A Network Meta-Analysis on the Surgical Management of Thoracolumbar Burst Fractures: Anterior, Posterior, and Combined

Abstract

Background Thoracolumbar burst fractures (BFs) are traumatic lesions instigated by compression forces. Canal compression and compromise may lead to neurological deficits. Optimal surgical management is yet to be fully defined since various approaches such as anterior, posterior, or combined exist. This study aims to determine the operative performance of these three treatment modalities. Methods In accordance with the PRISMA guidelines, a systematic review was performed, identifying studies comparing anterior, posterior, and/or combined surgical approaches in patients with thoracolumbar BFs. To analyze available evidence, a Bayesian network meta-analysis framework was utilized. Results In this study, 16 studies were included. The shortest operative times and lowest operative blood losses were found for a posterior approach. The length of stay (LoS) was shorter with the posterior approach compared with the other two modalities. Return to work, postoperative kyphotic angle (PKA), and complications all favored the posterior approach. The visual analog scale score was similar between groups. Conclusions This study suggests that the posterior approach has significant advantages in terms of operative time, blood loss, LoS, PKA, return to work, and complication rates when compared to the other approaches. Treatment should remain an individualized process, and before choosing an approach, factors such as patient characteristics, surgeon experience, and hospital settings should be considered.
