Claim 10:
11. A method of positioning a spinal implant into an intervertebral space of a subject, comprising:
positioning the subject in a right lateral decubitus position;
creating an anterolateral incision;
establishing an oblique retroperitoneal operative corridor in the subject extending from the anterolateral incision to a location proximate an anterolateral portion of the intervertebral space, wherein establishing the oblique retroperitoneal operative corridor comprises:
inserting a first retractor blade lateralizing a left common iliac vein and a left common iliac artery, and inserting a second retractor blade lateralizing a right common iliac vein and a right common iliac artery;
advancing the spinal implant along the oblique retroperitoneal operative corridor to the intervertebral space, wherein the spinal implant is configured to pivot relative to an insertion tool during said advancing and further comprises:
an implant body having an internally threaded pivot element slidably mounted within the implant body;
a top bearing face having upper bone engagement protuberances;
a bottom bearing face having lower bone engagement protuberances;
an anterior face having a front maximum height;
a posterior face having a rear maximum height less than the front maximum height of the anterior face;
an ipsilateral face extending between the top bearing face and the bottom bearing face;
a contralateral face;
an internal divider wall that at least partially defines a first tissue ingrowth window extending through the top and bottom bearing surfaces, the first tissue ingrowth window being positioned between the contralateral face and the internal divider wall; and
a recessed slot in the ipsilateral face to provide access under the top bearing face and above the bottom bearing face to a threaded opening of the internally threaded pivot element slidably mounted within the implant body, the threaded opening of the internally threaded pivot element defining a central axis that is adjustable relative to the implant body in response to slidable movement of the internally threaded pivot element relative to the recessed slot in the ipsilateral face; and

pivoting the implant body while at least a portion of the spinal implant is positioned within the intervertebral space to move the implant body from an initial diagonal orientation to a medial-lateral orientation generally symmetric with respect to a vertebral column axis.
