An implant is disclosed that has a base member, an articulating member, and a coupling portion that secures the base member to the articulating member. The implant can be a shoulder implant (100, 200, 300) that has a baseplate (102, 230, 310), an articulating component (104, 210), and a fixation component (106, 270, 342). The baseplate includes a first side (110, 234, 314) with a projection (108, 240, 320) that has a first Morse taper and may be offset from a center line of the baseplate and a second side (116, 236, 316) that has a post or stem (114, 250, 330) that is offset from the center line of the baseplate. The articulating component includes a cavity (122, 220) with a second Morse taper that is offset from a center line of the articulating component. The articulating component is attachable to the baseplate when the projection is received in the cavity of the articulation component. A threaded through hole (130, 222) extends from the cavity of the articulating component to a second, convex side or articulating surface (120, 212) thereof. The through hole can be aligned with the cavity. The fixation component (106, 270, 342) can engage the through hole and is contained within a cavity (132, 322, 242) of the baseplate by a spring (138, 262, 360) and a cap (140), a second fixation member (280), or an engagement member (370).
