Abstract

Methods and instrumentation for surgical procedures relating to preparation of vertebral bodies and a disc space for insertion of spinal implants is disclosed. The instruments and methods are particularly adapted for a posterior approach to the spine. One instrument is a shim (10) having a blade (14) and a shaft (12) having a first end connected with the blade (14). The blade (14) is inserted into a distracted disc space to maintain distraction during subsequent procedures. In one embodiment, the shaft (12) can be bent away from the operative field. In another embodiment, the shim (10) is used in an endoscopically assisted approach to the spine. Another instrument is a driver for driving the blade (14) of the shim (10) into the distracted disc space. Various methods contemplate the use of these instruments to maintain disc space distraction during disc space preparation for receiving an implant.
