Systems and methods for providing assistance to a surgeon during an implant surgery are disclosed. A method includes defining areas of interest in diagnostic data of a patient and defining a screw bone type based on the surgeon's input. Post defining the areas of interest, salient points are determined for the areas of interest. Successively, an XZ angle, an XY angle, and a position entry point for a screw are determined based on the salient points of the areas of interest. Successively, a maximum screw diameter and a length of the screw are determined based on the salient points. Thereafter, the screw is identified and suggested to the surgeon for usage during the implant surgery.

The present invention relates to a system and methods generally aimed at surgery. More particularly, the present invention is directed at a system and related methods for performing surgical procedures and assessments involving the use of neurophysiology.

The present invention concerns a method for obtaining an implantable plate for healing a fractured joint of a patient, comprising the steps of: 1) providing a 3D representation of a bone structure in a zone around a joint fracture, the zone comprising essentially all fragments of broken or ruptured bones and at least the ends of unbroken bones which form part of the fractured joint; 2) identifying different bone fragments within said 3D representation; 3) simulating a reduction of said bone fragments into a full joint; 4) calculating optimal parameter values for an implantable plate; 5) obtaining the implantable plate taking into account the calculated parameter values, whereby in step 3, the reduction is simulated by automatedly fitting positions and orientations of said bone fragments to a 3D representation of a healthy joint of said patient.

A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

A method of performing arthroplasty of an anatomical joint for receipt of an implant is disclosed. The method includes developing a preoperative plan, designing a patient specific guide based on the preoperative plan, obtaining the patient specific guide, placing the patient specific guide relative to the identified bone, fixing a pair of pins into the bone to establish an Alpha plane and executing the preoperative plan while referencing the Alpha plane. A desired amount of remaining first bone is determined based on a condition of the anatomical joint and a desired orientation of the implant. The patient specific guide includes a pair of bores defined therein and located in positions to accept a complementary pair of pins. The bores are arranged at locations on the patient specific guide to orient the respective pins in a direction optimized for surgeon access to the first bone and to establish the Alpha plane.

A computer assisted system is disclosed that includes an optical tracking system and one or more computing devices. The optical tracking system includes an RGB sensor and is configured to capture color images of an environment in the visible light spectrum and tracking images of fiducials in the environment in a near-infrared spectrum. The computer assisted system is configured to generate a color image of the environment using the color images, identify fiducial locations using the tracking images, generate depth maps from the color images, reconstruct three-dimensional surfaces of structures based on the depth maps, and output a display comprising the reconstructed three-dimensional surface and one or more surgical objects that are associated with the tracked fiducials. The computer assisted system can further include a monitor or a head-mounted display (HMD) configured to present augmented reality (AR) images during a procedure.
