Abstract

A dorsally placed transacrally fixed surgical implant is described for correcting and supporting the spinal column with the implant being particularly useful for aligning and stabilizing the lumbosacral junction. Direct sacral fixation is achieved utilizing a contoured metallic base plate that is firmly fixed to the sacrum by means of a plurality of screws, which screws are angularly disposed with respect to one another to maximize retention of the base plate on the sacrum. A pair of spine engagable rods, contoured to the desired spinal column configuration, have one end inserted into sockets on the base plate with the rods being locked against rotation or other movement relative to the base plate. A total fixation system is provided that has flexibility with respect to rod utilizable components, with the rods having bridges, hooks and/or wires spaced along the rods for engagement with vertebrae of the spinal column to hold the spinal column in the desired position, once achieved, as determined by the contour of the rods.
