    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: A guide assembly for positioning one or more bone engaging fasteners in a bony segment includes at least one guide tube and an extension extending distally from a distal end of the at least one guide tube. The extension is contactable with at least one of the plate and the bony segment with a passage of the guide tube aligned with a bone fastener hole through the plate and the distal end of the guide tube spaced from the plate.

    摘要: A measurement instrument is provided with indicia extending therealong. The measurement instrument indicia is correlated with an indicator of a reference instrument. The measurement instrument is positionable adjacent the entry location of a portal into a patient when the reference instrument is in the portal. The indicator of the reference instrument is correlated to a target location in the patient, and a location of the indicator along the indicia provides an indication of the optimal length for a retractor to be positioned in the portal.

    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.
