Abstract
To compare perioperative outcomes between cortical bone trajectory (CBT) instrumentation with pedicle screws (PS) in patients undergoing laminectomy and posterolateral fusion for single-level lumbar spinal stenosis, and degenerative grade I spondylolisthesis. A consecutive series of 91 patients from a single institution between January 2017 and July 2019 were retrospectively reviewed. Patients in CBT group had significantly shorter operative time, lower blood loss and shorter length of stay. CBT instrumentation demonstrated favorable perioperative outcomes that may enhance the overall value in patients undergoing laminectomy and posterolateral fusion for single-level lumbar spinal stenosis, and degenerative grade I spondylolisthesis.
