Zero－P椎间融合术治疗脊髓型颈椎病的临床疗效

Zero-P interbody fusion clinical efficacy in treatment of cervical myelopathy

目的：探讨颈椎前路椎间融合固定系统（Zero －P）治疗脊髓型颈椎病的临床疗效。方法：回顾性分析2010年6月～2013年6月在我院手术治疗的脊髓型颈椎病患者88例，根据手术方法不同分为Zero－P组行前路椎间盘切除Zero－P内固定、cage组行前路椎间盘切除椎间融合与钢板内固定，每组各44例。比较2组手术情况及临床疗效。结果：Zero－P组手术时间、术中出血量及住院时间显著优于cage组，2组比较具有统计学意义（P＜0．01）；2组术前、术后3个月及终访JOA评分、融合率比较差异均无统计学意义；术后Zero－P组出现1例髂骨供区轻度酸痛；cage组出现2例钛板松动未融合，1例明显吞咽异物感。结论：Zero－P椎间融合术手术时间短、术中出血少、融合率高，且术后并发症少，值得临床推广。

Objective：To investigate the road before cervical interbody fusion fixation system （ Zero-P） treatment of cervical myelop-athy clinical efficacy.Methods：A retrospective analysis of June 2010 June 2013 in our hospital surgical treatment of patients with cervical myelopathy 88 cases, according to the surgical methods were divided into groups of rows before the Zero-P discectomy Zero-P fixation, cage group anterior discectomy and interbody fusion with plate fixation, 44 cases in each group.Were compared surgical and clinical effi-cacy.Results：Zero-P operative time, blood loss and length of hospital stay was significantly better than the cage group between the two groups was statistically significant （ P 〈0.01）;the two groups before surgery, three months and a final visit JOA score, integration There was no significant difference in the rate;after Zero-P group had one case of mild iliac crest donor site pain;cage group had two cases ti-tanium loose unfused, one case of obvious foreign body sensation swallowing.Conclusion：Zero-P interbody fusion could shorten opera-tive time, less blood loss, fusion rate, and fewer complications, worthy of promotion.
