Abstract: One embodiment of the present disclosure relates to a glenoid implant with a body and a keel. The body includes an articulation surface and a bone facing surface, and the keel has a depth that extends from the bone facing surface to a free end of the keel. The keel has a first length and a first width, both measured in a plane perpendicular to a direction of the depth. The first length is measured perpendicular to the first width and is defined by a first distance from an inferior end of the keel to a superior end of the keel. The first width is measured at a first location adjacent to the inferior end, and the keel has a width dimension along a first portion of the keel from the first location to the superior end that tapers from the first location toward the superior end.

Abstract: A stemless prosthetic shoulder joint may include a prosthetic humeral head and a stemless base. The stemless base may include a collar and an anchor extending from the collar intended to anchor the base into the proximal humerus. The base may include a proximal collar having a proximal surface and a bone-engaging surface opposite the proximal surface. The collar may have a superior portion and an inferior portion, the superior portion defining an arc shape and the inferior portion defining a substantially triangular shape.

Abstract: A stemless prosthetic shoulder joint may include a prosthetic humeral head and a stemless base. The stemless base may include a collar and an anchor extending from the collar intended to anchor the base into the proximal humerus. The anchor may include various features to enhance the fixation of the base, including hooks, threads, and/or expandable members that may be transitioned from a contracted insertion condition to an expanded implanted condition once the base is positioned in the bone. The anchor and/or collar may also include additional features to enhance fixation, such as geometries and surface features to enhance fixation to bone. The anchor may include a plurality of chisel slots to facilitate removal of bone during a revision surgery.

Abstract: Disclosed herein is a humeral head and cup trials, a system for humeral trialing, and a method for removing a humeral head and cup trial from a humeral stem. The humeral trial may include a first portion, a second portion, and a post extending from the second portion. The first portion may define an articular surface. The post may define a first length in a first configuration and a second length in a second configuration. The first length may be greater than the second length. The post may change from the first configuration to the second configuration by moving the first portion with respect to the second portion.
