摘要:

文题释义:
多节段脊髓型颈椎病:指发生3个或3个以上节段颈椎间盘退变、突出压迫脊髓与神经根等组织导致颈椎管狭窄,引起不同程度感觉及运动障碍的疾病,该病保守治疗不佳,以手术治疗为主。
颈椎矢状位平衡:指能够量化颈椎形态及力线改变的影像学参数,临床常用的有C2-7 Cobb角、C2-7矢状面轴向距离、T1倾斜角。

背景:颈椎后路单开门椎管扩大椎板成形(posterior single open-door laminoplasty,LAMP)及颈椎椎体次全切除植骨融合(anterior cervical corpectomy fusion,ACCF)均可有效治疗脊髓型颈椎病,但两种治疗方式对患者术后颈椎矢状位平衡有不同的影响。
目的:对比两种方法治疗多节段脊髓型颈椎病对颈椎矢状位平衡参数的影响。
方法:选择2017年8月至2020年8月蚌埠医学院第一附属医院收治的多节段脊髓型颈椎病患者70例,其中进行LAMP治疗30例,进行ACCF治疗40例。术前及术后随访时拍摄颈椎侧位X射线片,对比两组患者C2-7颈椎前凸角、C2-7矢状面轴向距离及T1倾斜角。试验获得蚌埠医学院第一附属医院伦理委员会批准。
结果与结论:①与术前比较,两组患者术后随访10个月的T1倾斜角无明显变化(P > 0.05);两组间术后10个月的T1倾斜角比较差异无显著性意义(P > 0.05);②与术前比较,ACCF组患者术后10个月的C2-7 Cobb角增大(P < 0.05),LAMP组患者术后10个月的C2-7 Cobb角减小(P < 0.05);ACCF组患者术后10个月的C2-7 Cobb角大于LAMP组(P < 0.05);③与术前比较,ACCF组患者术后10个月的C2-7矢状面轴向距离减少(P < 0.05),LAMP组患者术后10个月的C2-7矢状面轴向距离增加(P < 0.05);ACCF组患者术后10个月的C2-7矢状面轴向距离小于LAMP组(P < 0.05);④在ACCF组中,高T1倾斜角患者术后C2-7 Cobb角、C2-7矢状面轴向距离变化值与低T1倾斜角患者比较差异无显著性意义(P > 0.05);在LAMP组中,高T1倾斜角患者术后C2-7 Cobb角、C2-7矢状面轴向距离变化值均大于低T1倾斜角患者(P < 0.05);⑤结果表明,相较于LAMP,ACCF治疗多节段脊髓型颈椎病可以避免颈椎后凸畸形、更好地保持颈椎生理曲度、改善颈椎矢状位平衡;为了避免术后颈椎矢状位平衡失代偿,ACCF更适合高T1倾斜角脊髓型颈椎病的治疗。

Abstract: BACKGROUND: Posterior single open-door laminoplasty (LAMP) and anterior cervical corpectomy fusion (ACCF) can effectively treat cervical spondylotic myelopathy. However, the two treatments have different effects on the postoperative cervical spine sagittal balance.  
OBJECTIVE: To compare the effects of LAMP and ACCF on cervical sagittal balance parameters in the treatment of multilevel cervical spondylotic myelopathy.
METHODS:  Seventy patients with multilevel cervical spondylotic myelopathy in First Affiliated Hospital of Bengbu Medical College from August 2017 to August 2020 were enrolled in this study. There were 40 cases in ACCF group and 30 cases in LAMP group. Lateral cervical X-ray films were taken before operation and during follow-up. C2-7 Cobb angle, C2-7 sagittal vertical axis, and T1 inclination angle were compared between the two groups. This study was approved by the Ethics Committee of First Affiliated Hospital of Bengbu Medical College.  
RESULTS AND CONCLUSION: (1) Compared with preoperatively, there was no significant change in the T1 inclination angle between the two groups at 10 months after surgery (P > 0.05). There was no significant difference between the two groups in the T1 inclination angle at the 10-month postoperative period (P > 0.05). (2) Compared with preoperatively, the C2-7 Cobb angle of patients in the ACCF group increased at 10 months after surgery (P < 0.05), and the C2-7 Cobb angle of patients in the LAMP group decreased at 10 months after surgery (P < 0.05). The C2-7 Cobb angle of patients in the ACCF group was greater than that of the LAMP group at 10 months after surgery (P < 0.05). (3) Compared with preoperatively, C2-7 sagittal vertical axis in the ACCF group decreased at 10 months after the operation (P < 0.05), and C2-7 sagittal vertical axis increased in the LAMP group at 10 months after the operation (P < 0.05). The C2-7 sagittal vertical axis of the ACCF group was smaller than that of the LAMP group at 10 months after surgery (P < 0.05). (4) In the ACCF group, the postoperative C2-7 Cobb angle and C2-7 sagittal vertical axis changes in patients with high T1 inclination angle were not significantly different from those in patients with low T1 inclination angle (P > 0.05). In the LAMP group, the changes of C2-7 Cobb angle and C2-7 sagittal vertical axis in patients with high T1 inclination angle were greater than those in patients with low T1 inclination angle (P < 0.05). (5) The findings showed that compared with LAMP, ACCF in the treatment of multilevel cervical spondylotic myelopathy can avoid cervical kyphosis, better maintain the physiological curvature of the cervical spine and improve the sagittal balance of the cervical spine. To avoid postoperative sagittal balance decompensation of cervical vertebra, ACCF is more suitable than LAMP for the treatment of cervical spondylotic myelopathy with high T1 inclination angle.
