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.

IPC: A61F2/40

Abstract: A humeral head assembly is provided that includes an articular body and a coupler. The articular body includes a coupling portion disposed on a side of the articular body opposite an articular surface. The coupling portion includes a continuous zone of eccentricity adjustment. The coupler portion optionally includes one or more than one discrete position site. The coupler includes a first portion and a second portion opposite the first portion. The first portion is configured to mate with the coupling portion and the second portion is configured to mate with another member of a joint prosthesis. A coupling portion with the continuous range of eccentricity adjustment can be provided on a bone anchor and the eccentricity of another component can be selected by motion of a coupler, such as a tray for reverse humeral assemblies, along the coupling portion of the anchor.

Abstract: Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.

Abstract: A prosthesis assembly including a base member that has a helical structure and one or more pathways. The helical structure extends between a first end and a second end. The pathway is accessible from the second end and is directed toward the first end 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 that has a support member and an arm that projects away from the support member. The arm is configured to be disposed in the pathway when the support member is disposed adjacent to the second 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.
