Abstract: A talar implant, comprising: a superior surface, defined by an arc having at least one first radius; an inferior surface, defined by an arc having at least one second radius, a lateral side; a medial side; a posterior portion having a first width; and an anterior portion having a second width; wherein the implant is configured to restore a tibio-talar joint tension, wherein the superior surface is separated from the inferior surface by a thickness, wherein the at least one first radius is smaller than the at least one second radius, wherein the center of the arc having at least one first radius is offset from the center of the arc having at least one second radius in at least one plane of the talar implant, and wherein the anterior portion further comprises an extension configured to provide support.

Abstract: Disclosed herein are components of a reverse shoulder prosthesis. In an embodiment, a reverse shoulder prosthesis includes a humeral adapter tray configured to sit near a resected surface of a humerus, the humeral adapter tray comprising: a cavity; a central bore; and a distal face including a boss, the boss: (i) configured as an extension of the distal face, (ii) posteriorly offset from the central bore by at least 10 mm, and (iii) configured to engage a humeral stem; and a humeral liner comprising: a distal rim configured to sit within the cavity of the humeral adapter tray; and a concave articulating surface configured to mate with a convex articulating surface of a glenosphere. In an embodiment, the boss, in addition to being posteriorly offset, is superiorly offset from the central bore by at least 8 mm. In an embodiment, the reverse shoulder a humeral stem which engages the boss.
