    摘要： A surgical method for preparing a site for implantation of a spinal implant into a disc space in which the disc space is first distracted by a novel stepped distractor, followed by insertion of a novel guide sleeve including a proximal portion having an uninterrupted side wall and a distal portion having a side wall defining a longitudinal opening extending along its entire length. The guide sleeve is seated adjacent the disc space with the longitudinal opening positioned opposite the dural region of the spine to provide a working channel to the disc space. A cutting tool is then inserted through the guide sleeve to remove tissue and bone laterally extending into the interior of the guide sleeve through the longitudinal opening, but only as much as necessary for passage of the spinal implant. In a further embodiment, a protective barrier, including a pair of overlapping, flexible leaf members, is operably attached to the inside surface of the guide sleeve and positioned across the longitudinal opening to separate the inner region of the guide sleeve from the outer surgical environment.

    摘要： A spinal stabilization system, apparatus, and method are disclosed which include an interconnection mechanism for engaging stabilization members to one another. In one embodiment, the interconnection mechanism comprises a locking member having first and second threaded segments. An anchor member is provided having an upper segment and a lower segment, wherein the lower segment is structurally configured for engagement with a respective bone segment. A first stabilization member is connected to the upper segment of the anchor member. A locking member is engaged with the anchor member such that the first stabilization member is fixedly secured to the anchor member by a lower portion of the locking member having a first threaded segment. A second stabilization member is connected to an upper portion of the locking member by a cap that is threaded onto a second threaded segment of the locking member.
