Claims22
A method for fixation of a sacrum with at least an immediately superior vertebral bone, comprising:
- creating a first borehole into an anterior cortical bone surface of said sacrum;
- advancing a first fixation post through said first borehole, said sacrum, and a disc space immediately superior to said sacrum, and into said immediately superior vertebral bone;
- creating a second borehole in said anterior cortical bone surface of said sacrum, said second borehole being different than said first borehole;
- advancing a second fixation post through said second bore hole, said sacrum, and said disc space, and into said immediately superior vertebral bone;
- and
- connecting a proximal aspect of said first fixation post with a proximal aspect of said second fixation post, said connected proximal aspects of each of said first and second fixation posts configured to be positioned at least partially outside of said anterior cortical bone surface of said sacrum.

A method for fixation of a sacral bone with at least one superior vertebral bone, comprising:
- advancing a first fixation member through a pedicle portion of said superior vertebral bone from a posterior to an anterior trajectory, a distal end of said first fixation member being positioned within a body of said superior vertebral bone;
- creating a borehole in an anterior cortical bone surface of said sacral bone;
- advancing a second fixation member through said borehole, through said sacral bone, a disc space immediately superior to said sacral bone, and into said superior vertebral bone;
- and
- affixing a distal segment of said first fixation member with a distal segment of said second fixation member within said superior vertebral bone.
