title: [Value of tomodensitometry in the diagnosis of lumbar disk hernias].
abstract: The authors relate their experiences concerning tomodensitometric examination to evaluate the herniation of a disk. 45 patients and 50 herniations of a disk have been studied. 39 herniations have sustained surgical procedures. The tomodensitometric examination and the radiculosaccography have been performed among these patients in order to compare the findings. The fact that there has only been 3 failures prove the reliability of tomodensitometric examination; among these failure there is 2 post-operative recurrences and one L4 L5 herniation. The radiculosaccography fails 5 times (1 L4 L5 herniation and 4 L5 S1 herniations). There is not any common negative in the two methods. Because of its total innocuity (no injection of any kind) the tomodensitometric examination seems to be the first exploration to prescribe when an herniation of a disk is resistant to clinical treatment and when a surgery is planned.
