Systems and methods for performing spinal surgery

Abstract

A revision instrument for positioning and securing an intervertebral implant in an intervertebral space between vertebrae is provided. The revision instrument includes a shaft having a body extending from a first end to a second end. A first port and a second port extend through the body of the shaft and a connection tool having a first end and second end is positioned within the first port. The connection tool extends through the first end of the shaft through the second end of the shaft. The first end of the connection tool includes a mating feature configured to couple with an expandable implant and the second end of the connection tool includes a rotation feature configured to rotate the connection tool to engage or disengage the connection tool with the expandable implant. The second port is configured to receive an expansion driver for expanding or compressing the expandable implant.

We claim: 
     
         1 . A revision instrument for positioning and securing an intervertebral implant in an intervertebral space between vertebrae, the revision instrument comprising:
 a shaft having a body extending from a first end to a second end;   a first port and a second port extending through the body of the shaft;   a connection tool having a first end and second end positioned within the first port, the connection tool extending through the first end of the shaft through the second end of the shaft;   wherein the first end of the connection tool includes a mating feature configured to couple with an expandable implant and the second end of the connection tool includes a rotation feature configured to rotate the connection tool to engage or disengage the connection tool with the expandable implant,   wherein the second port is configured to receive an expansion driver for expanding or compressing the expandable implant.   
     
     
         2 . The revision instrument of  claim 1 , wherein the mating feature of the connection tool is threaded features. 
     
     
         3 . The revision instrument of  claim 1 , wherein the mating feature of the connection tool is a dovetail connection. 
     
     
         4 . The revision instrument of  claim 1 , includes a third port for receiving an instrument to deliver graft material to the expandable implant. 
     
     
         5 . The revision instrument of  claim 1 , wherein the second port is configured to receive an instrument to deliver graft material to the expandable implant. 
     
     
         6 . The revision instrument of  claim 1 , wherein the revision instrument is secured to the expandable implant and removed only after positioning the pedicle screws within the pedicle of the spine. 
     
     
         7 . A spinal implant system for stabilizing adjacent vertebral bodies comprising:
 an expandable implant;   at least four pedicle screws, each at the at least four pedicle screws having a housing and configured to be positioned within the pedicle of the spine;   at least two rods configured to be positioned within the housing of the pedicle screws;   a revision instrument having a shaft having a body extending from a first end to a second end;   a first port and a second port extending through the body of the shaft;   a connection tool having a first end and second end positioned within the first port, the connection tool extending through the first end of the shaft through the second end of the shaft;   wherein the first end of the connection tool includes a mating feature configured to couple with an expandable implant and the second end of the connection tool includes a rotation feature configured to rotate the connection tool to engage or disengage the connection tool with the expandable implant,   wherein the second port is configured to receive an expansion driver for expanding or compressing the expandable implant.   
     
     
         8 . A revision instrument for positioning and securing an intervertebral implant in an intervertebral space between vertebrae, the revision instrument comprising:
 a shaft having a body extending from a first end to a second end;   a first port and a second port extending through the body of the shaft;   a connection tool having a first end and second end positioned within the first port, the connection tool extending through the first end of the shaft through the second end of the shaft;   wherein the first end of the connection tool includes a mating feature configured to couple with an expandable implant and the second end of the connection tool includes a rotation feature configured to rotate the connection tool to engage or disengage the connection tool with the expandable implant,   wherein the second port is configured to receive an expansion driver for expanding or compressing the expandable implant,   wherein expandable implant restores disc height and lordosis in the spine, and   wherein the revision instrument is positioned and retained to the expandable implant in a surgical site and secured to the skin to allow for a patient to be repositioned.
