Abstract:
1. A shoulder prosthesis, comprising: a vault-filling component defining a bearing-facing surface and having a first coupling component, said vault-filling component including (i) a vault-filling first portion defining a first part of said bearing-facing surface, and (ii) a projecting second portion projecting from said vault-filling first portion so as to define a second part of said bearing-facing surface, said vault-filling first portion and said projecting second portion defining a bone space therebetween, a bearing component defining a bearing surface and having a second coupling component configured to cooperate with said first coupling component to couple said bearing component to said vault-filling component; a first externally threaded bone screw extending into said bone space; and a second externally threaded bone screw extending into in said bone space, wherein said projecting second portion of said vault-filling component further defines a scapula-facing surface, wherein said vault-filling first portion of said vault-filling component further defines (i) a first lateral surface extending from said scapula-facing surface, and (ii) a second lateral surface located opposite to said first lateral surface, and wherein said first lateral surface and at least a portion of said second lateral surface taper towards each other in a direction extending away from said bearing-facing surface, wherein (i) said vault-filling first portion includes a first internally threaded fastener passage extending therethrough, and (ii) said first externally threaded bone screw is meshingly received in said first internally threaded fastener passage, wherein (i) said projecting second portion includes a second internally threaded fastener passage extending therethrough, and (ii) said second externally threaded bone screw is meshingly received in said second internally threaded fastener passage, wherein said first internally threaded fastener passage extends from said first lateral surface to said second lateral surface, and wherein said second internally threaded fastener passage extends from said second part of said bearing-facing surface to said scapula-facing surface.
