Abstract

Methods are provided for planning, performing, and assessing of surgical correction to the spine during a spinal surgical procedure. These methods are implemented by a control unit through a GUI to digitize screw locations, digitize anatomical reference points, accept one or more correction inputs, and generate one or more rod solution outputs shaped to engage the screws at locations distinct from the originally digitized locations.

First claim

What is claimed is:

1 .- 20 . (canceled)

21 . A system for intraoperative planning and assessment of spinal deformity correction during a surgical spinal procedure, the system comprising:
an electronic computing device including:
a processing unit; and
memory, the memory including instructions that, when executed by the processing unit, cause the electronic computing device to:
receive location data for a plurality of surgical implants, wherein the surgical implants are screws;
based on the location data, display, on a user interface, an image of a spine including one or more points, each point corresponding to a respective location of a respective surgical implant of the plurality of surgical implants;
receive one or more correction inputs, via the user interface, including an adjustment to any one of (i) a position associated with the one or more points, (ii) an angle associated with the one or more points, or (iii) a combination of (i) and (ii);
display one or more adjusted points on the image based on the one or more correction inputs;
display, via the user interface, at least one rod solution shaped to engage the plurality of surgical implants at locations corresponding to the one or more adjusted points; and
generate bend instructions corresponding to the at least one rod solution.

22 . The system of claim 21 , further comprising:
a mechanical rod bender.

23 . The system of claim 21 , wherein the one or more correction inputs includes a correction in an axial plane and/or a correction in the coronal plane.

24 . The system of claim 21 , wherein the instructions, when executed by the processing unit, further cause the electronic computing device to:
generate a rotational deformity angle value based on the location data; and wherein the one or more correction inputs include an adjustment to the rotational deformity angle.

25 . The system of claim 21 , wherein the instructions, when executed by the processing unit, further cause the electronic computing device to:
generate a coronal Cobb angle based on the location data; and wherein the one or more correction inputs includes an adjustment to the coronal Cobb angle value.

26 . The system of claim 21 , wherein the instructions, when executed by the processing unit, further cause the electronic computing device to:
display, on the user interface, a best fit reference line on the user interface; and based on the one or more correction inputs, adjust the one or more points relative to the best fit reference line.

27 . The system of claim 21 , wherein the instructions, when executed by the processing unit, further cause the electronic computing device to:
display, on the user interface, a central sacral vertical line in a coronal plane; based on the one or more correction inputs, adjust the one or more points of the image of the spine relative to the central sacral vertical line in a coronal plane.

28 . The system of claim 21 , wherein the instructions, when executed by the processing unit, further cause the electronic computing device to: calculate a length of a rod that spans across all of the one or more adjusted points.

29 . The system of claim 21 , further comprising a vertically straight rod, a pre-bent rod, or a custom-bent rod.

30 . A system for intraoperative planning and assessment of spinal deformity correction during a surgical spinal procedure, the system comprising:
an electronic computing device including:
a processing unit; and
memory, the memory including instructions that, when executed by the processing unit, cause the electronic computing device to:
provide a user interface including:
a display of an image of a spine including one or more points, each point corresponding to a respective location of a respective surgical implant of a plurality of surgical implants;
one or more adjust-points controls configured to receive one or more correction inputs that adjust any one of (i) a position associated with the one or more points, (ii) an angle associated with the one or more points, or (iii) a combination of (i) and (ii), and cause a display of one or more adjusted points on the image, wherein the one or more adjusted points are generated based on the one or more correction inputs;
a calculate-rod button, that when selected, causes calculation of at least one rod solution shaped to engage the plurality of surgical implants at locations corresponding to the one or more adjusted points; and
a bend-instructions button, that when selected, causes generation of bend instructions corresponding to the at least one rod solution.

31 . The system of claim 30 , wherein the instructions, when executed by the processing unit, further cause the electronic computing device to:
display a best fit reference line on the image.

32 . The system of claim 31 , wherein the user interface further includes:
one or more coronal correction options configured to receive an amount of coronal correction.

33 . The system of claim 31 , wherein the one or more coronal correction options include:
a first coronal correction option selectable to increase a percentage of alignment of the adjusted points to the best fit reference line; and a second coronal correction option selectable to decrease the percentage of alignment of the adjusted points to the best fit reference line.

34 . The system of claim 30 , wherein the instructions, when executed by the processing unit, further cause the electronic computing device to:
display a central sacral vertical line in a coronal plane on the image.

35 . The system of claim 30 , wherein the user interface further includes:
a display of a rotational deformity angle or a coronal Cobb angle.

36 . The system of claim 30 , wherein the one or more correction inputs include adjustments in the sagittal plane.

37 . The system of claim 30 , wherein the instructions, when executed by the processing unit, further cause the electronic computing device to: calculate a length of a rod that spans across all of the one or more adjusted points.

38 . The system of claim 30 , wherein the at least one rod solution is for one of: a vertically straight rod, a pre-bent rod, and a custom-bent rod.

39 . A method for intraoperative planning and assessment of spinal deformity correction during a surgical spinal procedure, the method comprising:
causing an electronic computing device to:
receive location data for a plurality of surgical implants;
based on the location data, display, on a user interface, an image of a spine including one or more points, each point corresponding to a respective location of a respective surgical implant of the plurality of surgical implants;
receive one or more correction inputs, via the user interface, including an adjustment to any one of (i) a position associated with the one or more points, (ii) an angle associated with the one or more points, or (iii) a combination of (i) and (ii);
display one or more adjusted points on the image based on the one or more correction inputs;
display, via the user interface, at least one rod solution shaped to engage the plurality of surgical implants at locations corresponding to the one or more adjusted points; and
generate bend instructions corresponding to the at least one rod solution.

40 . The method of claim 39 , further comprising:
implanting the plurality of surgical implants; bending a rod according to the bend instructions; and implanting the rod.
