The system further includes a plate having a retaining element for preventing backout of screws inserted through the plate. Instruments and methods for attaching the plate to the spinal column are also provided.

Abstract: This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. A cannula is inserted to create a working channel through the skin and tissue of a patient using a transforaminal approach to the disc space. A viewing element is used to visualize working end of the cannula and the disc space. A facetectomy is performed through the working channel to access the disc space. The disc space is prepared with various instruments, such as distractors, shims, chisels and distractor-cutters that extend through the working channel. At least implant is inserted into the disc space. The procedure allows bi-lateral support of the adjacent vertebrae with the at least one implant inserted via a unitary, minimally invasive approach to disc space.

Abstract: An instrument and method for reducing a vertebral rod into an anchor attached to a vertebral member. The instrument may include a gripper configured to attach to an anchor, an elongated shaft extending along a longitudinal axis between opposing jaws of the gripper, and a reducing element disposed at least partially outside the first and second jaws of the gripper and configured to engage with the vertebral rod. A release device may also be disposed about the elongated shaft and may be movable relative thereto such that the release device may be selectively engaged with a threaded outer surface of the elongated shaft. The reducing element may therefore be alternatively slidable relative to the gripper or threadably movable relative to the gripper by interaction with the elongated shaft, depending on a position of the release device.

Abstract: 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.

Abstract: A plating system for stabilization of a bony segment includes a plate engageable to at least first and second bony elements. For spinal stabilization, the plate is attached at least to first and second vertebrae with at least one bone fastener in each vertebra. Retaining members are attachable to the plate to prevent the bone fasteners from backing out of the plate. One retaining member is a variable retaining member that allows the bone fasteners to toggle in the plate without interference. A second retaining member is a fixed retaining member that fixes the bone fasteners relative to the plate.

Abstract: An intersomatic implant (1a, 1b) maintains bone graft material in a receiving cavity formed in a disc in order to obtain intervertebral fusion. The implant (1a, 1b) includes of a plurality of parts provided with means for in situ connection of two consecutive parts. Instruments (33) are used to connect these implants (1a, 1b) and a tool assists in introducing these implants (1a, 1b) into the cavity formed in the disc.

Abstract: A disc preparation system includes an oscillating rasp for preparation of vertebral endplates and a central reamer for reaming a pair of kidney-shaped grooves into the vertebral endplate. The oscillating rasp is powered by a rotary power source. A linkage assembly is coupled to the rotary power source to convert the rotary motion into a reciprocating motion. A pair of rasps plates, which are linked to the linkage assembly, linearly reciprocate in opposite directions in response to the reciprocating motion of the linkage assembly. In one form, the central reamer includes a pair of cutting elements that are coupled to the rotary power source in order to rotate in response to rotational movement from the rotary power source. In another form, the central reamer includes a single cutting element coupled to an angled reamer handle and a reamer guide.

Abstract: This invention relates to implants formed from donor bone for use in lumbar interbody fusion procedures and instruments for performing such procedures.
