Abstract
An implantable spine fixation apparatus and method, the apparatus including a pair of longitudinal rods placed on each side of the spinous process. Several side arm clamps are attached to the longitudinal rods with their lateral arms extending outwardly from the longitudinal rods. Clamps are mounted to the lateral arms and both affixed to the bone of the spine and clamped to the lateral arms by bone screws inserted into the bone of the spine. Cross link plates are mounted to paired side arm clamps to secure the relative positions of the longitudinal rods. The method includes providing the bone screw with the optimal angular orientation for fixation of the bone screw to the bone. The method also includes adjustably affixing the implantable fixation apparatus relative to the spine for improving bone grafting.
