An apparatus and a method for performing spondylolisthesis reduction utilizing spinal link implants, the apparatus comprising a jack which is temporarily affixed to the spinal links, where the jack is constructed to provide leverage or fulcrum points such that the vertebrae or sacrum can be moved as required for, proper realignment and to position adjacent link members for connection. The jack comprises a pair of outrigger members connected to a levering member such that each is free to pivot, whereby the relative angle between the members may be altered by movement of the levering member, which is provided with at least one handle to be gripped by the surgeon. Optionally, an outrigger stabilizer member is also provided. The ends of the outrigger members are provided with connector means for temporarily securing the outriggers to the linking members in a secure manner such that any manipulation of the outrigger members is transferred to the spinal link members and thus to the vertebra or sacrum to which they are affixed. With the sacrum and vertebrae properly aligned and positioned, the spinal links are joined to form a rigid structure and the jack is removed.

An apparatus, method and system for treating spinal conditions by moving or spatially fixing at least one vertebra relative to another vertebra. The invention includes a link member the ends of which are configured to be secured to adjacent vertebrae and which are offset from a central portion of the link member. The link members can be in the form of a C-shaped or V-shaped rod or plate to form the offset. The offset provides increased bone volume that can be used for grafts or fusion. Attachment structure in the form of bone screws, bolts, or hook members are provided to secure the link members to respective vertebrae or other bones. A plurality of link members can be connected in chain-like fashion to connect multiple points on a plurality of vertebrae or other bones even though those points are nonlinear. In another aspect of the invention, a multi-directional attachment member is provided and may be used with the link members to form a spinal implant or external bone fixation system.

A cervical plate for use alone or in combination with a cervical link system is described. The cervical plate may be generally quadrangular with a bone screw aperture at each corner area. An oval or elongated bone screw aperture is positioned in the central area of the cervical plate to accommodate intercalation of a bone screw and consequent vertical positioning of the plate. The plate may be secured to at least one link of a cervical link system or used to facilitate revision surgery.

A knot formed by providing a bight in a strand, then forming a lark's head in the bight so as to produce a pair of adjacent loops and a pair of free ends extending from the loops, then passing the free ends around the object and passing them through both said loops in series, and then tying at least one overhand hitch in the free ends to resist any forces tending to pull the free ends back through the loops. The knot is useful in orthopedic surgical procedures.
