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.

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.

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 orthopedic prosthesis includes a joint replacement portion that has a first side, a second side opposite the first side, and a screw hole that extends through the joint replacement portion from the first side and through the second side. The prosthesis also includes a peg that extends from the second side and that has a concave relief surface that partially defines the screw hole.

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.

The invention concerns a tibial prosthetic component comprising a plate (100) for forming a tibial plateau of a tibia (16), wherein a peripheral region of the plate (100) has a thickness of less than 3 mm. The invention also concerns a tibial prosthetic component having a keel of depth less than 9 mm. The invention also concerns a method of selecting a tibial prosthetic component comprising receiving measurements of at least one physical attribute of an individual into whom the tibial prosthetic component is to be implanted, selecting a thickness of a plate (100) and depth of keel of the tibial prosthetic component based on the measurements and providing a tibial prosthetic component comprising a plate (100) having the selected thickness and a keel having the selected depth. The invention may also comprise implanting a tibial prosthetic component selected in accordance with this method into an individual and a kit comprising a plurality of prosthetic components comprising plates having different thicknesses with keels of different depths.

One embodiment of the present disclosure relates to a glenoid implant with a body and a keel. The body includes an articulation surface and a bone facing surface, and the keel has a depth that extends from the bone facing surface to a free end of the keel. The keel has a first length and a first width, both measured in a plane perpendicular to a direction of the depth. The first length is measured perpendicular to the first width and is defined by a first distance from an inferior end of the keel to a superior end of the keel. The first width is measured at a first location adjacent to the inferior end, and the keel has a width dimension along a first portion of the keel from the first location to the superior end that tapers from the first location toward the superior end.

An acetabular prosthesis for use in a hip arthroplasty surgical procedure includes an acetabular cup cage assembly including an outer cup cage and an inner cup cage. The outer cup cage includes a hemispherical cup and a mounting flange. Similarly, the inner cup cage also includes a hemispherical cup and a corresponding mounting flange. The hemispherical cup of the inner cup cage is sized to be received into the hemispherical cup of the outer cup cage, and the two cup cages are rotatable relative to each other to position the mounting flanges into a desired position on a hip bone of a patient.
