[Significance of discography and ossovenography in patients with cervical ventral fusion]

The value of ossovenography and discography is analysed. These examinations are indicated in operativ assessment of patients submitted to cervical ventral fusion. Discography revealed more advantages than ossovenography. The importance of oblique views in discography for evaluation of the site of disc damage is stressed. Ossovenography is superior to discography in severe degenerative lesions and patients with short neck.
