Abstract: In a bone cement mixing and delivery device, a plug can be removably disposable in an injection passage of a cylindrical container. A mixing screw can rotate in a chamber of the container and has a screw thread extending along an outer surface of the mixing screw as well as a return passage extending through the mixing screw from the proximal end to the distal end thereof. In a mixing mode of the device, a mixing rod engages and rotates the mixing screw about a longitudinal axis of the cylindrical container causing material disposed in the chamber to be moved distally and return to the proximal end of the chamber through the return passage of the mixing screw. In an injection mode of the device, the plug can be removed from the injection passage and an injection rod occludes the return passage of the mixing screw.

Abstract: Robotic systems 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 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. The virtual objects are located based on density data of the bone such that, when one or more shoulder implants are fully seated in the bone, distal portions of the implants are located in a first region of the bone having a density characteristic greater than an adjacent second region of the bone.
