A laparoscopic surgical technique is provided for preparing a site for
implantation of a novel fusion device or implant. In accordance with one
embodiment of the technique, a laparoscope is provided having an outer
sleeve with distraction fingers at one end to distract the disc space.
The laparoscope provides a sealed working channel to the disc space,
through which the disc space is distracted, the vertebral endplates and
surrounding disc is reamed, and the fusion device inserted. A distraction
plug is provided for centering the outer sleeve and for providing midline
distraction of the disc space. In one embodiment, a fusion device
includes diverging bone screws passing through an end wall and upper and
lower walls of the device to engage the adjacent vertebrae. In another
embodiment, a connector plate is engaged to bilaterally position fusion
devices to prevent rotation and resist expulsion of the devices from the
disc space.
