1. An instrument guide for implanting a spinal implant between opposing vertebral bodies, the instrument guide comprising:
- a first member including a first proximal region having a tubular configuration and a first distal region having a first lateral guide surface, the first lateral guide surface having a first distal end;
a second member having a second proximal region including a tubular configuration and a second distal region having a second lateral guide surface, the second lateral guide surface having a second distal end;
the second member being fixed adjacent and parallel to the first member.

Abstract
The present invention provides instruments and methods for insertion of spinal implants into the intervertebral space between opposing vertebral bodies. Instrumentation according to the invention includes an instrument guide having a first member and a second member each having a tubular proximal region and a distal region having a lateral guide surface. The instruments and methods of the invention are particularly advantageous for placement of spinal implants using a posterior approach to the vertebrae.
