APPARATUS AND METHOD FOR SPINAL FUSION USING POSTERIORLY IMPLANTED DEVICES
摘要
An apparatus and method for spinal interbody fusion is disclosed. This implant includes fasteners which firmly attach it to vertebrae adjacent to excised tissue so as to transmit tension and torsional loads to and from those vertebrae. The instruments and methods are particularly adapted for interbody fusion from a posterior approach to the spine. One instrument is a vertebral spreader that is able to create anterior lift to a fixed or variable angle. Another instrument is a tome for cutting rectangular grooves in bone and preparing end plate surfaces. A method contemplates the use of these instruments to prepare a disk space and the insertion of the implant.
