中文摘要：

目的 探究腰椎骨折损伤程度与骨折的分型、损伤评分、后凸畸形和神经功能损伤的关联。方法 将患者根据后方韧带复合体（PLC）损伤程度分为PLC完整组和PLC损伤组。通过评判两组患者的骨折分型、损伤评分、后凸畸形及神经功能损伤情况,研究他们与PLC损伤的关系。结果PLC损伤租的载荷分享评分系统（LCS）评分（7.1±0.8）分和严重程度评分（TLICS）（8.2±0.6）分均比PLC完整组的LCS评分（5.7±0.5）分和TLICS（4.6±0.7）分高。PLC损伤组患者的Denis分型和AO分型亦更严重。PLC损伤组的Cobb角为29°,PLC完整组的Cobb角为19°。PLC损伤组的神经功能不全比例89%,PLC完整组的这一比例为60%。结论 胸腰椎骨折与后方韧带复合体关系密切。PLC损伤程度与骨折分型、损伤评分、后凸畸形和神经损伤程度呈正相关的关系。

英文摘要：

Objective To investigate the association between the lumbar vertebral fracture damage degree with the fracture classification,injury score,kyphosis deformity and nerve function injury. Methods According to the damage degree of posterior lig- ament complex（PLC）,the patients were divided into the PLC intact group and PLC injury group. Its relationship with PLC injury was researched by evaluating the fracture classification,injury score and nerve function injury situation in the two groups. Results The LCS score and TLICS score in the PLC injury group were （7.1±0.8） points and （8.2±0.6） points,which were higher than （5.7±0.5） points and （4.6q-0.7） points in the PLC intact group. The Denis score in the PLC injury group was more serious. The Cobb angle in the PLC injury group was 29°, and which in the PLC intact group was 19~. The proportion Of nerve function insuffi- ciency in the PLC iniury group was 89 °, while which in the PLC intact group was only 60°. Conclusion The thoracolumhar ver- tebral fracture is closely related with PLC. PLC damage degree is positively correlated with the fracture classification,injury score, kyphosis deformity and nerve function injury degree.
