后方韧带复合体完整性在胸腰椎骨折中的临床意义

目的 探讨胸腰椎骨折中后方韧带复合体（PLC）完整性的临床意义。方法 回顾性分析自2008-07-2012-12收治的93例胸腰椎骨折,根据临床查体结合影像资料将其分为PLC完整组41例与PLC损伤组52例。结果 与PLC完整组相比,PLC损伤组的Denis分型与AO分型分布有明显区别。PLC损伤组中LCS评分、LSC〉7分比例、TLICS评分、TLICS〉5分比例、除外PLC项目的 TLICS评分、Cobb角度与PLC完整组相比差异有统计学意义（P〈0.05）;2组的年龄、性别及椎管占位率之间对比差异无统计学意义（P〉0.05）。PLC损伤组神经功能ASIA分级较PLC完整组更重。结论 PLC的完整性是评估胸腰椎骨折损伤程度的重要指标,其与骨折的分型、损伤评分、后凸畸形及神经功能损伤等方面密切相关。

Clinical significance of posterior Hgamentous complex integrity in thoracic and lumbar spine fractures

Objective To investigate the clinical significance of posterior ligamentous complex （PLC） integrity in the patientswith thoracic and lumbar spine fractures. Methods Between July 2008 to December 2012, 93 patients with thoracic andlumbar fractures were retrospectively analyzed. According to the clinical examinations and imaging findings, these cases wereclassified to PLC intact group（n=41） and PLC injured group（n =52）. Results The disbution of Denis and AO classificationswere different between the PLC intact and PLC injured groups. The LSC score, TLICS score, Cobb angle and ASIAneurological injury scale were significantly severer in the PLC injured greup（P 〈0.05）. There were no significant differences inthe gender, age and ratio of spinal canal stenosis between the two groups （P 〉0.05）. Conclusion The integrity of PLC is animportant factor in the evaluation of severity for thoracic and lumbar spine fractures. PLC injury is associated with fractureclassification, severity score, kyphosis and neurologie function.
