研究目的:

比较颈前路与后路手术治疗华山影像学分型I型的急性成人无骨折脱位型颈脊髓损伤术后1年的神经功能恢复情况(ASIA运动评分)。评估围手术期指标(手术时间、术中出血量、术后引流量、术后住院天数)和手术相关并发症(并发症种类及发生率);对比其他神经功能指标(ASIA感觉评分和JOA评分);生活质量(NDI指数、SF-12评分)和影像学指标(颈椎曲度、活动度、融合、脊髓高信号、脊髓最大受压程度、椎管最大狭窄程度)的改善与转归。  

Objectives of Study:

A comparative study was conducted to evaluate the one-year neurological recovery (assessed by ASIA motor scores) following anterior versus posterior surgical approaches for the treatment of acute cervical spinal cord injury without fracture-dislocation in adults, classified as Type I in the Huashan radiological classification system. The assessment included perioperative parameters (operation time, intraoperative blood loss, postoperative drainage volume, and length of postoperative hospital stay) and surgery-related complications (types and incidency). Additional comparisons were made regarding other neurological function indicators (ASIA sensory scores and JOA scores), quality of life measures (NDI index and SF-12 scores), as well as imaging outcomes including cervical curvature, range of motion, fusion status, spinal cord high signal intensity, maximum degree of spinal cord compression, and maximum degree of spinal canal stenosis.

随机方法(请说明由何人用什么方法产生随机序列):

分层区组随机分配:按中心分层,通过中央随机化系统生成分配序列,固定区组大小,确保各中心比例均衡

Randomization Procedure (please state who generates the random number sequence and by what method):

Stratified block randomization: Stratified by center, allocation sequences are generated through a central randomization system (Interactive Web Response System), with fixed block sizes, ensuring a balanced ratio across centers.

Calculated Results after the Study Completed public access:

公开/Public

盲法:

本研究采用单盲设计。由于在实际操作中难以对患者及手术医师进行盲法,因此仅对评价者实施盲法。在完成随机分组后,所有结局指标的测量和评估分析均由对研究参与者分组信息不知情的第三方研究人员独立进行;评估数据录入和统计分析的过程也由未参与干预实施的专门人员完成,以尽量减少评估和分析环节的主观偏倚。

Blinding:

This study adopts a single-blind design. Due to the difficulty in blinding patients and the operating surgeons in actual practice, blinding is only implemented for the evaluators. After the randomization process, all outcome measures and evaluations are independently conducted by third-party researchers who are unaware of the participants' group assignments; the processes of data entry and statistical analysis are also carried out by dedicated personnel who did not participate in the intervention implementation, in order to minimize subjective biases in the assessment and analysis phases.
