文题释义:
脊髓型颈椎病:是由于颈椎椎骨间连接结构退变,如椎间盘突出、后纵韧带骨化、黄韧带肥厚或钙化、钩椎关节增生及椎体后缘骨刺,导致脊髓受压或脊髓缺血,继而出现的脊髓功能障碍。
椎管扩大成形:是通过将椎板一侧全切断,另侧仅切断椎板外板,造成骨折及移位而扩大椎板矢状径,从而获得减压目的,临床上较常应用的术式有:单开门式椎管成形、双开门式椎管成形术、Z形成形、单椎板切除椎管成形及棘突悬吊等。
 
摘要
背景:目前有关后路椎板切除螺钉内固定与椎管扩大成形治疗多节段脊髓型颈椎病疗效比较的文献较多,但研究的样本量存在局限,对于两者的优缺点缺乏客观评价。
目的:系统评价后路椎板切除螺钉内固定与椎管扩大成形治疗多节段脊髓型颈椎病的临床疗效与安全性。
方法:应用计算机检索PubMed、Cochrane Central、EMbase、the ISI Web of Knowledge Database、CMB、CNKI、维普及万方数据库,纳入关于后路椎板切除内固定与椎管扩大成形治疗多节段脊髓型颈椎病疗效比较的随机或非随机对照试验。采用Rev-Man 5.3软件对两种治疗的术后JOA评分、术后颈椎活动度、术后颈椎曲度指数、术后C5神经根麻痹发生率及术后轴性症状发生率进行Meta分析。
结果与结论:①共纳入14篇研究,1 024例患者,其中椎板切除螺钉内固定组519例,椎管扩大成形组505例;②Meta分析结果显示,椎板切除螺钉内固定组C5神经根麻痹发生率高于椎管扩大成形组[RR=2.24,95%CI(1.33,3.75),Z=3.05,P < 0.05],术后颈椎活动度低于椎管扩大成形组[SMD=-0.71,95%CI(-2.21,-1.2),Z=6.63,P < 0.05];两组术后JOA评分、颈椎曲度指数、轴性症状发生率比较差异无显著性意义;③结果提示,后路椎板切除螺钉内固定与椎管扩大成形治疗多节段脊髓型颈椎病均有一定疗效,但后路椎管扩大成形对颈椎活动功能损伤小且术后C5神经根麻痹的发生率低,有一定优势,但在临床诊疗过程中仍需结合患者病情综合判断,其远期的疗效有待更进一步的临床研究。

Abstract:

BACKGROUND: Many studies concern the comparison of posterior laminectomy and instrumented fusion and posterior laminoplasty for multilevel cervical spondylotic myelopathy, but the sample size of many studies has limitations. There is lack of objective evaluation on advantages and disadvantages of two surgical methods.

OBJECTIVE: To compare the efficacy and safety of posterior laminectomy and instrumented fusion and laminoplasty in the treatment of multilevel cervical spondylotic myelopathy.
METHODS: A systematic search of all the studies published was conducted on the PubMed, Cochrane Central, EMbase, the ISI Web of Knowledge Database, CMB, CNKI, VIP and Wanfang databases. Randomized and non-randomized controlled trials that compared between posterior laminectomy and instrumented fusion and laminoplasty for multilevel cervical spondylotic myelopathy were identified. Meta-analyses were performed in postoperative Japanese Orthopaedic Association scores, cervical range of motion, cervical curvature index, incidence of C5 nerve root paralysis and incidence of axial symptoms.
RESULTS AND CONCLUSION: (1) Fourteen studies involving 1 024 patients were included. Among the patients, 519 underwent laminectomy and instrumented fusion and 505 underwent laminoplasty. (2) The results of the meta-analysis indicated that, compared with laminectomy and instrumented fusion group, laminoplasty group had advantages of a lower incidence of C5 palsy [RR=2.24, 95%CI(1.33,3.75), Z=3.05, P < 0.05] and small degree of cervical rotation injury [SMD=-0.71, 95%CI(-2.21,-1.2), Z=6.63, P < 0.05]. However, the two groups had no statistical difference in postoperative Japanese Orthopaedic Association score, cervical curvature index and the incidence of axial symptoms. (3) These results suggested that both laminectomy and instrumented fusion and laminoplasty were demonstrated to be effective for multilevel cervical spondylotic myelopathy. Laminoplasty had obvious advantages of decreasing the degree of cervical rotation injury and lowering incidence of C5 palsy. However, in the process of clinical diagnosis and treatment, the patient’s condition should be combined. The long-term clinical efficacy of the technology needs more clinical work to confirm.
