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.

Stemless metaphyseal humeral implant

A fixation device for providing rotation stability to a femoral neck fracture. The device includes a bone plate having at least one opening, a compression screw housing extendable through the opening of the bone plate, a compression screw being at least partially disposed within the bore of the housing and selectively moveable through the bore, and a collapsible and expandable anchoring member coupled to the compression screw. The anchoring member is configured to transition between a collapsed condition and an expanded condition upon advancement of the anchoring member from the compression screw housing to rotationally stabilize the compression screw within a femur.
