目的通过分析下颈椎外伤分级评分(SLIC)系统的影像学表现,探讨SLIC评分系统对指导下颈椎损伤患者治疗方式选择的意义。方法回顾性分析2006-11—2014-10临床确诊并行MDCT检查的下颈椎外伤40例,对影像学资料的MDCT和MRI检查进行SLIC评分。本研究中40例治疗时未参考SLIC评分系统,其中非手术治疗15例,手术治疗25例。结果非手术组15例,SLIC评分0~5(1.07±1.16)分,14例SLIC评分<4分;DLC可疑损伤5例,撕裂者1例;神经状态均完好。手术组25例,SLIC评分1~10(5.68±2.06)分,22例SLIC评分≥4分;DLC损伤19例,可疑损伤4例,完好2例;临床神经体征正常10例,神经根受累5例,完全脊髓损伤3例,不全脊髓损伤1例,不全脊髓损伤伴脊髓进行性压迫6例。手术组SLIC评分明显高于非手术组,差异有统计学意义(χ2=29.122,P<0.001)。结论 SLIC评分系统对临床上下颈椎损伤患者治疗方式的选择具有明确的指导意义。
Objective To analyze the imaging manifestations of the lower cervical spine injury grading system (SLIC) to explore the significance of the SLIC scoring system in selecting the treatment modalities for patients with cervical spine injury. Methods A retrospective analysis of 40 cases of lower cervical spine injuries clinically diagnosed concurrently with MDCT during 2006-11-2014-10 was performed. The SLIC scores of MDCT and MRI were analyzed. In this study, 40 patients without reference SLIC scoring system, including non-surgical treatment of 15 cases, 25 cases of surgical treatment. Results In non-operation group, 15 cases had SLIC score of 0 ~ 5 (1.07 ± 1.16), 14 SLIC score of 4, DLC suspicious lesion of 5, and tear of 1 patient. All the neurological status were intact. SLIC score was 1 ~ 10 (5.68 ± 2.06) in 22 cases, SLIC score was 22 in 4 cases, DLC was diagnosed in 19 cases, suspicious lesion in 4 cases and intact in 2 cases. There were 10 cases with normal clinical signs of nerve and 5 cases with nerve root involvement Cases, complete spinal cord injury in 3 cases, incomplete spinal cord injury in 1 case, incomplete spinal cord injury with spinal cord compression in 6 cases. The SLIC score of operation group was significantly higher than that of non-operation group (χ2 = 29.122, P <0.001). Conclusion The SLIC scoring system has clear guiding significance for the choice of treatment modalities in patients with upper and lower cervical spine injuries.
