Abstract

A method facilitates the treatment of the spine of a patient by providing simultaneous access through at least a first opening and a second opening formed in the patient. For example, the method can include the acts of positioning the patient on a surgical table, providing the first opening into a posterior portion of the patient, providing the second opening into a lateral portion of the patient, inserting a first device through the first opening into the patient to contact the spine in a first direction that is transverse to the coronal plane of the patient, and inserting a second device through the second opening into the patient to contact the spine in a second direction that is transverse to the sagittal plane of the patient, where the first and second openings are accessible simultaneously, and, when the first and second devises are inserted into the patient, the position of the patient is stationary with respect to a portion of the table.

Claims

1. A method for surgically treating the spine of a patient, the method comprising:

positioning a patient on a surgical table;

providing a first opening into a posterior portion of the patient;

providing a second opening into a lateral portion of the patient;

inserting a first device through the first opening into the patient to contact the spine in a first direction that is transverse to the coronal plane of the patient, the contact of the first device to the spine including fixed engagement of the first device to a first vertebral body;

inserting a second device through the second opening into the patient to contact the spine in a second direction that is transverse to the sagittal plane of the patient, the contact of the second device to the spine including fixed engagement of the second device to the first vertebral body; and

manipulating one of the first or second devices to move the first vertebral body relative to a second vertebral body;

wherein the first and second openings are accessible simultaneously, and wherein the one of the first or second devices is a manipulation instrument, and, when the first and second devices are inserted into the patient, the position of the patient is stationary with respect to a portion of the table.

2. The method of claim 1, wherein the first opening into the patient affords a substantially posterior approach to the spine, and the second opening into the patient affords a substantially lateral approach to the spine.

3. The method of claim 2, wherein the substantially posterior approach to the spine affords the first insertion direction to be substantially perpendicular to the coronal plane of the patient, and the substantially lateral approach to the spine affords the second insertion direction to be substantially perpendicular to the sagittal plane of the patient.

4. The method of claim 2, wherein the substantially posterior approach affords the first insertion direction to be from 45 degrees to −

45 degrees with respect to the sagittal plane, and the substantially lateral approach affords the second insertion direction to be from 45 degrees to −

45 degrees with respect to the coronal plane.

5. The method of claim 1, wherein the first direction is also at least partially transverse to the sagittal plane and the second direction is also at least partially transverse to the coronal plane.

6. The method of claim 1, further comprising inserting a third device that is a manipulation device through one of the first or second openings to engage the second vertebral body, manipulating the third device and the one of first or second devices to distract the first and second vertebral bodies apart from one another, and inserting a spinal implant between the first and second vertebral bodies.

7. A method for surgically treating the spine of a patient, the method comprising:

positioning a patient on a surgical table;

providing a first opening into a posterior portion of the patient;

providing a second opening into a lateral portion of the patient;

inserting a first bone screw through the first opening into the patient to contact the spine in a first direction that is transverse to the coronal plane of the patient, the contact of the first bone screw to the spine including fixed engagement to a first vertebral body;

inserting a second bone screw through the second opening into the patient to contact the spine in a second direction that is transverse to the sagittal lane of the patient, the contact of the second bone screw to the spine including fixed engagement to a first vertebral body;

engaging the first and second bone screws to one another within the first vertebral body; and

inserting a third bone screw through the first opening to fixedly engage the first vertebral body, and engaging the third bone screw to the second bone screw within the first vertebral body, wherein the first bone screw is inserted on one side of the spinous process of the first vertebral body, and wherein the third bone screw is inserted on the other side of the spinous process of the first vertebral body, and wherein the first and second openings are accessible simultaneously, and, when the first and second bone screws are inserted into the patient, the position of the patient is stationary with respect to a portion of the table.

8. A method for surgically treating the spine of a patient, the method comprising,

positioning a patient on a surgical table;

providing a first opening into a posterior portion of the patient;

providing a second opening into a lateral portion of the patient;

inserting a first bone screw through the first opening into the patient to contact the spine in a first direction that is transverse to the coronal plane of the patient, the contact of the first bone screw to the spine including fixed engagement to a first vertebral body; and

inserting a second bone screw through the second opening into the patient to contact the spine in a second direction that is transverse to the sagittal plane of the patient, the contact of the second bone screw to the spine including fixed engagement to the first vertebral body;

inserting a third bone screw through the first opening to fixedly engage the first vertebral body, wherein, after engagement of the first bone screw to the first vertebral body, a tip of the first bone screw is positioned one of above or below the second bone screw wherein, after engagement of the third bone screw to the first vertebral body, a tip of the third bone screw is positioned the other of above and below the second bone screw, and wherein the first and second openings are accessible simultaneously, and, when the first and second bone screws are inserted into the patient, the position of the patient is stationary with respect to a portion of the table.

9. The method of claim 8, wherein the first bone screw is inserted on one side of the spinous process of the first vertebral body, and wherein the third bone screw is inserted on the other side of the spinous process of the first vertebral body.

10. A method for surgically treating the spine of a patient, the method comprising:

positioning a patient on a surgical table;

providing a first opening into a posterior portion of the patient;

providing a second opening into a lateral portion of the patient;

inserting a first bone screw through the first opening into the patient to contact the s e in a first direction that is transverse to the coronal plane of the patient, the contact of the first bone screw to the spine including fixed engagement to a first vertebral body; and

inserting a spinal implant through the second opening into the patient to contact the spine in a second direction that that is transverse to the sagittal plane of the patient, the contact of the spinal implant to the spine including insertion thereof between the first vertebral body and a second vertebral body, the first vertebral body being positioned above the second vertebral body,

inserting a second bone screw through the first opening into the patient to contact the spine in a third direction that is transverse to the coronal plane of the patient, the contact of the second bone screw to the spine including fixed engagement to the second vertebral body wherein the third direction is at least in part in a caudal direction, wherein, after engagement of the first bone screw to the first vertebral body, a tip of the first bone screw is positioned one of anteriorly to the spinal implant, posteriorly to the spinal implant, or within a cavity of the spinal implant, and wherein, after engagement of the second bone screw to the second vertebral body, a tip of the second bone screw is positioned one of anteriorly to the spinal implant, posteriorly to the spinal implant, or within a cavity of the spinal implant, wherein the first and second openings are accessible simultaneously, and when the first bone screw and the spinal implant are inserted into the patient, the position of the patient is stationary with respect to a portion of the table.
