Glenoid vault fixation

摘要

A joint prosthesis system, specifically a shoulder prosthesis, for shoulder replacement, revision and repair. The implants provide fixation into the best bone available to a surgeon. The implants are used in a superior-inferior and anterior-posterior construct forming a type of cross or X-shape. The implants allow for interchangeability of the articulating component as well as rotational orientation. The systems will allow for augments to accommodate bone loss. The implants may allow for additional security using screws or anchors inserted into the scapula.

主权项

1. A joint prosthesis configured to couple to one of an articulating component and a glenosphere, each of the articulating component and the glenosphere including a post, the post including at least one of a protrusive ring and a cutout ring, the joint prosthesis comprising:
a vertical component, wherein the vertical component comprises a body comprising a bore extending at least partially through the body in a longitudinal direction and at least one vertical component arm extending from the body; and a horizontal component, wherein the horizontal component comprises a wall defining a hole, an engagement ring positioned on the wall, the engagement ring extending at least one of toward a center of the hole and away from the center of the hole, the engagement ring being configured to engage the at least one of the protrusive ring and the cutout ring on the post of the one of the articulating component and the glenosphere, and at least one horizontal component arm extending from the wall; wherein the vertical component and the horizontal component are configured to engage at the body of the vertical component and the wall of the hole of the horizontal component.
