Surgical technique and the clinical outcomes of intersegmental fixation with an interspinous spacer (IFIS) for lumbar spinal instability are reported in this study. Four patients underwent surgery using this procedure. There were no surgical complications, and the clinical outcomes were satisfactory. Spinal alignment was maintained successfully as observed radiographically, and bone fusion was obtained in all cases. This technique may be an alternative for patients with degenerative lumbar disease such as spondylolisthesis and lumbar spinal stenosis (LSS) with mild spinal instability.
