Abstract
Disclosed is a central augment. The central augment can include a body and a protrusion. The body can include a first curved surface shaped to interface with a central portion of a bone and a second surface opposite the first curved surface and defining a recess sized to receive a portion of a prosthetic component. The protrusion can extend from the second surface within the recess.

A glenoid prosthesis central augment for use in a shoulder replacement procedure, the central augment comprising:
- a body including a glenoid engagement surface having a continuous hemispherical shape to interface with a central portion of a reamed glenoid and a second surface opposite the glenoid engagement surface and defining a recess sized to receive a boss of a glenoid component;
- a protrusion extending from the second surface within the recess, the protrusion including an externally threaded surface operable to be received within a bore and engage an internally threaded surface defined by the boss of the glenoid component;
- and
- a post extending from the glenoid engagement surface, the post sized to be received in a bore formed in the central portion of the glenoid,
- wherein the body, the protrusion, and the post are monolithic,
- wherein at least one of the body and the post includes a porous metal coating.
