后路单开门减压经硬膜突出髓核摘除治疗颈椎管狭窄合并颈椎间盘突出症

Posterior single-door decompression and transdural nucleus extraction to treat cervical spinal stenosis and cervical disc herniation

目的探讨后路单开门减压经硬膜摘除突出髓核治疗颈椎管狭窄合并颈椎间盘突出症的临床疗效。方法回顾性分析2009年6月至2018年8月,我院采用颈椎后路经硬膜切除突出髓核33例的临床资料。评估该术式手术前后日本骨科协会(Japanese orthopaedic association,JOA)评分、颈椎管矢状径、颈椎弯曲类型等变化情况。结果本组JOA评分从术前(7.75±1.52)分升至术后(14.75±0.91)分,差异有统计学意义(P<0.05),椎管矢状径从术前(6.37±1.62)mm增至术后(10.4±1.77)mm,差异有统计学意义(P<0.05),颈椎弯曲类型术前、术后相比差异无统计学意义(P>0.05)。结论后路单开门减压经硬膜突出髓核摘除术是一种治疗多节段颈椎管狭窄合并颈椎间盘突出的有效术式。

Objective To explore the clinical effect of posterior single-door decompression and dural excision of the nucleus pulposus to treat cervical spinal stenosis and cervical disc herniation.Methods Retrospectively analyzed the clinical data of 33 patients with jugular nucleus pulposus protruding from the posterior cervical spine through dural resection from June 2009 to August 2018,and evaluated the Japanese orthopaedic association (JOA) score before and after the operation,Sagittal diameter of cervical spinal canal before and after the operation,type of cervical spine curvature before and after the operation and other changes.Results The JOA score increased from preoperative(7.75±1.52) points to postoperative (14.75±0.91) points,the difference was statistically significant (P < 0.05),and the sagittal diameter of the spinal canal increased from preoperative (6.37±1.62) mm to preoperative After (10.4±1.77) mm,the difference was statistically significant (P < 0.05),and there was no statistically significant difference between the types of cervical curvature before and after surgery (P > 0.05).Conclusions Posterior single-door decompression and transdural nucleus pulposectomy is an effective method for the treatment of multi-segment cervical spinal stenosis and cervical disc herniation.
