Abstract

Claims (27)

1 . A system comprising:

one or more computer readable storage devices configured to store a plurality of computer executable instructions; and

one or more hardware computer processors in communication with the one or more computer readable storage devices and configured to execute the plurality of computer executable instructions in order to cause the system to:

receive tracking data comprising position and/or orientation information of two or more vertebrae of a patient in substantially real time during a spinal surgery;

compare the received position and/or orientation of the two or more vertebrae with a predetermined surgical plan comprising desired position and orientation data of the two or more vertebrae, and generate an audible and/or visible alert when the position and/or orientation of the two or more vertebrae satisfies a predetermined threshold;

wherein the desired position and orientation data of the two or more vertebrae is based on:

one or more medical images of the patient,

a desired clinical outcome for the patient, and

data related to previous spinal surgeries of one or more other patients having the desired clinical outcome; and

generate guidance instructions for performing the spinal surgery based on the comparison of the received position and/or orientation of the two or more vertebrae with the predetermined surgical plan for the patient.

2 . The system of claim 1 , further comprising sensors attached to the two or more vertebrae of the patient, wherein the instructions that cause the system to receive the position and/or orientation information of the two or more vertebrae comprise instructions that cause the system to receive the position and/or orientation information from the sensors attached to the two or more vertebrae.

3 . The system of claim 2 , wherein the sensors are configured to be attached to the two or more vertebrae in a configuration such that two of three axes of position data to be collected by the sensors are on a plane assumed to be substantially parallel with a determinate angle to a sagittal plane of the patient.

4 . The system of claim 1 , wherein the instructions further cause the system to determine a desired curvature of a spine of the patient based on predicted post-operative parameters, the predicted post-operative parameters based on the data related to previous spinal surgeries of the one or more other patients.

5 . The system of claim 1 , wherein the one or more medical images of the patient comprise a pre-operative sagittal x-ray image of a spine of the patient.

6 . The system of claim 1 , wherein the instructions further cause the system to continuously generate guidance instructions for performing the spinal surgery until a spine of the patient is adjusted to a predetermined acceptable level.

7 . The system of claim 1 , wherein data related to previous spinal surgeries of the one or more other patients comprises data related to similar cases based on patient age, severity of deformation, or bone strength or density.

8 . The system of claim 1 , wherein the desired position and orientation data of the two or more vertebrae is further based at least in part on one or more preferences of a surgeon performing the spinal surgery for the patient.

9 . The system of claim 1 , wherein the desired position and orientation data of the two or more vertebrae is further based on modifying the accessed medical images to simulate an outcome of the spinal surgery for the patient.

10 . The system of claim 9 , wherein modifying the accessed medical images comprises simulating, on the one or more medical images, implantation of a spinal rod to a vertebral segment of interest.

11 . The system of claim 9 , wherein modifying the accessed medical images comprises partitioning at least one medical image into two or more portions and rotating at least one portion with respect to another portion to obtain a depiction of post-operative results or objectives.

12 . The system of claim 1 , wherein the desired position and orientation data of the two or more vertebrae is based on at least two of the one or more medical images of the patient after the at least two of the one or more medical images have been calibrated and scaled based on at least one common feature.

13 . The system of claim 1 , wherein the instructions further cause the system to display the position of the two or more vertebrae on a display based on the tracking data.

14 . The system of claim 1 , wherein the instructions further cause the system to generate a report comprising an overlay comprising at least two images of a spine of the patient, the at least two images obtained pre-operation, intra-operation, and/or post-operation.

15 . The system of claim 1 , wherein the instructions that cause the system to generate the guidance instructions comprise instructions that cause the system to recommend an implant dimension.

16 . The system of claim 15 , wherein the instructions that cause the system to recommend the implant dimension comprise instructions that cause the system to recommend the implant dimension based on a length of one or more ligaments determined from the one or more medical images.

17 . The system of claim 1 , wherein the predetermined surgical plan is based on a predictive model.

18 . The system of claim 1 , wherein the plurality of computer executable instructions that cause the system to receive the tracking data comprise computer executable instructions that cause the system to receive intraoperative fluoroscopy.
