Note:—sag indicates sagittal reformations; ax, axial reformations.
↵a Cortex, trabeculae, and integrity were assessed on each cervical vertebral segment (eg, C3); alignment was assessed on each cervical level (eg, C3–4). The least visible cortices of each vertebral body and facet joint were used for this analysis.
