Publication number: 20240108419Abstract: 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.Type: ApplicationFiled: December 13, 2023Publication date: April 4, 2024Applicant: MAKO Surgical Corp.Inventors: Scott David Nortman, Amit Mistry, Jason K.
