Abstract:
A stemless prosthetic shoulder joint may include a prosthetic humeral head and a stemless base. The stemless base may include a collar and an anchor extending from the collar intended to anchor the base into the proximal humerus. The anchor may include various features to enhance the fixation of the base, including hooks, threads, and/or expandable members that may be transitioned from a contracted insertion condition to an expanded implanted condition once the base is positioned in the bone. The anchor and/or collar may also include additional features to enhance fixation, such as geometries and surface features to enhance fixation to bone. The anchor may include a plurality of chisel slots to facilitate removal of bone during a revision surgery.

Claim (Index 1):
A base member of a stemless shoulder implant, the base member comprising:\n a proximal collar having a proximal surface, a bone-engaging surface, and a plurality of holes extending from the proximal surface to the bone-engaging surface, wherein each of the plurality of holes is adapted to receive a non-integral fixation member; a central anchor extending distally along a longitudinal axis of the base member from the bone-engaging surface of the collar a first distance to a central tip and having a plurality of flutes extending toward the central tip; and one or more integral peripheral anchors each positioned radially outwardly of the central anchor and extending distally from the bone-engaging surface of the collar a second distance to a peripheral tip, the first distance being greater than the second distance, the one or more integral peripheral anchor being integral with the base member, the non-integral fixation member being non-integral with the base member.
