Abstract

A spinal procedure includes attaching a first reduction instrument to a first guide assembly and a second guide assembly. The first reduction instrument includes a fixed attachment assembly and a translating attachment assembly that cooperatively interfaces the fixed attachment assembly. The first guide assembly is attached to a first pedicle and the second guide assembly is attached to a second pedicle. The first reduction instrument is moved to reduce an orientation of the spine, while imaging a reduction of the orientation of the spine. An angle and position of the first reduction instrument is locked upon achieving a desired reduction. The spine may then be fused.

Claims (27)

1. A spinal procedure, comprising:

attaching a first reduction instrument to a first guide assembly and a second guide assembly with the patient positioned in the lateral decubitus position, wherein the first reduction instrument comprises a handle, a body, and a translating attachment assembly, and wherein the handle and body are in a fixed relationship;

attaching the first guide assembly to a first pedicle;

attaching the second guide assembly to a second pedicle;

with the patient positioned in the lateral decubitus position, moving the first reduction instrument handle downward toward the spine causing the body to pivot around the translating assembly to reduce an orientation of the spine; and

following the reduction of the orientation of the spine, at least one of inserting an interbody implant into the spine and attaching a rod to the spine.

2. The procedure of claim 1 , wherein the reduction of the spine includes reducing a spondylolisthesis of the spine.

3. The procedure of claim 1 , further comprising inserting a plurality of pedicle screws into the spine prior to reduction of the orientation of the spine.

4. The procedure of claim 3 , further comprising using an oblique fluoroscopic view of the first and second pedicles while inserting the pedicle screws.

5. The procedure of claim 3 , further comprising using a bilateral fluoroscopic view of the first and second pedicles while inserting the pedicle screws.

6. The procedure of claim 1 , further comprising imaging a reduction of the orientation of the spine.

7. The procedure of claim 1 , further comprising using a second reduction instrument relative to one of the first guide assembly and the second guide assembly.

8. The procedure of claim 7 , wherein the first and second reduction instruments are different types of instruments.

9. The procedure of claim 7 , wherein the first and second reduction instruments are the same types of instruments.

10. A spinal procedure, comprising:

attaching a first reduction instrument to a pair of first guide assemblies while a patient is in a lateral decubitus position, wherein the first reduction instrument comprises a handle, a body, and a first translating attachment assembly, and wherein the handle and body are in a fixed relationship;

attaching a second reduction instrument to a pair of second guide assemblies while a patient is in a lateral decubitus position;

attaching the first guide assemblies to upside pedicles;

attaching the second guide assemblies to downside pedicles;

with the patient positioned in the lateral decubitus position, moving the first reduction instrument handle downward toward the spine causing the body to pivot around the first translating assembly to reduce an orientation of the spine;

locking an angle and position of the first reduction instrument upon achieving a desired reduction; and

following the desired reduction, at least one of inserting an interbody implant into the spine and attaching a rod to the spine.

11. The procedure of claim 10 , wherein the first reduction instrument includes a first fixed attachment assembly that cooperatively interfaces the first translating attachment assembly.

12. The procedure of claim 10 , wherein the second reduction instrument includes a second fixed attachment assembly and a second translating attachment assembly that cooperatively interfaces the second fixed attachment assembly.

13. The procedure of claim 10 , wherein the pair of the first guide assemblies are superior and inferior guide assemblies.

14. The procedure of claim 10 , wherein the first guide assemblies are attached to the upside pedicles before the second guide assemblies are attached to the downside pedicles.

15. The procedure of claim 10 , wherein the reduction of the orientation of the spine includes reducing a spondylolisthesis of the spine.
