A simple aid for reposition of spondylolisthesis with the Fixateur interne is presented. The modification consists of a metric thread, which is cut in the end of the SCHANZ screw, a fitting butterfly nut and a distance tube. This instrument allows a well-dosed and controlled extension and reposition of the dislocated vertebra in all planes. No other instruments or implants, which may hinder the operation, are necessary. After the reposition the bone graft may be inserted from ventral or from dorsal. The dorsal intercorporal spondylodesis saves time, means a lower trauma for the patient and has the possibility for interfragmental compression.
介绍了一种使用内部固定器复位腰椎滑脱的简易辅助工具。该改良工具包括一个在斯氏针末端切割的公制螺纹、一个配套的蝶形螺母和一个定距管。该器械能在所有平面上对脱位椎体进行精确且可控的牵张和复位。无需其他可能妨碍手术的器械或植入物。复位后，可从前方或后方插入骨移植材料。后路椎间融合术节省时间，对患者创伤较小，且有可能进行椎间加压。
