Figure 7: Schematic representation of (a) Denis classification: fractures involving the alar region (zone 1), sacral neural foramina (zone 2), and the sacral spinal canal (zone 3). (b) Subclassification of Denis zone 3 fractures by Roy-Camille modified by Strange-Vognsen into types 1, 2, 3, and 4 (c) High TSFs are usually associated with unilateral or bilateral vertical fracture through the neuroforamina, resulting in U, H, λ, or T pattern fractures. (d) Low TSF
