Abstract

Methods and instruments for preparing a disc space and for forming interbody devices therein are provided. The instruments include distractors having enlargeable portions positionable in the disc space for distracting the disc space. The enlargeable portions can also provide form about or against which an interbody device of a first material is placed. A second material may be placed in the disc space in the space previously occupied by the distractors.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a divisional of U.S. patent application Ser. No. 09 / 918,332, filed on Jul. 30, 2001, which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION [0002] The present invention relates generally to instruments and devices for spinal surgery, more particularly to methods and devices for spinal disc space preparation and interbody spinal stabilization. BACKGROUND OF THE INVENTION [0003] There are prior art interbody devices that are fabricated prior to implantation and then inserted into the patient's spinal disc space during surgery. It is also known to insert one or more pre-fabricated devices from anterior, antero-lateral, lateral, postero-lateral, transforaminal, posterior, posterior mid-line or any other known approach to the disc space. These pre-fabricated devices can require the surgeon to modify the interbody device, the vertebral bodies, and / or the vertebral endplates to achieve a desired fit...
