Cervical anterior fusion with iliac bone crest has become a popular surgical technique for cervical spondylotic disease. Since about 10 years ago, we have substituted hydroxyapatite ceramic spacer for autologous graft because of postoperative painful hip syndrome. Fourteen patients who underwent cervical anterior fusion with ceramic spacer were evaluated by plain radiographs for over eight years postoperatively. In six among the fourteen patients plain films demonstrated minimal stenosis of intervertebral disc height, of which the ratio ranged from 15% to 28% (mean 22%). The increase in mobility of the adjacent segment after fusion was noted in ten of the fourteen patients, although the ratio ranged only between 12% and 24% (mean 18%). In none of all the patients did dynamic plain films show cervical instability such as slippage and swan neck deformity. It seems that anterior fusion with ceramic spacer is a useful and safe method for a cervical spondylotic disease.
颈椎前路髂骨嵴融合术已成为治疗颈椎病的一种常用手术技术。大约10年前，由于术后出现髋关节疼痛综合征，我们开始用羟基磷灰石陶瓷椎间融合器替代自体骨移植。对14例行颈椎前路陶瓷椎间融合器融合术的患者进行了术后8年以上的X线平片评估。14例患者中有6例平片显示椎间盘高度轻度狭窄，狭窄率在15%至28%之间（平均22%）。14例患者中有10例注意到融合后相邻节段活动度增加，尽管增加率仅在12%至24%之间（平均18%）。所有患者的动态平片均未显示颈椎不稳，如滑脱和天鹅颈畸形。看来，陶瓷椎间融合器前路融合术是治疗颈椎病的一种有用且安全的方法。
