Risk Factors Analysis For Nerve Damage In Patients With Thoracolumbar And Lumbar Burst Fractures

Objective: To analyze the relationship between the posteriorligamentous complex (PLC) integrity, degrees of spinal stenosis and neuralfunction damage in cases with thoracolumbar and lumbar burst fractures.Methods: A total of156cases with thoracolumbar and lumbar burstfractures were included in this retrospective analysis, and data were analyzedin terms of value of sagittal diameter of spinal canal, the integrity of PLC andneural function damage.Results: Neural function damage was found in94patients. There was asignificant correlation between neural function damage and degrees of spinalstenosis. At the T12level, neural function damage showed the highestcorrelation with degrees of spinal stenosis（Rs=0.87、P＜0.001）. At the T11level, neural function damage showed the lowest correlation with degrees ofspinal stenosis（Rs=0.59、P＜0.001）. The PLC integrity was significantlycorrelated with neural function damage（OR=3.82，P＜0.001）.Conclusion: The PLC integrity and degrees of spinal stenosis aresignificantly correlated with neural function damage in patients withthoracolumbar fracture.
