Described herein are systems and methods for creating a custom registration guide. In general, the methods may include receiving scan data of a patient's bone; creating instructions based on the scan data for creating a three-dimensional surface model of the patient's bone; and moving a plurality of moveable elements, coupled to the adjustable model, based on the instructions. The method may further include the steps of placing a malleable registration guide onto the adjustable model and shaping the registration guide to fit to the adjustable model. The method may further include the step of intraoperatively determining the location of a patient's bone using the custom registration guide. The step of determining the location of the patient's bone may include the steps of coupling the registration guide and fiducial markers to the patient's bone.

An articulating drill system is provided that includes a hand-held portion and a drill portion. At least two actuators are provided for controlling at least two axes of the drill portion. A navigation system is provided to control the at least two actuators. In some embodiments, a tool is provided with the drill portion and adapted to interact with patient tissue. The drill portion can be modified to include at least two rigid objects in communication with the actuators and attached to the drill portion. The system can be used to make any linear cut within a deviation of 1.0 mm and 1.0?, or better in patient tissue.

A process for creating a curved contour on or within a bone is provided, where the process includes positioning a bone of a patient in a fixed position in a coordinate system, generating scan data of the bone, creating a three-dimensional surface model of the bone based on the scan data, generating a cutting program to modify a surface of the bone based on the three-dimensional surface model and a prosthesis having a bone interface shape that is complementary to the curved contour, and modifying the bone with one or more curved blades or a curved drill bit that is robotically driven and positioned with the cutting program to form the curved contour. A system for creating a curved congruent contour on or within a bone for mounting a prosthesis is also described.

A process and system for performing orthopaedic surgery with the use of computer systems and robotic assistance to remove bone, bone cement, and a bone prosthesis, typically a bone prosthesis used in hip replacement surgery, knee replacement surgery, and the like. The process for replacing one or more bone prostheses using a robotic system includes receiving image data comprising an image of each bone, including at least one prosthesis implanted within each bone; creating three-dimensional models of the prosthesis, and the bone; creating a plan for positioning new prostheses within the bone; determining the location and amount of bone and any non-bone material to be removed for the new prostheses; and removing the bone prosthesis from the bone. The inventive process may be used for the replacement of hip joints, shoulder joints, ankle joints, wrist joints, finger joints, toe joints, or other joints.

A process and system for performing orthopaedic surgery to create a series of channels with a subject's bone to allow a reduced pressure system to be applied directly to the bone-implant interface to enhance bone healing is provided. The process for to promote healing of a bone of a subject includes creating a three-dimensional model of the bone; preoperatively planning a location of an implant relative to the model; creating a plan for the location of precision channels that reach the bone-implant interface based on the model and the implant; resurfacing the bone to fit the implant into or onto the bone based on the preoperative plan; and milling the precision channels into the bone in the location to promote healing of the bone and/or bone implant interface; and applying a pressure reduction system at the bone-implant interface to promote bone healing.

Systems and methods for monitoring an operative site during a surgical procedure using a computer controlled surgical device. In general the methods include the steps of processing one or more defined cutting paths having one or more cut regions; determining a correlation between the cut region and one or more critical regions to generate an alert, wherein the alert indicates a movable end-effector is within a defined proximity of the critical region; and requiring a user acknowledgment of the alert to allow processing of the cutting path to continue. Also described herein are systems and methods for minimizing user fatigue during a semi-computer controlled surgical procedure. In general the methods includes the step of requiring a user generated acknowledgment in response to a computer generated alert, wherein the user acknowledgment is generated using a user controller, the user controller being minimally intrusive to the user experience.
