OBJECTIVE: To review the historical thoracolumbar burst fractures (TLBFs) classifications and discuss the probable gaps for their clinical validation. SUMMARY OF BACKGROUND DATA: Despite multiple classification schemes, the treatment decisions for TLBFs in neurologically intact patients remain controversial. There are gaps between the current classifications and their predictive validation. METHODS: A narrative literature review. RESULTS: The potential barriers to establishing the predictive value of the current classifications of TLBFs could be connected to validation studies' flaws such as nonvalidated outcome measures and challenges of randomization. It could also be related to limited interobserver reliability in diagnosing A3/A4 fractures. Finally, it might be attributed to the inability to incorporate all prognostic variables, such as computed tomography (CT) parameters, patient-related factors, and traumatic disc injury, may result in failed validation. CONCLUSION: AOSpine Patient and Clinical Reported Outcome Spine Trauma (PROST) and a recently proposed natural experiment observational study hold promise for mitigating methodological challenges. A structured approach for distinguishing A3/A4 fractures and standardized CT criteria for PLC injury is critical to improving reliability. Finally, a treatment algorithm incorporating all potential prognostic variables, independent of the morphologic classification, may improve the predictive value of the classification. M...
