文题释义:
无骨折脱位型颈脊髓损伤:是一种特殊的颈脊髓损伤,是指X射线、CT等影像学检查提示无骨折脱位,但患者在临床上有脊髓损伤表现,占所有颈脊髓损伤的3%-16%,其临床表现可轻可重,绝大多数为非完全性脊髓损伤,本组51例患者全部为不完全性脊髓损伤。
无骨折脱位型颈脊髓损伤的治疗:目前针对成人无骨折脱位型颈脊髓损伤选择手术与非手术治疗,仍然存在分歧。有学者认为,成人颈脊髓损伤多为不完全性,合理的保守治疗即可不同程度地恢复脊髓神经功能,且手术有可能使原有的脊髓损伤加重。但非手术治疗往往不能取得令人满意的疗效。
 
摘要
背景:中老年人的颈椎可因不同原因导致不同程度的椎管狭窄,在受伤时发生无骨折脱位颈髓损伤概率也相对较高,有文献报道可占颈段脊髓损伤的3%-16%。
目的:探讨MRI在诊断和预测无骨折脱位型颈脊髓损伤预后中的作用,并分析手术效果的影响因素。

方法:回顾分析2014年8月至2016年6月就诊于淄博市中心医院的51例成人无骨折脱位型颈脊髓损伤患者,根据影像学资料,分别采取前路、后路或前-后路联合手术,将术中所见颈椎骨韧带损伤与MRI表现对比。使用单因素和多因素Logistic回归分析患者的年龄、外伤类别、脊髓损伤MRI类型、受伤到就诊时间、脊髓损伤信号长度、脊髓损伤ASIA分级、颈椎管狭窄程度、伤后8 h内是否使用激素治疗、受伤至手术的时间、手术方式等10个因素对预后的影响。

结果与结论:①颈椎MRI较术中所见更全面显示了脊髓及椎间盘韧带复合体损伤(χ2=5.966,P < 0.05),且颈脊髓损伤与相应椎间隙平面椎间盘韧带复合体损伤有关(χ2=1.53,P < 0.05);②单因素分析结果表明,脊髓损伤MRI类型、脊髓损伤信号长度、脊髓损伤ASIA分级、颈椎管狭窄程度、伤后8 h内是否使用激素治疗、受伤至手术时间与脊髓神经功能恢复相关(P < 0.1);③再经多因素Logistic回归分析,脊髓损伤MRI类型、脊髓损伤信号长度、颈椎管狭窄程度、受伤至手术时间与脊髓神经功能恢复有明显相关性(P < 0.05);④结果提示,颈椎MRI因其组织分辨优势,在诊断无骨折脱位型颈脊髓损伤及预测其预后中具有重要作用;脊髓损伤程度、颈椎管狭窄程度及手术时机是影响术后疗效的主要因素。

Abstract:

BACKGROUND: In the elderly, the cervical vertebrae will appear with different degrees of spinal stenosis caused by various factors. Notably, the incidence of cervical spinal cord injury without fracture or dislocation is high, accounting for 3%-16% of cervical spinal cord injury.

OBJECTIVE: To explore the efficacy of MRI in the diagnosis and prognosis of cervical spinal cord injury without fracture or dislocation, and to analyze the influencing factors for surgical effectiveness.
METHODS: Fifty-one patients with cervical spinal cord injury without fracture or dislocation in Zibo Central Hospital from August 2014 to June 2016 were analyzed retrospectively. All the patients underwent anterior, posteror, or anterior-posterior fusion, respectively, and then the intraoperative ligament injury and MRI images were compared. The age, injury type, spinal cord injury type revealed on MRI, time from injury to hospital, signal length of spinal cord injury, American Spinal injury Association grade, degree of cervical stenosis, whether hormone used or not within 8 hours after injury, time from injury to surgery, and surgical approaches were analyzed based on univariate analysis and multivariate analysis by Logistic regression analysis.
RESULTS AND CONCLUSION: (1) MRI showed more comprehensive damage of the spinal cord and intervertebral disc ligament complex than the intraoperative findings (χ2=5.966,P < 0.05), and the cervical spinal cord injury was related to the injury of the corresponding intervertebral disc ligament complex (χ2=1.53, P > 0.05). (2) Univariate analysis results showed that the spinal cord injury type revealed on MRI, signal length of spinal cord injury, American Spinal injury Association grade, degrees of cervical stenosis, whether hormone used or not within 8 hours after injury, and time from injury to surgery were related to the functional recovery of spinal cord (P < 0.01). (3) Multivariate analysis results indicated that the type revealed on MRI, signal length of spinal cord injury and degrees of cervical stenosis were significantly related to the functional recovery of spinal cord (P < 0.05). (4) These results suggest that MRI has a high tissue resolution, so it plays an important role in the diagnosis of cervical spinal cord injury without fracture or dislocation. Moreover, the degrees of spinal cord injury and spinal stenosis, as well as operation time are main factors for curative efficacy.
