Categorization of intervertebral discs (IVDs). IVDs were categorized according to the locations of adjacent vertebral fractures (VFs). The VF-negative (VF-) group was defined as those IVDs having no fracture in an adjacent vertebral body. The VF-positive (VF+) group was defined as those IVDs having a fracture in an adjacent vertebral body. The VF-positive group was further classified into three subgroups: those IVDs superior to the VF (superior), those IVDs inferior to the VF (inferior), and those IVDs located between VFs (bilateral)
