Abstract:
A method and instrumentation for spinal interbody fusion is disclosed. The instruments and methods are particularly adapted for interbody fusion from a posterior approach to the spine. One instrument is a retractor having a lockable pivotally mounted handle. Another instrument is a template for straddling the dura. A modular distractor is also provided and preferably includes a tapered shaft with a visualization window disposed therein. Yet another instrument is a depth gauge to verify bone opening depth and dimension, preferably including a radiopaque portion. A method contemplates the use of these instruments to prepare a disc space to receive an implant.
