A predictive model of preoperative risk factors for venous thromboembolism after fusion for degenerative conditions of the thoracolumbar spine.

Background: The purpose of this study was to identify preoperative risk factors for VTE and develop a predictive model that can be integrated into electronic health records (EHRs).

Methods: Retrospective review of patients undergoing thoracolumbar fusion from 2016 to 2018 in the National Surgical Quality Improvement Program database was performed.

Results: Increasing age, BMI, and several other factors were significant predictors of increased risk for postoperative VTE.

Cortical bone trajectory instrumentation provides favorable perioperative outcomes compared to pedicle screws for single-level lumbar spinal stenosis and degenerative spondylolisthesis.

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.
