Perioperative outcomes. Patient data is provided for laminectomy and posterolateral fusion for single level lumbar stenosis and degenerative spondylolisthesis. PS – Pedicle screw; CBT – Cortical bone trajectory; SD – Standard deviation; EBL – Estimated blood loss; LOS – Length of stay; OR – Operating room. † denotes statistical significance with p < 0.05.
