新型低切迹接骨板系统与Zero⁃P治疗单节段神经根型颈椎病的疗效分析

Clinical efficacy of a new low notch plate system and Zero⁃P in the treatment of single segment cervical spondylotic radiculopathy

目的对比新型低切迹接骨板系统(卡门同步适稳颈椎融合系统)与Zero⁃p治疗单节段神经根型颈椎病的临床疗效。方法2015年1月~2020年1月收治的单节段神经根型颈椎病病人48例,根据手术方法分为两组,其中观察组26例,采用新型低切迹钢板系统治疗,对照组22例,采用Zero⁃P治疗,比较两组病人手术时间、术中出血量、术后吞咽困难发生率,以及术前、术后的日本骨科协会评分(JOA)、颈椎功能障碍指数(NDI)、疼痛视觉模拟评分(VAS)以及术后差异Cobb角和椎间隙高度。结果两组病人的手术时间、术中出血量、术后吞咽困难发生率比较均无统计学意义(P均>0.05)。所有病人均获得随访,随访12~15个月,平均随访(12.6±0.7)个月。且术前、术后3、12个月两组病人JOA评分、NDI指数以及疼痛VAS评分比较,差异无统计学意义(P>0.05)。结论新型低切迹接骨板系统治疗单节段神经根型颈椎病的临床疗效与Zero⁃P相当,是一种可靠的新型颈椎前路内固定系统。

Objective To compare the clinical efficacy of a new low notch plate system(Carmen synchronous adaptive cervical fusion system)and Zero⁃p in the treatment of single level cervical spondylotic radiculopathy(CSR).Methods Retrospective analysis was made on 48 patients with single level cervical spondylosis of nerve root type admitted from January 2015 to January 2020,including 26 patients with new low notch steel plate system(observation group)and 22 patients with Zero⁃P(control group).The operation duration,intraoperative blood loss,incidence of postoperative dysphagia,preoperative and postoperative JOA scores,cervical dysfunction index(NDI)Visual analog score of pain(VAS)and Cobb angle and intervertebral space height of postoperative imaging.Results There was no significant difference between the two groups in terms of operation time,intraoperative blood loss and the incidence of postoperative dysphagia(P>0.05).All patients were followed up for 12⁃15 months,with an average of(12.6±0.7)months.There was no significant difference in JOA score,NDI index and VAS score of pain between the two groups before and 3 and 12 months after operation(P>0.05).Conclusion The clinical efficacy of the new low notch plate system in the treatment of single segment cervical spondylotic radiculopathy is equivalent to Zero⁃P,and it is a reliable new type of anterior cervical internal fixation system.
