Abstract
An implant includes a fixed bearing, a floating bearing, and a coupling member. The fixed bearing defines a generally first spherical articulating surface and a stop. The floating bearing includes a second spherical articulating surface and a planar articulating bearing surface. The coupling member defines a bearing surface that translates relative to the planar articulating bearing surface.

An implant comprising:
- a fixed bearing defining a generally first spherical articulating surface and a stop;
- a floating bearing having a second spherical articulating surface and a planar articulating bearing surface;
- and
- a coupling member defining a bearing surface that translates relative to the planar articulating bearing surface.
An implant comprising:
- a stem;
- a coupling member supported by the stem and defining a first planar bearing surface;
- a fixed bearing defining a generally first spherical articulating surface and a stop;
- a floating bearing having a second spherical articulating surface and a second planar bearing surface, the second spherical articulating surface configured to mate with the first spherical articulating surface, the second planar bearing surface slidably coupled with the first planar bearing surface.
A method of assembling an implant comprising a stem, a fixed bearing having a first spherical articulating surface and a stop, a floating bearing having a second spherical articulating surface and a planar articulating bearing surface, and a coupling member having a bearing surface, the method comprising:
- securing the coupling member relative to a bone;
- securing the floating bearing to the coupling member by slidably coupling the planar articulating bearing surface relative to the bearing surface;
- mating the first spherical articulating surface to the second spherical articulating surface.
