Abstract:
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.
