摘要/Abstract

摘要： 目的观察颈后路有限椎板切除联合神经根管减压术在降低C₅神经根麻痹及其促进神经功能改善的作用。方法回顾性分析2014年3月至2016年5月69例在本院接受手术治疗的多节段脊髓型颈椎病患者,其中,38例采用有限椎板切除、神经根管减压内固定术治疗(A组),31例采用常规椎板切除内固定术治疗(B组)。术后观察患者神经功能恢复、颈椎曲度指数变化及C₅神经根麻痹发生情况。结果所有手术均顺利完成。A组患者椎板切除宽度(16.8±2.1) mm,显著小于B组(21.7±2.5) mm (t=8.849, P<0.001)。两组在手术时间、术中出血量上比较无显著性差异(t<0.439, P>0.05)。术后两组日本骨科协会(JOA)评分持续性升高(F>42.996, P<0.05),不同时间点组间比较无显著性差异(t<1.021, P>0.05);颈椎曲度指数较术前有改善,且维持至末次随访(F>86.379, P<0.05),不同时间点组间比较无显著性差异(t<0.943, P>0.05)。A组术后C₅水平脊髓漂移距离(2.5±0.5) mm,显著小于B组(3.6±0.7) mm (t=7.602, P<0.001)。两组神经功能改善率无显著性差异(t=0.724, P=0.471)。A组C₅神经根麻痹发生率5.2%(2/38),低于B组22.5%(7/31) (χ²=4.514, P=0.034)。结论颈椎有限椎板切除联合神经根管减压术可解除脊髓压迫并限制脊髓过度向后漂移,促进神经功能恢复的同时降低C₅神经根麻痹的发生。

Abstract: Objective To observe the effect of limited laminectomy combined with foraminal stenosis decompression on preventing C₅ nerve root palsy and improving neurological function. Methods From March, 2014 to May, 2016, 69 patients with multi-segment cervical spondylotic myelopathy underwent surgical treatment in our hospital were included. Thirty-eight patients (group A) were treated with limited laminectomy combined with foraminal stenosis decompression and internal fixation, and 31 patients (group B) underwent routine laminectomy and internal fixation. The postoperative neurological recovery rate, cervical curvature index (CCI) and C₅ palsy rate were recorded and analyzed. Results No spinal cord and nerve injury occurred during the operation. The width of laminectomy was (16.8±2.1) mm in group A, and was significantly less than (21.7±2.5) mm in group B (t=8.849, P<0.001). There was no significant difference in operation time and intraoperative blood loss between two groups (t<0.439, P>0.05). The Japanese Orthopaedic Association (JOA) score increased continuously after surgery in both groups (F>42.996, P<0.05), and no significant difference was found between them at each time point (t<1.021, P>0.05). The cervical curvature index improved after surgery (F>86.379, P<0.05), and no significant difference was found between them at each time point (t<0.943, P>0.05). The spinal cord drift distance was (3.6±0.7) mm in group A, and ws significantly shorter than (2.5±0.5) mm in group B (t=7.602, P<0.001). There was no significantly difference in the neurological recovery rate between two groups (t=0.724, P=0.471). The C₅ palsy rate was lower in group A (5.2%, 2/38) than in group B (22.5%, 7/31) (χ²=4.514, P=0.034). Conclusion Limited laminectomy combined with foraminal stenosis decompression could relieve the spinal cord compression and restrict the excessive back drift, promote the neurological function recovery and reduce the incidence of C₅ palsy.
