目的探讨前路与后路减压手术治疗颈椎后纵韧带骨化(ossification of posterior longitudinal ligament,OPLL)的效果及对术后C5神经根麻痹的影响。方法回顾性分析2012年1月至2015年12月本文作者收治的颈椎后纵韧带骨化(OPLL)病例,依手术方法分为前路减压融合术组(简称"前路组")与后路单开门椎管扩大成形术组(简称"后路组")。对比分析2组的术后JOA评分改善率、C5神经根麻痹发生率和颈椎Cobb角。采用SPSS 13.0软件对数据进行处理。结果纳入27例,全部患者原有症状术后获不同程度改善,JOA评分改善率为(59.8±19.6)%,未发生脑脊液漏和感染等并发症。5例发生术后C5神经根麻痹,发生率为18.5%;前路组与后路组患者在年龄、术前JOA评分、Cobb角及随访时间等方面差异无统计学意义(P〉0.05)。2组术后JOA评分、末次随访JOA评分及改善率无显著差异(P〉0.05)。前路组2例发生术后C5神经根麻痹,发生率为16.7%。后路组3例发生术后C5神经根麻痹,发生率为20.0%;2组C5神经根麻痹发生率差异无统计学意义(P〉0.05)。结论前路和后路减压手术治疗颈椎OPLL均安全有效,对术后C5神经根麻痹的影响无显著差异。
Objective To study the efficacy of surgical treatment for cervical myelopathy caused by ossification of posterior longitudinal ligament( OPLL) and the incidences of postoperative C5 palsy. Methods Twenty-seven cases with surgical treatment of OPLL from Jan 2012 to Dec 2015 were included in this retrospective analysis. The JOA score,incidence of C5 palsy and cervical Cobb angle were recorded as efficacy assessment. Results Alleviation in JOA score was revealed in all 27 patients after surgical treatment( 59. 8% ±19. 6%),without record of CSF leakage and infection or other complications. There were 5 cases( 18. 5%)with C5 palsy. There was no significant difference in age,JOA score before treatment,JOA score after treatment,JOA score at last follow-up or JOA improvement rate between patients received anterior decompression and posterior laminoplasty,nor the incidence of C5 palsy. Conclusion Surgical treatment including anterior or posterior approach is effective and safe for myelopathy caused by OPLL.
