Computed tomographic (CT) demonstration of calcification of the ligamenta flava of the lumbosacral spine associated with protrusion of the intervertebral disc.
Axial computed tomographic (CT) scan of the lumbosacral region was performed in 220 patients. The patient population was divided into three groups. The control group included 40 elderly patients without calcification of the ligamenta flava. The second group included 150 patients with posterior protrusion of the intervertebral discs. The third group included 30 patients with spinal stenosis. More than 80% of the patients of the second and the third group had calcification of the ligamenta flava. The diagnostic and practical importance of these findings is discussed.
