目的：调查颈椎碳纤维椎间融合器下沉的次数，并确定其下沉的预测因素。方法：对2002年1月至2003年12月收治的所有颈椎突出症患者行颈椎碳纤维椎间融合术。复习了放射学检查，尤其注意到了下沉的存在。结果：在69例患者中，共置入96个融合器，其中29.2%的融合器下沉。在所有被调查的因素中，似乎只有吸烟可以预测下沉，而C6到C7插入显然有更高的下沉风险。下沉与结果或融合无关。结论：尽管以前从未描述过大量的椎间融合器下沉，但临床结果和融合率与文献报道相当。
OBJECTIVE: To investigate the number of subsidences of inserted cervical carbon fiber cages and to define predictive factors for subsidence.METHODS: All patients treated for a cervical herniated disc and fusion with a cervical carbon fiber cage between January 2002 and December 2003 were retrospectively identified. The radiological examinations were reviewed, and, especially, the presence of subsidence was noted. Possible predictive factors for subsidence were determined before the investigation.RESULTS: In 69 patients, there were 96 cages inserted, of which 29.2% subsided. Of all factors investigated, only smoking seemed to be predictive for subsidence, whereas insertion at C6 to C7 clearly had a higher risk at subsidence. Subsidence was not related to outcome or fusion.CONCLUSION: Although the high number of subsidence of cages has never been described before, clinical outcome and fusion rate is comparable with the literature.
