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.

Abstract: A method of repairing a fractured humerus may include implanting a prosthetic humeral stem into a humeral canal of the fractured humerus. First and second tuberosities of the fractured humerus may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the proximal end of the prosthetic humeral stem. The first and second tuberosities may be machined so that the first and second tuberosities have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the proximal end of the prosthetic humeral stem, and the first interlocking surface interlocks with the second interlocking surface.

Abstract: Robotic system and methods for preparing a bone of a joint to receive an implant. Virtual object(s) are used to define a volume of material to be removed from the bone for receipt of the implant. A robotic manipulator controls a cutting tool based on the virtual object(s) to form a first cavity and a second cavity in the bone. The second cavity is formed beneath the first cavity and is rotated relative to the first cavity to define an undercut in the bone. The first and second cavities receive a body and a locking member of the implant in an unlocked position. The locking member is rotated within the second cavity to a locked position whereby the undercut engages the locking member to limit withdrawal of the implant from the bone.

Abstract: Trials for a reverse shoulder system are described. The trials generally include an insert housed within a humeral cup. The insert has a proximal end and a distal end, the proximal end having a concave recess therein adapted to receive a glenosphere prosthesis. The distal end of the insert includes a shaft, the shaft is substantially housed within the confines of the humeral cup. A distal end of the humeral cup is inserted in a humeral stem.

Abstract: A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.

Abstract: Robotic system and methods for robotic arthroplasty. The robotic system includes a machining station and a guidance station. The guidance station tracks movement of various objects in the operating room, such as a surgical tool, a humerus of a patient, and a scapula of the patient. The guidance station tracks these objects for purposes of displaying their relative positions and orientations to the surgeon and, in some cases, for purposes of controlling movement of the surgical tool relative to virtual cutting boundaries or other virtual objects associated with the humerus and scapula to facilitate preparation of bone to receive a shoulder implant system.

Abstract: Disclosed herein are orthopedic revision systems including a base member having a collar portion and at least one stabilization portion extending outwardly from the collar portion. The systems may further include a stem member having an attachment portion and a shaft portion, the stem member configured to be received at least partially through an opening in the collar portion such that the attachment portion lies adjacent the collar portion and the shaft portion lies adjacent the at least one stabilizing portion. In a method of performing revision surgery with such orthopedic systems includes forming an opening in the collar of the base member for receipt of the stem member by removing an inner portion of the collar portion and inserting the stem member at least partially through the opening in the collar portion such that the attachment portion lies adjacent the collar portion and the shaft member lies adjacent the at least one stabilizing portion.
