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.
Keywords: Length of stay; Operative time; Spinal stenosis; Spondylolisthesis; Surgical blood loss.
