An intervertebral implant component of an intervertebral implant includes an outer surface for engaging an adjacent vertebra and an inner surface. A keel extends from the outer surface and is designed to be disposed in a slot provided in the adjacent vertebra. This keel extends in a plane which is non-perpendicular to the outer surface; and preferably there are two of the keels extending from the outer surface which are preferably offset laterally from one another. In another embodiment, an anterior shelf is provided at an anterior end of the outer surface, and this anterior shelf extends vertically away from the inner surface in order to help prevent bone growth from the adjacent vertebra towards the inner surface. Further in accordance with disclosed embodiments, various materials, shapes and forms of construction of the component and/or keel provide various benefits.

Provided is a novel joint replacement prosthesis that includes a base component, and one or more modular stems. The base component includes a bone-facing surface including one or more stem connectors configured for receiving and forming connections with the one or more modular stems inserted from the bone-facing surface side.

A glenoid implant includes a body, a plurality of fins, a collet, and a plug. The body has a central aperture therethrough and a plurality of slots. Each of the plurality of fins are coupled with a respective one of the plurality of slots of the boss of the body such that each of the plurality of fins is configured to move from a first generally inward position towards a second generally outward position. The collet including an interior threaded bore and a plurality of deflectable arms. The plug includes a threaded portion and a tip portion configured to engage with and cause the plurality of deflectable arms of the collet to move and cause the plurality of fins to move from the first generally inward position towards the second generally outward position, thereby aiding in securing the body to a scapula of a patient.

A reverse shoulder system can include, for example, a glenoid baseplate comprising a longitudinal axis, the glenoid baseplate further including a stem and a central channel within a sidewall of the stem. The stem can include a longitudinal axis. The longitudinal axis of the glenoid baseplate can be angled with respect to the longitudinal axis of the stem, wherein the longitudinal axis of the glenoid baseplate is not perpendicular with respect to the longitudinal axis of the stem. Other components including a glenosphere, tools, and methods of use are also disclosed.

A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.

This set comprising: an anatomic articulating member, having a concave articulating surface intended to articulate with a complementary humeral implant and having an anatomic coupling feature, a reversed articulating member, having a convex articulating surface intended to articulate with a complementary humeral implant and having a reversed coupling feature that is shaped differently from the anatomic coupling feature, and an anchorage member intended to be anchored in a human glenoid, the anchorage member including a body which defines a proximodistal axis and has inner bore extending along the proximodistal axis, the body being provided within the inner bore with both an inner first feature that is designed to cooperate with the anatomic coupling feature when the anatomic coupling feature is introduced within the inner bore, so as to fixedly couple the anchorage member with the anatomic articulating member, and an inner second feature that is designed to cooperate with the reversed coupling feature when the reversed coupling feature is introduced within the inner bore, so as to fixedly couple the anchorage member with the reversed articulating member, the first feature and the second feature being distinct from each other. The body is operable to be axially introduced into the glenoid before being coupled indifferently with one or the other of the anatomic and reversed articulating members.

An method includes creating a first bore and a second bore in a glenoid region of a scapula offset from each other by a first distance. A glenoid component is provided that includes a base component having a bearing surface and a first peg and a second peg each extending from a scapula-facing side of the base component and being positioned in non-parallel orientation with respect to each other. At least one of the first peg and the second peg is flexed so that a first end portion of the first peg and a second end portion of the second peg are offset by a second distance which corresponds to the first distance. The first end portion of the first peg and the second end portion of the second peg are then advanced into the first bore and the second bore, respectively.
