1. A base member of a stemless shoulder implant, the base member comprising:
a proximal collar having a main proximal surface and a bone-engaging surface opposite the proximal surface, wherein the proximal collar is annular and defines a continuously circular outer surface and a continuously circular inner surface;
an anchor extending distally from the bone-engaging surface of the collar;
a central opening in the proximal collar, the central opening having a taper, the central opening shaped and sized to receive a tapered connector of a prosthetic humeral head to lock the prosthetic humeral head to the base; and
an annular rim that defines a continuously circular outer surface that is positioned radially inward of the continuously circular inner surface of the proximal collar, the central opening being positioned radially inward of the continuously circular inner surface of the annular rim,
wherein a cylindrical recess is defined between the continuously circular inner surface of the proximal collar and the continuously circular outer surface of the annular rim,
wherein an entirety of the cylindrical recess has a depth extending distally of a distal-most surface of the bone-engaging surface of the proximal collar.
