Effects of Spinal Instrumentation on Fusion of the Lumbosacral Spine

Abstract

Use of pedicle screw and rod fixation with the Edwards system led to significantly improved results in lumbosacral fusions over autogenous bone graft alone, with a lower complication rate. The use of spinal is a valuable adjunct to achieve lumbosacral fusion in patients who have undergone decompressive surgery for the spine.
