MULTIPLE VERTEBRAL FRACTURES AT THE “DR. MANUEL DUFOO” SPINE CLINIC

ABSTRACT Objective: To establish the frequency of presentation of multiple vertebral fractures and evaluate the relationship between the postsurgical condition and the initial neurological lesion, as well as to report the associated injuries in this group of patients. Methods: We conducted a review of patients with spinal trauma and a diagnosis of multiple vertebral fractures who were admitted to the “Dr. Manuel Dufoo Olvera” Spine Clinic of the Secretary of Health of Mexico City from January 1,2014 to June 30, 2017. The multiple fractures were classified as either contiguous or non-contiguous, according to the number of vertebral bodies and levels affected. The statistical analysis was conducted using formulas of descriptive statistics and the information was then tabulated and graphed to assess the relationship between the anatomical classification and the degree of neurological injury. Results: We observed 530 patients, of whom 47 met the criteria. Thirty-one (65.95%) of the cases corresponded to contiguous fractures and 16 cases (34.05%) to non-contiguous fractures. Fourteen patients (29.78%) with neurological integrity were classified as ASIA D, 20 patients (42.58%) with complete lesion as ASIA A, 7 seven patients (14.89%) as ASIA B, and 6 patients (12.76%) with partial injury as ASIA C. Conclusions: The correlation between the classification of vertebral injuries and the presence of neurological lesion did not show significant differences between contiguous and non-contiguous fractures. Level of Evidence II; Retrospective.

摘要
研究目的：明确多发椎体骨折的就诊频率，评估术后状态与初始神经损伤的关联，并报告该类患者的合并损伤情况。
研究方法：回顾性分析2014年1月1日至2017年6月30日期间，墨西哥城卫生部“曼努埃尔·杜福·奥尔维拉博士”脊柱诊所收治的脊柱创伤合并多发椎体骨折患者。根据受累椎体数量及节段，将多发骨折分为连续性与非连续性两类。采用描述性统计方法开展数据分析，随后通过制表与绘图，评估解剖分型与神经损伤程度的相关性。
研究结果：共筛查530例患者，其中47例符合纳入标准。31例（65.95%）为连续性多发椎体骨折，16例（34.05%）为非连续性多发椎体骨折。14例（29.78%）神经功能完整的患者被归为美国脊髓损伤协会（ASIA）D级；20例（42.58%）完全性损伤患者为ASIA A级，7例（14.89%）为ASIA B级，6例（12.76%）部分损伤患者为ASIA C级。
研究结论：椎体损伤分型与神经损伤存在相关性，但连续性与非连续性骨折组间未呈现显著差异。证据等级：Ⅱ级；研究类型：回顾性研究。
