1. A reverse shoulder implant, comprising:
a baseplate configured to be secured to a glenoid of a scapular bone of a patient, the baseplate having a lateral end, a medial end, and a baseplate central channel extending through the baseplate from the lateral end to the medial end;
a central screw configured to at least partially pass through the central channel;
a locking nut having a cylindrical shape, an external thread on an outside surface of the locking nut and an internal thread on an internal surface of the locking nut, the locking nut configured to engage the central screw when the central screw and baseplate are implanted within the patient, wherein the external thread is configured to couple the locking nut with the baseplate central channel;
a glenosphere, having a lateral, convex articular surface, and a glenosphere central channel extending from the convex articular surface to an opposite side of the convex articular surface, wherein the glenosphere is configured to interface with the baseplate; and
a glenosphere screw, sized to pass at least partially within the glenosphere central channel and having external threads sized to secure the glenosphere screw to the internal thread on the internal surface of the locking nut to secure the glenosphere to the locking nut.
