A method includes obtaining a model of a bone of a patient, identifying a plurality of landmarks of the model of the bone, defining a plane of the patient, determining an axis based on the plurality of landmarks and the plane, and planning a planned pose of an implant relative to the bone based on a relationship between a model of the implant, the axis, and the plane.

System and method for surgical planning

A method includes generating a surgical plan for installation of a structure at a bone and controlling a controllable guide structure to guide a cutting tool to sculpt the bone and the structure based on the surgical plan. Sculpting the bone provides the bone with a bone mating surface and sculpting the structure provides the structure with a structure mating surface. The method also includes installing the structure on the bone by engaging the structure mating surface of the structure with the bone mating surface of the bone.

System and method for preparing bone

A robotic system for preparing a bone to repair a bone fracture, includes a controllable guide structure configured to guide preparation of at least one bone piece during execution of a surgical plan and a control system configured to define the surgical plan. Defining the surgical plan includes determining a desired relationship between at least a first bone piece and a second bone piece that are separated by the bone fracture and planning preparation of the first bone piece to include a prepared anatomical structure configured to align the first bone piece with the second bone piece such that when aligned, the first bone piece and the second bone piece will achieve the desired relationship. The control system is further configured to control the controllable guide structure according to the surgical plan.

A memory device stores instructions, which, when executed by a controller, cause the controller to perform tasks. The tasks include obtaining a three-dimensional (3D) model of a patient's pelvis, identifying two landmarks of the 3D model of the patient's pelvis, defining a coronal radiographic plane of the patient, and determining a mediolateral axis of the 3D axis based on the two landmarks. The tasks also include planning the surgical placement of the acetabular cup into the acetabulum by positioning a virtual model of the acetabular cup relative to the 3D model and determining a planned version and a planned inclination based on the virtual model of the acetabular cup, the mediolateral axis and the coronal radiographic plane.

A system and method for determining inclination and version of a prosthetic acetabular cup relative to a coronal radiographic plane is provided. The system and method include the identification of a coronal radiographic plane in a three dimensional medical image. The system and method further include the identification of two symmetric landmarks on the pelvis to determine a mediolateral axis. The version and inclination can then be calculated based on the relationship between the axis of the acetabular cup, the coronal radiographic plan, and the mediolateral axis.

A robotic system for preparing a bone to receive a prosthetic device. The robotic system includes a controllable guide structure configured to guide cutting of the bone into a shape for receiving the prosthetic device, and a computer readable medium for storing data representative of the prosthetic device. The prosthetic device includes a body portion having an implantation surface configured to face the bone upon implantation and at least one feature that provides a constraint structure that will constrain the prosthetic device in the bone. The robotic system includes a control system for controlling the guide structure, and is configured to define at least one bone-cutting pattern for (i) removing a first portion of bone in a first area sufficient to seat the body portion and (ii) at least one of removing and maintaining a second portion of bone in a second area configured to interact with the constraint structure.
