The influence of titanium-coated poryetheretherketone cages in fusion status after posterior lumbar interbody fusion with cortical bone trajectory screw fixation – Lumbar Fusion

Day Case Lumbar Fusion Surgery

The article evaluates the use of titanium-coated polyetheretherketone (TP) cages in posterior lumbar interbody fusion (PLIF) with cortical bone trajectory (CBT) screw fixation. The study compares the fusion outcomes of 68 patients who underwent CBT-PLIF with TP cages and 89 patients who underwent CBT-PLIF with carbon fiber-reinforced polyetheretherketone (CP) cages. The results show no significant difference in fusion rates between the two groups at 1 and 2 years postoperatively. However, the CP group exhibited a significant improvement in fusion rate from 1 to 2 years, while no significant improvement was observed in the TP group. The study suggests that TP cages may enhance the fusion process, but their definitive efficacy in CBT-PLIF remains uncertain

S: Examination of temporal changes in fusion rates reveals that only the TP group achieved a peak fusion rate 1 year postoperatively. This implies that TP cages may enhance the fusion process even after CBT-PLIF. Nevertheless, the definitive efficacy of TP cages for CBT-PLIF remains uncertain in the context of overall fusion rates.

ABSTRACT

OBJECTIVE: Posterior lumbar interbody fusion (PLIF) with cortical bone trajectory (CBT) screw fixation (CBT-PLIF) shows potential for reducing adjacent segmental disease. Previously, our investigations revealed a relatively lower fusion rate with the use of carbon fiber-reinforced polyetheretherketone (CP) cages in CBT-PLIF compared to traditional pedicle screw fixation (PS-PLIF) employing CP cages. This study aims to evaluate whether the implementation of titanium-coated polyetheretherketone (TP) cages can enhance fusion outcomes in CBT-PLIF.

METHODS: A retrospective analysis was conducted on 68 consecutive patients who underwent CBT-PLIF with TP cages (TP group) and 89 patients who underwent CBT-PLIF with CP cages (CP group). Fusion status was assessed using computed tomography at 1 year postoperatively and dynamic plain radiographs at 2 years postoperatively.

RESULTS: No statistically significant differences in fusion rates were observed at 1 and 2 years postoperatively between the TP group (86.8% and 89.7%, respectively) and the CP group (77.5% and 88.8%, respectively). Notably, the CP group exhibited a significant improvement in fusion rate from 1 to 2 years postoperatively (p = 0.002), while no significant improvement was observed in the TP group.

S: Examination of temporal changes in fusion rates reveals that only the TP group achieved a peak fusion rate 1 year postoperatively. This implies that TP cages may enhance the fusion process even after CBT-PLIF. Nevertheless, the definitive efficacy of TP cages for CBT-PLIF remains uncertain in the context of overall fusion rates.
