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 shoulder prosthesis system, comprising:
an elongated superior-inferior (SI) component, wherein the superior inferior component comprises a body comprising a first bore, wherein the first bore extends at least partially through the body, wherein the superior inferior component comprises first and second superior-inferior component arms, wherein the first and second superior inferior component arms are integral to the body and extend from the body, wherein the first and second superior-inferior component arms are straight and coplanar to each other and at least one of the first and second superior-inferior component arms comprise an opening extending from the arm, the opening defined by a wall and transverse to the arms; an elongated anterior-posterior (AP) component, wherein the anterior-posterior component comprises a wall defining an aperture, a protruded portion distal to the wall, wherein the aperture comprises a central axis and at least partially extends into the protruded portion, wherein the superior-inferior component engages the anterior-posterior component, wherein the first bore of the superior-inferior component is shaped to receive a portion of the protruded portion of the anterior-posterior component; at least one anchor; and an articulating component, wherein the articulating component comprises an articulating surface, a second surface opposite the articulating surface, and a post, wherein the post extends from the second surface, wherein the articulating component at least indirectly engages the superior-inferior component, wherein the bore of the superior-inferior component is shaped to receive a portion of the post, wherein the superior-inferior and anterior-posterior components form a bone-engaging cruciate structure when they are engaged.
