Abstract Objective The aim of this study was to evaluate the outcomes of cortical bone trajectory (CBT) screws in the posterior lumbar fusion surgery of lumbar disease with osteoporosis by a retrospective study, a relatively new technique. Methods This is a retrospective cohort study. All patients that underwent circumferential lumbar interbody fusion with CBT screws in our hospital from 2015 to 2018 were reviewed. Patient age, clinical outcome with visual analogue scale (VAS) and Oswestry Disability Index (ODI), operative blood loss, hospital stay and the fusion rate were evaluated. Results All patients obtained follow-up 16 to 24 months postoperative, with an average of 19.2 months. Oswestry Disability Indexes and Visual Analogue Scores improved significantly at 3 months postoperative. Mean procedural time was 183.2 min. The mean operative blood loss was 375.7 mL. The mean hospital stay was 4.56 days. The fusion was obtained in 100% of cases. Mean ODI and VAS index postoperative improved with statistical significance. Conclusion The use of cortical bone trajectory (CBT) screws for interbody fusion is safe and effective to patients with osteoporosis. While the technique has less trauma, shorter operative time, hospital stays and good fusion rate.
