Abstract
Systems and methods for planning and performing image free implant revision surgery are discussed. For example, a method for generating a revision plan can include collecting pre-defined parameters characterizing a target bone, generating a 3D model, collecting a plurality of surface points, and generating a reshaped 3D model. Generating the 3D model of the target bone can be based on a first portion of the pre-defined parameters. Generating the reshaped 3D model can be done based on the plurality of surface points collected from a portion of the surface of the target bone.
Claims19
A method for conducting a revision surgical procedure, the method comprising:
- removing an existing implant from a target bone;
- removing a deteriorated portion from the target bone, to form a modified target bone;
- reinserting the existing implant onto the modified target bone;
- tracking a trackable surgical instrument to collect three-dimensional surface data of the modified target bone with the existing implant reinserted onto the modified target bone;
- generating a virtual three-dimensional model of the modified target bone based on the surface data;
- removing the existing implant from the modified target bone;
- preparing the modified target bone to receive a revision implant based on the virtual three-dimensional model;
- and
- affixing the revision implant into the modified target bone.
A system for conducting a revision surgical procedure, the system comprising:
- a first surgical instrument configured to remove an existing implant from a target bone;
- a second surgical instrument configured to remove a deteriorated portion from the target bone, generating a modified target bone;
- a trackable surgical instrument configured to collect three-dimensional surface data of the modified target bone with the existing implant reinserted onto the modified target bone;
- and
- a control system comprising a communication interface and at least one processor coupled to a memory device, wherein the control system is coupled to the tracking system and is configured to:
- generate a virtual three-dimensional model of the modified target bone based on the surface data,
- navigate preparation of the modified target bone for receiving a revision implant based on the virtual three-dimensional model, and
- navigate affixation of the revision implant into the modified target bone.
