Publication number: 20220354668Abstract: Robotic system and methods for preparing a bone of a joint to receive an implant. Virtual object(s) are used to define a volume of material to be removed from the bone for receipt of the implant. A robotic manipulator controls a cutting tool based on the virtual object(s) to form a first cavity and a second cavity in the bone. The second cavity is formed beneath the first cavity and is rotated relative to the first cavity to define an undercut in the bone. The first and second cavities receive a body and a locking member of the implant in an unlocked position. The locking member is rotated within the second cavity to a locked position whereby the undercut engages the locking member to limit withdrawal of the implant from the bone.Type: ApplicationFiled: July 27, 2022Publication date: November 10, 2022Applicant: Howmedica Osteonics Corp.Inventors: David Viscardi, Jan Heinsohn, Andrew Jacob Nelson, Rajan Yadav, Jetinder Singh
