Glenoid vault fixation

Abstract

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.

         37 . A method for inserting a prosthesis into a shoulder for shoulder repair, comprising:
 preparing a bone for receiving an anchor;   positioning a superior-inferior component into the bone, the superior-inferior component comprises a body comprising a first bore, wherein the first bore comprises a seat, wherein the seat is shaped to receive the head of a screw, wherein the superior-inferior component comprises at least one superior-inferior component arm, wherein the first vertical component arm is integral to the body and extends from the body;   positioning an anterior-posterior component at least partially within the first bore of the superior-inferior component, the anterior-posterior component comprising a wall, wherein the wall defines an aperture, wherein the anterior-posterior component comprises a protruded portion distal to the wall, wherein the aperture extends into the protruded portion;   rotating the anterior-posterior component about the first bore to facilitate engagement with favorable bone; and   engaging a glenoid component within the aperture, wherein the glenoid component comprises a body, wherein the body comprises an articulating surface and a second surface opposite the articulating surf ace, wherein the second surf ace comprises a post that extends from the second surf ace, wherein when the glenoid component engages within the aperture, at least a portion of the post is contained within the aperture.   
     
     
         38 . The method of  claim 37 , wherein the at least one first superior-inferior component arm comprises two superior-inferior component arms, wherein each of the superior-inferior component arms further comprises a lateral bore separate from the central bore, wherein the method further comprises passing screws though each lateral bore; and securing the screws to the bone. 
     
     
         39 . The method of  claim 37 , wherein the anterior-posterior component further comprises at least one anterior-posterior component arm integral to the wall, wherein the at least one anterior-posterior component arm comprises a lateral hole separate from the central hole, wherein the method further comprises passing at least one screw through the at least one lateral hole; and securing the at least one screw to the bone. 
     
     
         40 . The method of  claim 37 , wherein when the anterior-posterior component is engaged with the superior-inferior component, the first bore is aligned with the first aperture, and the protruded portion is entirely contained within the bore, wherein the method further comprises inserting a screw through the aligned first bore and first aperture such that a head of the screw is captured by the seat; and securing the screw to the bone. 
     
     
         41 . The method of  claim 40 , further comprising attaching the articulating component to the anterior-posterior component by slidably locking the post within the aperture such that the head of the screw is lockably pressed against the seat. 
     
     
         42 . A method for inserting a prosthesis into a shoulder for shoulder repair, comprising:
 preparing a bone for receiving an anchor;   positioning a superior-inferior component into the bone, the superior-inferior component comprises a body comprising a first bore, wherein the superior-inferior component comprises a first superior-inferior component arm, wherein the first vertical component arm is integral to the body and extends from the body;   positioning an anterior-posterior component at least partially within the first bore of the superior-inferior component, the anterior-posterior component comprising a wall, wherein the wall defines an aperture;   rotating the anterior-posterior component about the first bore to facilitate engagement with favorable bone; and   engaging a glenosphere component within the aperture, wherein the glenosphere comprises a body and a metaglene component, wherein the metaglene component is received by a recessed portion on the body, wherein the metaglene comprises a post, wherein when the glenosphere component is engaged with the aperture, at least a portion of the post is contained within the aperture.   
     
     
         43 . The method of  claim 42 , wherein the at least one first superior-inferior component arm comprises two superior-inferior component arms, wherein each of the superior-inferior component arms further comprises a lateral bore separate from the central bore, wherein the method further comprises passing screws though each lateral bore; and securing the screws to the bone. 
     
     
         44 . The method of  claim 43 , wherein the anterior-posterior component further comprises at least one anterior-posterior component arm integral to the wall, wherein the at least one anterior-posterior component arm comprises a lateral hole separate from the central hole, wherein the method further comprises passing at least one screw through the at least one lateral hole; and securing the at least one screw to the bone. 
     
     
         45 . The method of  claim 44 , wherein when the anterior-posterior component is engaged with the superior-inferior component, the first bore is aligned with the first aperture, and the protruded portion is entirely contained within the bore, wherein the method further comprises inserting a screw through the aligned first bore and first aperture such that a head of the screw is captured by the seat; and securing the screw to the bone. 
     
     
         46 . The method of  claim 45 , further comprising attaching the glenosphere component to the anterior-posterior component by slidably locking the post within the aperture such that the head of the screw is lockably pressed against the seat. 
     
     
         47 . A method for replacing a glenoid that is engaged with a vertical component in the bone with a glenosphere, comprising:
 removing a glenoid that is engaged with an aperture in a vertical component that is inserted into bone;   preparing a glenosphere, wherein the glenosphere comprises a body, wherein the body comprises a proximal hole, wherein at least a portion of the proximal hole is threaded, and a metaglene component, wherein the metaglene component is received by a recessed portion on the body, wherein the metaglene comprises a post;   wherein preparing a glenosphere comprises inserting the metaglene into the recessed portion;   engaging the post of the metaglene in the aperture of the vertical component, wherein engaging the post in the aperture comprises at least partially inserting the post into the aperture; and   engaging a driving tool into the proximal hole and actuating the tool such that the glenosphere is pushed further into the aperture in the vertical component, wherein when the glenosphere is pushed further into the aperture, the glenosphere becomes lockably connected to the vertical component.
