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.
Claims20
A central augment for use in a shoulder replacement procedure, the central augment comprising:
- a body including a glenoid engagement surface shaped to interface with a central portion of a reamed glenoid and a second surface opposite the first curved 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 sized to be received within a bore 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 at least one of the body and the post includes a porous metal coating.
The central augment of claim I ,wherein the first curved surface has a spherical shape.
A modular glenoid system for use in a shoulder replacement procedure, the modular glenoid system comprising:
- a glenoid component including:
- an articulation surface,
- a glenoid engaging surface opposite the articulation surface, and
- a boss extending from the glenoid engaging surface;
- and
- a modular augment including:
- a first outer surface,
- a second internal surface opposite the first outer surface and defining a recess sized to receive the boss.
- a post, the first outer surface forming a dome and shaped to interface with a reamed portion of a glenoid, the post extending from the first outer surface and sized to be received in a bore created in the glenoid;
- and
- a protrusion extending from the second internal surface and sized to be received within a bore in the boss.
A method for replacing a glenoid component, the method comprising:
- reaming a central portion of a glenoid;
- implanting a modular augment into the central portion of the glenoid, the modular augment including a first curved surface, a second curved surface opposite the first curved surface and defining a recess sized to receive a boss extending from an augment engaging surface of a glenoid component, the first curved surface including a post extending therefrom sized to be received in a bore created in the boss of the glenoid component;
- and
- implanting the glenoid component into the glenoid, the glenoid component coupled to the modular augment via the post and the bore created in the boss.
