Presented are the results after the surgical treatment (CDI) of 25 patients suffering from spondylolisthesis and of 25 patients with a lumbar or a sacral spondylodesis. The mean follow up reaches from 8.4 (spondylolisthesis) to 16.6 months (lumbar and sacral spondylodesis). 15 (60%) of the patients with spondylolisthesis showed an excellent or good result, in 3 (12%) the result was unsatisfactory. Only 7 of the patients of the second group were without further complaints, in 6 an amelioration of pain relief could be reached. The complications demonstrate the fault of the instrumentation in the beginning. After the development of a new screw the monosegmental fusion with CDI can be achieved in spondylolisthesis with a slipping to 70%, in more severe spondylolisthesis bisegmental fusion is necessary. The results in lumbar and sacral spondylodesis demonstrate that the operation should be only performed when all other methods have been unsuccessful.
本文呈现了25例腰椎滑脱患者和25例腰椎或骶椎融合患者接受手术治疗（CDI）后的结果。平均随访时间从8.4个月（腰椎滑脱）至16.6个月（腰椎和骶椎融合）。15例（60%）腰椎滑脱患者显示出优或良的结果，3例（12%）结果不满意。第二组中只有7例患者无进一步主诉，6例患者疼痛缓解有所改善。并发症显示出最初器械存在缺陷。在研发出新型螺钉后，对于滑脱至70%的腰椎滑脱患者可通过CDI实现单节段融合，对于更严重的腰椎滑脱则需要双节段融合。腰椎和骶椎融合的结果表明，只有在所有其他方法均未成功时才应进行该手术。
