    Abstract: A stemless humeral anchor (10) includes a first end (12) configured to be embedded in a proximal portion of a humerus and a second end (14); a mating portion (16) for an articular component; a transversely extending collar (20); and a rotation control feature (22, 22A) for resisting rotation when the stemless humeral anchor is implanted. A void filling protrusion (24) can extend circumferentially from rotation control feature and can include a porous shell (26), in which a void filling component (28) can be disposed. The rotation control feature can comprise arms. One or more arms (22A) can have a larger radial extent than the others (22). A prosthesis assembly includes a base member (104) that has a helical structure (224) and one or more pathways (300). The pathway is accessible from a proximal end and is directed distally through the helical structure. The pathway is located inward of an outer periphery of the helical structure. The pathway extends in a space between successive portions of the helical structure. The prosthesis assembly includes a locking device (108) that has a support member (132) and an arm (110) that projects away from the support member. The arm is disposed in the pathway when the support member is disposed adjacent to the proximal end of the base member. The arm is disposed through bone in the space between successive portions of the helical structure when the prosthesis assembly is implanted.

    Abstract: Provided is a method of assembling an articular component of a prosthetic shoulder joint. The method includes: engaging an end of a coupler of a joint implant with a coupling portion of another component of the joint implant; providing relative rotation between the end of the coupler and the coupling portion of the other component of the joint implant along a continuous range of rotational positions while the end is engaged with the coupling portion of the other component of the joint implant; selecting an amount of eccentricity corresponding to a position within the continuous range of rotational position; and securing the other component of the joint implant to the end of the coupler at the selected amount of eccentricity.

    Abstract: A stemless humeral shoulder assembly having a base member and an anchor advanceable into the base member. The base member can include a distal end that can be embedded in bone and a proximal end that can be disposed at a bone surface. The base member can also have a plurality of spaced apart arms projecting from the proximal end to the distal end. The anchor can project circumferentially into the arms and into a space between the arms. When the anchor is advanced into the base member, the anchor can be exposed between the arms. A recess can project distally from a proximal end of the anchor to within the base member. The recess can receive a mounting member of an anatomical or reverse joint interface.
