Spinal implant system and method for lumbar and lumbosacral fusion

Abstract

A spinal implant comprises an implant body extending between an anterior surface and a posterior surface, and including a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least a first cavity and a second cavity. The cavities are oriented to implant fasteners in alignment with an oblique surgical pathway relative to a bilateral axis of a subject body and adjacent an anterior portion of an intervertebral space of the subject body. Systems and methods are disclosed.

         21 . A method for treating a spine, the method comprising:
 providing a surgical instrument comprising a first member, a second member and a third member;   sequentially disposing the members such that the first member engages tissue of a substantially posterior portion of an incision, the second member engages tissue of a substantially anterior portion of the incision relative and the third member engages tissue of a substantially cephalad portion of the incision; and   selectively orienting the members in a configuration to space the tissue.   
     
     
         22 . The method recited in  claim 21 , wherein the surgical instrument comprises a handle, the members each being connected to a handle, the first member extending along a first longitudinal axis, the second member extending along a second longitudinal axis. 
     
     
         23 . The method recited in  claim 22 , wherein the first member is connected to the handle by a pin. 
     
     
         24 . The method recited in  claim 23 , wherein the pin extends parallel to the first longitudinal axis. 
     
     
         25 . The method recited in  claim 22 , wherein the first member comprises a track having a first section and a second section. 
     
     
         26 . The method recited in  claim 25 , wherein the second section extends non-parallel relative to the first section. 
     
     
         27 . The method recited in  claim 25 , wherein the first member is connected to the handle by a pin, the pin being received in the second section. 
     
     
         28 . The method recited in  claim 27 , wherein the second section extends non-parallel relative to the first section. 
     
     
         29 . The method recited in  claim 22 , wherein the first member is connected to the handle by a pin, the pin extending parallel to the first longitudinal axis, the first member comprising a track having a first section and a second section, the second section extending non-parallel relative to the first section, the pin being received in the second section. 
     
     
         30 . The method recited in  claim 22 , wherein the first member is rotatable relative to the handle about the first longitudinal axis. 
     
     
         31 . The method recited in  claim 22 , wherein the second longitudinal axis extends parallel to the first longitudinal axis. 
     
     
         32 . The method recited in  claim 22 , wherein the second member is rotatable relative to the handle about the second longitudinal axis. 
     
     
         33 . The method recited in  claim 22 , wherein the first and second members are rotatable relative to one another about a pivot axis that extends parallel to the first and second longitudinal axes. 
     
     
         34 . The method recited in  claim 22 , wherein:
 the first member is rotatable relative to the handle about the first longitudinal axis;   the second longitudinal axis extends parallel to the first longitudinal axis; and   the second member is rotatable relative to the handle about the second longitudinal axis.   
     
     
         35 . The method recited in  claim 22 , wherein:
 the first member is rotatable relative to the handle about the first longitudinal axis;   the second member is rotatable relative to the handle about the second longitudinal axis; and   the first and second members are rotatable relative to one another about a pivot axis that extends parallel to the first and second longitudinal axes.   
     
     
         36 . The method recited in  claim 22 , wherein the handle includes arms that are independently connected with the first and second members to rotate the first and second members about a pivot axis. 
     
     
         37 . The method recited in  claim 22 , wherein the handle comprises first and second arms that are connected to the first and second members and a third arm that is connected to the third member, the third arm defining a slide axis, the third arm being configured to move in opposite directions along the slide axis to move the third member relative to the first and second members. 
     
     
         38 . The method recited in  claim 21 , wherein the members include an axial cavity and the method further comprises inserting a pin through each of the axial cavities and into bone to fix the members relative to the bone. 
     
     
         39 . A method for treating a spine, the method comprising:
 providing a surgical instrument comprising a handle, a first member, a second member and a third member, the members each being connected to a handle, the first member extending along a first longitudinal axis, the second member extending along a second longitudinal axis, the handle comprising first and second arms that are connected to the first and second members and a third arm that is connected to the third member, the third arm extending through the pivot axis, the third arm defining a slide axis that extends perpendicular to the pivot axis, the third arm extending through a ratcheting slide of the handle that is configured to prevent movement of the third arm along the slide axis;   sequentially disposing the members such that the first member engages tissue of a posterior portion of an incision, the second member engages tissue of an anterior portion of the incision and the third member engages tissue of a cephalad portion of the incision; and   selectively orienting the members in a configuration to space the tissue.   
     
     
         40 . A method for treating a spine, the method comprising:
