Adjustable orthopedic connections

A humeral implant comprising:

• an articulating member including a first side defining a bore and a second side defining an articulating surface;
• a fixation member anchorable to a humerus of a patient;
• a quasi-spherical member including a textured outer surface, the quasi-spherical member configured to be at least partially received in the bore of the articulating member in a plurality of different angular orientations relative to an axis of the bore;
• and
• a connecting member including a first end coupled to the fixation member and a second end coupled to the quasi-spherical member;
• wherein portions of the textured outer surface of the quasi-spherical member are deformable upon forcible contact with a wall of the bore for fixing the position of the quasi-spherical member relative to the position of the articulating member in each of the different angular orientations;
• and
• wherein the textured outer surface includes at least one of a plurality of generally planar faces, a plurality of surface elements with polygonal perimeters, or a three-dimensional tessellation incorporating polygonal surfaces.

A humeral implant comprising:

• an articulating member including a tapered bore;
• a fixation member anchorable to a humerus of a patient, the fixation member including a plurality of fixation fins extending from an inferior side thereof;
• a quasi-spherical member including a textured outer surface, the quasi-spherical member configured to be at least partially received in the tapered bore of the articulating member in a plurality of different angular orientations relative to an axis of the tapered bore;
• and
• a connecting member extending between a superior side of the fixation member and the quasi-spherical member;
• wherein portions of the textured outer surface of the quasi-spherical member are deformable upon forcible contact with a wall of the tapered bore for fixing the position of the quasi-spherical member relative to the position of the articulating member in each of the different angular orientations.
