Soft cervical disc herniations.

The authors report their findings in a series of 51 patients suffering from typical cervical radiculopathy. With the aid of the CT scanner and intravenous injection of a contrast medium, the quality and resolution of the resulting images allowed neurosurgical intervention in 42 patients in whom the symptomatology alone was not sufficiently informative to allow successful treatment. In most cases the CT images allowed an accurate diagnosis and revealed a free fragment that had torn the common posterior vertebra ligament.
