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 an implant with a suture passage and a method of attaching sutures to the same. The implant may include a suture pocket having a first pocket, a second pocket, and a suture hole disposed therebetween. The first pocket may have a first wall segment, the second pocket may have a second wall segment, and the suture hole may have a first sidewall segment extending from a first opening to a second opening. The first wall segment, the second wall segment, and the first sidewall segment may form a contiguous wall. A method of attaching a suture to the implant may include placing a tip of a suture needle on the first wall segment, sliding the suture needle into the first opening and pushing the suture needle through the suture hole.

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: 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.

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.
