An adjustable humeral implant comprising:
- a humeral tray having a humeral coupler receiving portion;
- and
- a humeral coupler having a humeral tray mating portion and a stem portion extending from the humeral tray mating portion along a first axis, the humeral tray mating portion translatable within the humeral coupler receiving portion in a direction transverse to the first axis.
An adjustable humeral implant comprising:
- a humeral coupler having a base and a stem extending from the base;
- and
- a humeral tray having a glenosphere-facing side and an opposed humerus-facing side, the humerus facing side including a recess at least partially defined by a bottom surface and opposed flanges, the recess configured to slidably receive the base of the humeral coupler such that the opposed flanges secure the base within the recess.
