Glenoid augment and associated method
First Claim
1. An augmented glenoid implant assembly for cooperation with the glenoid fossa of a scapula, said implant assembly comprising:
- a first component for attachment to the scapula, said first component defining an support surface for cooperation with the glenoid fossa, a second surface positioned adjacent a buttress formed in the glenoid fossa and an assembly surface; and
a second component removably secured to said first component, said second component including an assembly face thereof, the assembly surface of said second component in close approximation to the assembly surface of said first component, said second component further comprising an articulating surface opposed to the assembly surface.

Abstract
A augmented glenoid implant assembly for use in performing shoulder arthroplasty is provided. The augmented glenoid implant assembly is used for cooperation with the glenoid fossa of a scapula. The implant assembly includes a first component for attachment to the scapula. The first component defines a support surface for cooperation with the glenoid fossa, a second surface positioned adjacent a buttress formed in the glenoid fossa and an assembly surface. The implant assembly also includes a second component removably secured to the first component. The second component includes an assembly face of the second component. The assembly surface of the second component is in close approximation to the assembly surface of the first component. The second component further includes an articulating surface opposed to the assembly surface.

26. A method of performing shoulder arthroplasty comprising the steps of:
-
forming a buttress-shaped recess in a portion of glenoid surface of a scapula;
providing a base glenoid component having a glenoid contacting surface configured to contact the portion of the glenoid surface of the scapula, a connecting surface spaced from the glenoid contacting surface, and a buttress surface for cooperation with the buttress-shaped recess;
securing said base glenoid component to the glenoid surface of the scapula such that the glenoid contacting surface is positioned in contact with the glenoid surface of the scapula, and the buttress surface is positioned against the buttress-shaped recess;
providing a bearing component removably secured to said base glenoid component, said bearing component including an assembly surface thereof and an opposed articulating surface configured to be contacted by the head portion of the humerus; and
securing said bearing component to said base glenoid component such that the articulating surface is positioned to be contacted by the head portion of the humerus and assembly surface of said bearing component is positioned against the connecting surface of said base glenoid component. - View Dependent Claims (27, 28, 29)
