Abstract

Claims (38)

1. A surgical method, comprising:

attaching a first sensor to a first vertebra of a spine of a patient;

attaching a second sensor to a second vertebra of the spine of the patient;

detecting and transmitting position information using a first processor of the first sensor and a second processor of the second sensor in real-time;

performing an angular correction of the spine along one or more of the axial, coronal, or the sagittal planes to achieve segmental or global plane alignment;

using a third processor, continually calculating an angular orientation of the first and second sensors throughout the angular correction; and

displaying a real-time, quantitative measurement of angular correction of the spine throughout the angular correction.

2. The method of claim 1 , further comprising measuring segmental or global plane alignment of the spine.

3. The method of claim 1 , wherein detecting position information is performed without intraoperative imaging.

4. The method of claim 1 , further comprising preoperatively determining a desired spinal correction associated with the patient, the desired spinal correction including a desired correction angle.

5. The method of claim 4 , further comprising stabilizing the spine when angular correction of the spine aligns with the desired correction angle.

6. The method of claim 1 , further comprising one or more of the first sensor or the second sensor communicating its position to the other sensor.

7. The method of claim 6 , further comprising, using the third processor, calculating a relative angle of the first sensor with respect to the second sensor in the sagittal plane.

8. The method of claim 7 , further comprising attaching an additional sensor to one or more of a third vertebra or a surgical instrument, the additional sensor calculating different positional information from the first sensor and the second sensor.

9. The method of claim 8 , further comprising displaying a first set of information on the first and second sensors while displaying a second set of information on the third sensor.

10. The method of claim 9 , wherein the first set of information comprises orientation information and the second set of information comprises orientation and position information.

11. The method of claim 1 , wherein the angular correction is performed along the sagittal plane.

12. The method of claim 1 , wherein displaying the real-time, quantitative measurement of angular correction comprises a color-coded visual indication.

13. A surgical method comprising:

attaching a first sensor to a first vertebra;

attaching a second sensor to a second vertebra;

detecting and transmitting position information using a first processor of the first sensor and a second processor of the second sensor in real-time;

adjusting a position of the first vertebra with respect to the second vertebra; and

using a third processor, determining and graphically displaying an angle related to relative positions of the first vertebra and the second vertebra based on real-time quantitative intraoperative assessment of data from the first sensor and the second sensor.

14. The method of claim 13 , wherein determining the surgically-corrected angle further comprises calculating the surgically-corrected angle based on data from the first sensor and the second sensor.

15. The method of claim 14 , wherein the surgically-corrected angle is calculated continually throughout changes in orientation of the surgically-corrected angle.

16. The method of claim 13 , wherein the first sensor and the second sensor are configured to graphically display the surgically-corrected angle.

17. The method of claim 13 , further comprising preoperatively determining a desired spinal correction associated with a patient, the desired spinal correction including a desired correction angle.

18. The method of claim 17 , further comprising using the third processor, providing feedback regarding the surgically-corrected angle relative to the desired correction angle.

19. The method of claim 18 , wherein the feedback includes a color-coded visual indication.

20. A surgical method, comprising:

attaching a first sensor of a plurality of sensors to a first vertebra of a spine of a patient;

attaching a second sensor of the plurality of sensors to a second vertebra of the spine of the patient;

monitoring positions of each of the first vertebra and the second vertebra in real-time using the plurality of sensors coupled thereto;

performing angular correction of the spine along one or more of the axial, coronal, or the sagittal planes to achieve segmental or global plane alignment;

using a processor, continually detecting an angular orientation of the first and second sensors throughout the angular correction; and

displaying a real-time, quantitative measurement of angular correction of the spine throughout the angular correction,

wherein displaying the real-time, quantitative measurement of angular correction comprises a color-coded visual indication.
