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: A drive tool has a tubular drive shaft extending along a first axis with a first end of the shaft defining a connector element including a part-spherical cavity. A second end of the shaft has a drive element. The connector element has walls surrounding the part-spherical cavity, and a pair of slots extending along the walls of the connector element between an outer surface of the connector element and the cavity. A drive element extends along a second axis having a driver tool at a first end and a part-spherical head at a second end, the head pivotally mount in the part-spherical cavity in the connector element. A pair of deflectable arms which engage the part-spherical head are mounted adjacent the cavity of the tubular drive shaft and are deflectable through the slots onto the part-spherical head.

Abstract: A bone screw apparatus is provided for threaded engagement with a bone and, optionally, a medical device such as a bone plate. The bone screw has a shaft having a first end, a second end, and a first thread having a first pitch. The screw further includes a head having a proximal end, a distal end adjacent the shaft first end, and a second thread having a second pitch. The second thread has a variable pitch that increases in a proximal direction, but never exceeds the magnitude of any portion of the first pitch. Upon threaded engagement of the head with bone or a medical device, a compression force is generated which continuously decreases as the screw is further inserted.
