a snap fit, wherein the reception means is configured to be received in the bore of the bone engaging means above the anchor, and wherein the reception means comprises at least one installation-extraction through-hole, wherein the installation-extraction through-hole extends from the reception means inside surface and extends away from the bore to an outside surface of the reception means, wherein the outside surface faces the bone engaging means;
- a connecting means configured to establish at least one of the interference fit and the snap fit with the reception means;
- and
- an articulating means configured to be engaged with the reception member using at least the connecting means.
