Abstract: A method to guide in preparation of a bone relies on an instrument having a shaft with a working end and a stop member. The shaft is free to translate along an axis. Surgical planning data is registered to the bone to determine intra-operative coordinates of the desired axis and depth. The instrument holder is positioned by the bone so the stop member contacts the instrument holder to prevent translating beyond the desired depth. Alternatively, an arm is manipulated to align the instrument with the desired axis. The working end rests on the bone to define a linear separation to the desired depth. By proximally translating the instrument holder to contact the stop member and distally translating the instrument holder along the shaft, the stop member physically stops translating beyond the desired depth. A surgical system for performing the methods is provided; a reamer or impactor are also disclosed.

Abstract: Systems and methods for creating planar cuts on a bone are provided utilizing one or more cutting guides assembled to a plurality of bone pins, where the bone pins are inserted on the bone coincident with one or more virtual pin planes defined relative to one or more of the planar cuts. Alignment guides are also disclosed herein that aid in the creation of pilot holes for receiving a cutting block in a desired position and orientation (POSE). An articulating surgical device actively positions the bone pins coincident with the virtual plane to ensure the cutting guides, when assembled to the pins, aligns one or more guide slots in the desired POSE to create the planar cuts.

Abstract: A system and method are described herein for creating planar bone cuts on a bone to receive a total knee arthroplasty (TKA) femoral implant. The system includes a robotic surgical device, a computing system, and one or more contingent manual instruments. A surgical plan is generated having instructions for the robotic surgical device to create six or more planar bone cuts on the bone. The robotic surgical device executes the instructions, and in the event the robotic procedure is aborted before completing the six or more planar cuts, the one or more contingent manual instruments are used to create any remaining planar bone cuts. The one or more contingent manual instruments may include a plurality of uniquely arranged guide slots to assist a user in creating one or more remaining planar bone cuts.

Abstract: A method for registering a bone is provided that includes the installation of two or more registration markers on an exposed portion of the bone as part of a first stage of a revision. An image data set of the bone is generated to create imaged registration markers. A surgical plan is generated for implanting one or more secondary implants in a second stage of the two-stage procedure based on the image data. The bone is registered to the surgical plan and a computer-assist device using the two or more registration markers by: digitizing a set of positions of the two or more registration markers to create digitized registration markers; and mapping the set of positions of the digitized registration markers with a corresponding set of positions of the imaged registration markers.

The location of the harvest region is registered to a first computer-assist device and the bone graft is harvested. The target region is registered to the first computer-assist device or another device. The cutting characteristics for the target region are communicated to the first computer-assist device or the other device to receive the bone graft.
