US Patent 7909871 Devices and methods for inter-vertebral orthopedic device placement

Disclosed are devices and methods for the placement of a bone fusion implant between vertebral bodies in a human or animal subject. In an exemplary method a pathway is formed in the first sacral vertebrae along a trajectory that has a starting point between the inferior aspect of the facet joint and the first posterior sacral foramen and transverses at least one pedicle, at least a portion of the first sacral vertebra and the disc space immediately superior to the sacrum. A fusion implant is placed into the formed pathway. Additional bone fasteners and inter-connecting rods are added to the fusion implant in order to further strengthen the construct. Embodiments that can be used to fuse an additional level are also disclosed.
