文题释义:
Cobb角:脊柱侧弯的严重程度多通过对侧弯曲角度的测量得以评估,而角度测量最常采用的是 Cobb 角度测量方法。用于测量的X 线片为脊柱标准全长的正位相。若Cobb角< 25°,无需治疗,每隔4-6个月随访一次,进行动态观察;若25° < Cobb角< 45°,建议手术治疗。
脊柱侧凸:俗称脊柱侧弯,它是一种脊柱的三维畸形,包括冠状位、矢状位和轴位上的序列异常。
 
摘要
背景:后路切开椎弓根钉内固定是临床胸腰椎骨折的主要修复方式之一,但其存在术中创伤大、出血多、术中及固定后康复时间长,部分患者固定后长期存在顽固性腰背部僵硬与腰痛的缺陷。经皮椎弓根螺钉进行脊柱骨折外固定时,可减少置钉对椎旁肌的过度损伤,尤其对单纯前中柱损伤的急性胸腰椎压缩性骨折的修复效果较好。为此,试验假设以微创后路经皮椎弓根螺钉内固定修复单纯前中柱损伤的急性胸腰椎骨折有较好的疗效。
目的:回顾性分析微创后路经皮椎弓根螺钉内固定修复单纯前中柱损伤的急性胸腰椎骨折的疗效。
方法:研究为回顾性、单中心、自身前后对照的临床试验,在中国河南省,郑州市第153中心医院完成。纳入试验的单纯前中柱损伤的急性胸腰椎骨折患者共32例,平均34.7岁,男22例,女10例,均采用微创后路经皮椎弓根螺钉内固定修复,随访3个月。试验的主要观察指标为固定前、固定后即刻、固定后3个月患者的伤椎的Cobb角,以观察胸腰椎弯曲程度。试验的次要观察指标为固定前、固定后即刻、末次随访患者的伤椎前缘高度、X射线片形态以评价胸腰椎骨折的恢复情况;患者手术时间、术中出血量、住院时间;其他观察指标为固定后3个月患者不良反应发生率。试验经中国河南省郑州市第153中心医院伦理委员会批准。研究符合世界医学会制定的《赫尔辛基宣言》的要求。参与者对治疗方案和过程均知情同意,并签署知情同意书。试验于2016年11月10日在北美临床试验注册中心作回顾性分析注册(NCT02963571)。
讨论:试验旨在证实微创后路经皮椎弓根螺钉内固定治疗单纯前中柱损伤的急性胸腰椎骨折具有确切疗效,并提供长期随访的客观数据。

Abstract:

BACKGROUND: Posterior pedicle screw fixation is commonly used for thoracolumbar fracture. However, associated disadvantages include severe trauma, extensive bleeding, long rehabilitation time, and long postoperative duration of intractable lumbar stiffness and low back pain. Percutaneous pedicle screw external fixation can reduce injury caused by screw insertion into the paraspinal muscles; particularly in acute thoracolumbar vertebral compression fracture with simple anterior spinal column injury. We hypothesized that minimally invasive posterior percutaneous pedicle screw fixation for acute thoracolumbar vertebral fractures with simple anterior spinal column injury would exhibit good curative effects.

OBJECTIVE: To retrospectively analyze the curative effects of minimally invasive posterior percutaneous pedicle screw fixation on acute thoracolumbar vertebral fractures with simple anterior spinal column injury.
METHODS: This retrospective, single-center, self-controlled trial was performed in PLA 153 Central Hospital, Zhengzhou, Henan Province, China. Thirty-two patients with acute thoracolumbar vertebral fracture with simple anterior spinal column injury (22 males and 10 females, average age 34.7 years, range 25-47 years) were included. All patients underwent minimally invasive posterior percutaneous pedicle screw internal fixation and were followed up for 3 months. The primary outcome measure was the Cobb angle of the injured vertebral body before, immediately after, and 3 months after internal fixation, which was used to investigate the change in the thoracolumbar spine curvature. The secondary outcome measures included: the anterior height of the injured vertebral body and radiographic findings before and immediately after internal fixation and at the last follow-up (to evaluate the recovery of thoracolumbar vertebral fracture), operation time, intraoperative blood loss, duration of hospitalization, and incidence of adverse events 3 months after internal fixation. The study protocol had been approved by the Ethics Committee of PLA 153 Central Hospital, China and was performed in strict accordance with the Declaration of Helsinki developed by the World Medical Association. Signed informed consent regarding study protocol and treatments had been obtained from each patient. Trial registration: ClinicalTrial.gov identifier: NCT02963571; registered on November 10, 2016.
DISCUSSION: This study aims to validate the curative effects of minimally invasive posterior percutaneous pedicle screw fixation in acute thoracolumbar vertebral fractures with simple anterior spinal column injury, and provide objective long-term follow-up data for future studies.
