Abstract
A system for augmenting a glenoid in preparation for implantation of a glenoid implant includes an augment guide block. The augment guide block includes a body having a guide slot angularly extending from a first surface to a second surface at an angle α, a plurality of alignment members extending from the first surface of the body that couple the body to the glenoid at locations that correspond to locations where a central peg and a peripheral peg will couple the glenoid implant to the glenoid. The system also includes an augmenting device that is configured to be received within the slot, and that is operable to augment the glenoid at the angle α, wherein the angle α corresponds to a surface of the glenoid implant.
Claims17
A guide device for augmenting an anatomic structure, comprising:
- a body including an upper surface, a lower surface, and a peripheral surface that connects each of the upper and lower surfaces;
- a guide slot extending between the upper surface and the lower surface of the body at an angle α that is non-parallel and non-perpendicular relative to the upper and lower surfaces, the guide slot configured for receipt of a shaping device that shapes the anatomic structure at the angle α;
- and
- a plurality of alignment members extending from the lower surface that are configured to removably couple the body to the anatomic structure, the alignment members extending from the lower surface at an angle that is different from angle α when viewed in a common plane.
A system for augmenting a glenoid in preparation for implantation of a glenoid implant including a central peg and a peripheral peg, comprising:
- an augment guide block, the augment guide block including a body having a guide slot angularly extending from a first surface to a second opposing surface at an angle α, a plurality of alignment members extending from the first surface of the body that are configured to removably couple the body to the glenoid at locations that correspond to locations where the central peg and peripheral peg will couple the glenoid implant to the glenoid, and a boss formed on the second surface, wherein the alignment members extend from the first surface at an angle that is different from angle α when viewed in a common plane;
- a handle configured to mate with the boss, and operable to orient the augment guide block relative to the glenoid;
- and
- an augmenting device configured to be received within the slot, and operable to augment the glenoid at the angle α, wherein the angle α corresponds to a surface of the glenoid implant.
