Abstract
Described herein are devices and methods for fusion of adjacent vertebral bones using distractor platforms for exposure and resection of at least a portion of the facet joint, such as in performance of a TLiF procedure. In one embodiment, the distractor platform contains at least a first receptacle and/or extension adapted to couple to the implanted screw/bone marker and the method includes advancing a threaded segment of a bone fastener assembly into the identified first pedicle of the first vertebral bone, the first bone fastener assembly further comprises a second segment adapted to couple with a distraction platform adapted to concurrently attach onto at least one tissue retention blade and adapted to retain the tissue retention blade in the displaced position. Stabilization of a spinal segment is also provided by advancing a substantially concave orthopedic implant through an opening made in a posterior aspect of a disc space.
