Abstract
In accordance with one exemplary embodiment of the invention, an anterolateral rod fixation device includes a pair of rods which can be fixed in substantially parallel relationship to the anterolateral vertebral body by cannulated fixation screws and associated locking screws. Upper or lower ends of the rods are provided with vertical slots to facilitate independent screw placement, and to permit relative movement between the rods and fixation screws upon removal of the locking screws. A pair of cross links are provided for rigid interconnection between the rods. Thus, in accordance with one aspect of the invention, there is provided an anterolateral spinal fixation system comprising a pair of substantially parallel fixation members, each provided with means for enabling varied fixation screw placement; a pair of cross links extending between the parallel fixation members; the cross links extending through slots provided in the parallel fixation members and rigidly secured therein.
