摘要：
A shoulder prosthesis includes a vault-filling component defining a bearing-facing surface and having a first coupling component, the vault-filling component including (i) a vault-filling first portion defining a first part of the bearing-facing surface, and (ii) a projecting second portion projecting from the vault-filling first portion so as to define a second part of the bearing-facing surface. The vault-filling first portion and the projecting second portion define a bone space therebetween. The shoulder prosthesis further includes a bearing component defining a bearing surface and having a second coupling component configured to cooperate with the first coupling component to couple the bearing component to the vault-filling component. At least one bone attachment member positioned in the bone space. The projecting second portion of the vault-filling component further defines a scapula-facing surface. The vault-filling first portion of the vault-filling component further defines (i) a first lateral surface extending from the scapula-facing surface, and (ii) a second lateral surface extending from the first part of the bearing-facing surface. The first lateral surface and the second lateral surface taper towards each other in a direction extending away from the bearing-facing surface.
摘要（中）：
肩部假体包括限定支承面的表面并且具有第一联接部件的拱顶填充部件，所述拱顶填充部件包括（i）限定所述面向轴承表面的第一部分的拱顶填充第一部分和（ ii）突出的第二部分，其从所述拱顶填充第一部分伸出，以限定所述面向轴承表面的第二部分。 拱顶填充的第一部分和突出的第二部分在它们之间限定骨空间。 所述肩假体还包括限定支承表面的轴承部件，并具有构造成与所述第一联接部件配合以将所述轴承部件联接到所述拱顶填充部件的第二联接部件。 定位在骨空间中的至少一个骨附着构件。 拱顶填充部件的突出的第二部分进一步限定了朝向肩胛骨的表面。 拱顶填充部件的拱顶填充第一部分进一步限定（i）从面向肩胛骨的表面延伸的第一侧表面，和（ii）从所述支承面向表面的第一部分延伸的第二侧表面。 第一侧表面和第二侧表面在远离面向轴承表面的方向上朝向彼此逐渐变细。
