The normal lumbar central canal has a midsagittal diameter (front to back) greater than 13 mm, with an area of 1.45 cm 2. Relative stenosis is said to exist when the anterior-posterior canal diameter measures between 10 and 13 mm. Absolute stenosis of the lumbar canal exists anatomically when the anterior-posterior measurement is 10 mm or less.
