SYSTEMS AND METHODS FOR BONE MODEL REGISTRATION WITH ADAPTIVE SOFT TISSUE THICKNESS

Abstract

Systems and methods for planning and assisting orthopaedic surgical procedures include a computing device and a robotic surgical device. The computing device defines a surgical coordinate system relative to a bone of a patient and captures a plurality of point positions in the surgical coordinate system. The plurality of point positions includes a first point position representing a location on a soft tissue surface covering a portion of the patient's bone. The computing device identifies an estimated soft tissue thickness value for each of the plurality of point positions and registers a three-dimensional model of the patient's bone in the surgical coordinate system based on the plurality of point positions and the estimated soft tissue thickness values. The computer system may control the robotic surgical device according to the registered bone model.
