Comparing Cortical Bone Trajectory and Traditional Pedicle Screws in Transforaminal Lumbar Interbody Fusion: A Retrospective Cohort Study of One-Year Outcomes – Lumbar Fusion

Day Case Lumbar Fusion Surgery

This retrospective study compared the long-term outcomes of patients undergoing transforaminal lumbar interbody fusion (TLIF) using cortical bone trajectory (CBT) and traditional pedicle screw (TPS) techniques. The study included consecutive patients treated between 2010 and 2019. The results showed that there were no significant differences in perioperative and postoperative outcomes between the CBT TLIF group and the TPS TLIF group. Complications, length of stay, discharge destination, surgical revision rate, and fusion rates were all similar between the two groups. Therefore, the study concluded that CBT in TLIF procedures can provide equivalent outcomes to TPS in both the short- and long-term

ABSTRACT

INTRODUCTION: This is a retrospective study of consecutive patients undergoing transforaminal lumbar interbody fusion (TLIF) at a single institution. The objective of this study was to compare the long-term results associated with cortical bone trajectory (CBT) and traditional pedicle screw (TPS) via posterolateral approach in TLIF.

METHODS: Consecutive patients treated from November 2014 to March 2019 were included in the CBT TLIF group, while consecutive patients treated from October 2010 to August 2017 were included in the TPS TLIF group. Inclusion criteria comprised single-level or two-level TLIF for degenerative spondylolisthesis with stenosis and at least one year of clinical and radiographic follow-up. Variables of interest included pertinent preoperative, perioperative, and postoperative data. Non-parametric evaluation was performed using the Wilcoxon test. Fisher’s exact test was used to assess group differences for nominal data.

RESULTS: Overall, 140 patients met the inclusion criteria; 69 patients had CBT instrumentation (mean follow-up 526 days) and 71 patients underwent instrumentation placement via TPS (mean follow-up 825 days). Examination of perioperative and postoperative outcomes demonstrate comparable results between the groups with perioperative complications, length of stay, discharge destination, surgical revision rate, and fusion rates all being similar between groups (p = 0.1; p = 0.53; p = 0.091; p = 0.61; p = 0.665, respectively).

S: CBT in the setting of TLIF offer equivalent outcomes to TPS with TLIF at both short- and long-term intervals of care.
