Abstract
This invention relates to devices and instruments for implant insertion through a posterior lateral opening to the disc space. The instruments include an implant inserter, and the devices include a spinal fusion implant engageable by the implant inserter. The implant provides bilateral support of the adjacent vertebrae when inserted into the disc space from a postero-lateral approach.
Claims20
A method for inserting an implant in a spinal disc space, comprising:
- creating an oblique opening into the disc space;
- providing an implant for insertion into the disc space;
- positioning a leading end of the implant at the opening;
- and
- alternatively applying pushing and pivoting forces to the implant to position the implant through the opening and in the disc space along a non-linear insertion path,
- wherein applying the pushing and pivoting forces comprises contacting the implant with at least one instrument positioned through the opening and pivoting and pushing the implant with the at least one instrument.
