Reduction and stabilization of grade IV spondylolisthesis.
Virtually any degree of spondylolisthesis can be reduced and held using variable screw placement (VSP) slotted plates and transpedicular screws. All of the soft tissue holding the displaced vertebrae must be stretched prior to pulling the vertebrae back into normal alignment. Complete control of the displaced vertebrae is gained through the transpedicular screws, and fixation is accomplished by bolting the screws to the spine plates that have been bent to achieve the proper lumbar lordosis. Ultimate stability is gained by both a bilateral lateral and interbody fusion.
