摘要: 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.
