OBJECTIVE: 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. METHODS: A consecutive series of 91 patients from a single institution between January 2017 and July 2019 were retrospectively reviewed. RESULTS: Patients in CBT group had significantly shorter operative time, lower blood loss and shorter length of stay. CONCLUSION: 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.
