Based on 262 radiographic examinations done during two years the authors have analyzed the compatibility of the radiographic image with the clinical examinations and with the operation results. In the analysis the most frequently occurring lesion level having the character of hernia of the nucleus pulposus, age, sex, and the duration of the disease symptoms were taken into account. The effectiveness of the method, which was verified by surgery was 86.3%. The result is in good agreement with literature data. Therefore, the method can be still recommended, particularly for the x-ray laboratories, which have no possibility to apply non-invasive techniques.
