Canal encroachment and the percentage of canal encroachment. Canal area measured by the PACS measurement software. A is the area of the injured vertebra, B and C are that of the two adjacent vertebrae, and the percentage of canal encroachment (%CE) was calculated as the area of the protrusion into the canal of the injured vertebra divided by the mean of the maxim canal area of the adjacent two vertebrae, that is %CE = 100-2A/(B + C) × 100.
