    摘要: Methods and instrumentation for surgical procedures relating to preparation of vertebral bodies and a disc space for insertion of spinal implants is disclosed. One instrument is a shim having a blade and a shaft having a first end connected with the blade. The blade is inserted into a distracted disc space to maintain distraction during subsequent procedures. Another instrument is a driver for driving the blade of the shim 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.

    摘要: This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. The instruments include a distractor and a cutting instrument. In one embodiment the distractor includes a body portion and a pair of flanges extending along opposite sides of the body portion such that a slot is formed between the flanges and the body portion. The cutting instrument is positionable over the body portion and into the slots of the distractor so that the flanges are positioned between the cutting instrument and the adjacent tissue.
