ObjectiveThe ideal management of thoracolumbar burst fracture (TLBF) remains controversial. We conducted this study to compare the effectiveness and safety of trans-Kambin triangle versus transpedicular bone grafting combined with posterior internal fixation (PIF) for TLBF.MethodsFifty-four patients were retrospectively analyzed and divided into 2 groups: the observation group (PIF combined with bone grafting via the Kambin triangle, n = 28) and the control group (PIF combined with bone grafting via transpedicular, n = 26). The anterior vertebral height ratio, sagittal Cobb angle, visual analog scale score, Oswestry Disability Index, bone healing rate, and neurologic complications were measured.ResultsAll patients were followed up regularly for a mean period of 17.94 months (12 - 24 months). The anterior vertebral height ratio in the observation group was higher than that in the control group (93.93 ± 2.92 vs. 89.90 ± 5.54%, P = 0.006), and the loss of correction was lower (1.59 ± 1.20 vs. 3.00 ± 1.98%, P = 0.008). The observation group had lower sagittal Cobb angle at final follow-up (8.68 ± 3.75 vs. 11.33 ± 4.77 degrees, P = 0.046) and less correction loss (1.96 ± 1.32 ± 1.15 vs. 3.90 ± 2.39 degrees, P = 0.002). The visual analog scale score and Oswestry Disability Index in the observation group were lower (0.61 ± 0.43 vs. 0.92 ± 0.38, P = 0.016; 15.86 ± 4.11 vs. 19.18 ± 4.04, P = 0.010), while the fracture healing rate showed no significant difference (P > 0.05). No internal fixation failure or neurologic complications occurred in both groups during the follow-up.ConclusionsBone grafting via the Kambin triangle combined with PIF is a safe and effective technology for thoracolumbar burst fracture.Copyright © 2021 Elsevier Inc.
