【摘要】：目的:探讨颈后路双开门椎管减压扩大成形术中使用内固定(LA椎板夹)对于多阶段的颈椎后纵韧带骨化症(OPLL)的疗效及预后效果分析。方法:回顾性研究2013-2015行颈后路双开门椎管减压扩大成形术治疗多节段颈椎后纵韧带骨化症患者26例,其中男22例,女4例,年龄42-77岁,平均56.4岁,平均随访时间13个月,患者术前全部常规行颈椎X线正侧位及过伸过屈位片、CT平扫加矢状位重建及MRI检查。临床疗效使用日本骨科学会(JOA)来评分以及影像学检查评估,并计算手术前后颈椎CT平扫狭窄层面的椎管有效矢状径,计算椎管矢状径改善率。在MRI图像上评价术前脊髓受压节段的压迫程度评分以及脊髓线(SC线)分型,并分析术后脊髓减压程度和SC线分型的关系。采用SPSS17.0统计分析软件用于统计分析,P0.05差异具有显著性。结果:26例患者均顺利完成手术,进行随访研究后发现,LA椎板夹用于颈椎后路双开门椎管减压扩大成形术取得了令人满意的疗效。JOA评分改善率55%,I型SC线者术后减压满意,术前脊髓压迫评分平均3.77±0.42分,术后平均1.13±0.34分;Ⅱ型者术后得到大部分减压,术前平均3.86±0.35分,术后平均2.73±0.46分;III型者减压不满意,术前平均4.00±0.00分,术后平均3.64±0.50分,比较差异均有统计学意义(P0.05)。结论:LA椎板夹用于颈后路双开门椎管减压扩大成形术治疗OPLL疗效满意,能够有效的改善脊髓压迫程度,提高患者的生活质量,改善预后。
[Abstract]:Aim: to evaluate the efficacy and prognosis of internal fixation (LA lamina clamp) in the treatment of multistage ossification of the posterior longitudinal ligament of cervical spine (OPLL). Methods: twenty-six patients (22 males and 4 females) with ossification of the posterior longitudinal ligament of the cervical spine were treated with posterior cervical decompression and open-door laminoplasty in 2013 / 2015. The mean age was 56.4 years (n = 42), with a mean age of 56.4 years (n = 42). The mean follow-up time was 13 months. All patients underwent X-ray and over-extension flexion X-ray, CT plain scan plus sagittal reconstruction and MRI examination before operation. The clinical efficacy was evaluated by the Japanese Orthopaedics Society (JOA), and the effective sagittal diameter of the spinal canal was calculated by CT before and after the operation, and the improvement rate of the sagittal diameter of the spinal canal was calculated. The score of compression degree and the classification of spinal cord line (SC line) were evaluated on MRI images, and the relationship between the degree of spinal cord decompression after operation and the classification of SC line was analyzed. SPSS17.0 statistical analysis software was used for statistical analysis, P0.05 significant difference. Results: all the 26 patients successfully completed the operation. The follow-up study showed that the LA laminae clip was used to expand the decompression of the posterior cervical vertebrae with double-door decompression. The improvement rate of JOA score was 55%, and the improvement rate of JOA score was 55%. The spinal cord compression score was 3.77 卤0.42 before operation and 1.13 卤0.34 after operation. Most of the patients with type 鈪，
