CD-cervical系统在枕颈区腹侧减压术中的应用

Application of CD-cervical system in anterior decompression of occipitocervical disorders

目的 探索和完善枕颈区腹侧损伤的手术治疗方法。 方法 经枕颈后外侧入路在进行枕颈前后方减压的同时 ,采用CD -cervical系统枕颈内固定 ,髂骨植骨融合 ,Ⅰ期重建枕颈部的稳定性。于 2 0 0 0年 1月～ 2 0 0 1年 1月共治疗 18例 ,其中枕寰区畸形伴寰枢脱位 13例 ,陈旧性齿状突骨折伴寰枢脱位 5例。 结果 全组病例无手术死亡及术后感染发生。 1例患者术后肢体运动障碍加重 ,术后 2周开始恢复。其余患者术后感觉运动功能均有不同程度改善。全组术后平均随访 6个月 ,内固定无松动 ,枕颈植骨融合。 结论 在完成枕颈部前后方减压的同时 ,应用CD-cervical系统做枕颈固定植骨融合 ,可在术后即刻恢复枕颈部稳定性 ,不仅有利于患者早期起床活动 。

Objective To explore operative treatment for occipitocervical ventrol disease. Methods CD cervical system was used for occipitocervical internal fixation, iliac bone graft fusion and primary reconstruction of stability of occipitocervical region during anterior decompression of occipitocervical region through transoccipitocervical posterolasteral approach in 18 patients who were admitted to our hospital from January 2000 to January 2001. Results There was no operation mortality or infection in all the cases. Neural function of one case was deteriorated postoperatively. Two weeks after operation the neural function began to recover. The follow up period ranged from 6 12 months. It revealed that sensory and muscular functions were improved. X ray films showed that CD cervical system was not loosened and occipitocervical bone graft was fused. Conclusions After anterior decompression of occipitocervical region CD cervical system can promote bone graft healing and stability of occipitocervical region.
