In 220 patients in whom ventral fusion according to Cloward was performed because of traumatic or degenerative discopathy, the pre-surgery finding of discography was compared with the finding established during the operation. It was found that pre-operative discography enables to diagnose damage of the nucleus pulposus and anulus fibrosus, as well as tearing of the posterior and anterior longitudinal ligament. It is emphasized that in degenerative damage, escape of the contrast medium in ventral direction merely represents backflow of the contrast medium along the puncture channel and rarely represents rupture of the anterior longitudinal ligament. Side localisation is possible by means of the semioblique x-ray. In case of a traumatic damage, at least two disc spaces should be diagnosed.
对220例因创伤性或退变性椎间盘病而根据克洛德法进行前路融合术的患者，将术前椎间盘造影的结果与手术中确定的结果进行了比较。发现术前椎间盘造影能够诊断髓核和纤维环的损伤，以及后纵韧带和前纵韧带的撕裂。需要强调的是，在退变性损伤中，造影剂向腹侧溢出仅代表造影剂沿穿刺通道的回流，很少代表前纵韧带的破裂。通过半斜位X线片可以进行侧方定位。对于创伤性损伤，至少应诊断两个椎间盘间隙。
