Second illustrative case of VBDR subsidence through the inferior endplate after monosegmental ACR. Multiplanar CT reconstructions in the axial (a), median sagittal (b), paramedian sagittal (e) and coronal (c, f) plane showing a complete burst fracture of T12. The fracture may be misinterpreted as a burst-split fracture when analyzing the standard median sagittal and coronal reconstructions only. However, the axial CT reconstruction at the level of the inferior endplate (a) as well as the paramedian sagittal reconstruction (e) clearly depict multiple additional subtle fracture lines at the inferior endplate (indicated by white arrows). Intraoperative lateral radiograph (d) already showing minimal VBRD subsidence after positioning onto the “free floating” central inferior endplate fragment created by the presence of multiple fracture lines. Postoperative lateral radiographs and CT images at 1 week (gi) and 14 months (j) demonstrating VBDR subsidence through the inferior endplate and into the adjacent intervertebral disc. The central inferior endplate fragment below the VBDR is indicated by white arrows (h, i)
