目的使用超声检查对轻微胸腰段骨折患者脊柱后方韧带复合体(PLC)进行评估,了解超声对脊柱PLC的诊断意义和其影像学特点.方法对21名诊断为胸腰段骨折的患者胸腰段PLC进行超声检查,检查结果由包括2名脊柱外科医师和1名超声医师组成,对超声影像资料进行评估,同时对比相应患者超声影像与核磁影像差异.结果 21名患者韧间/棘上韧带内均发现异常回声,其中3名患者被诊断为棘上韧带断裂；85.7％的患者在损伤椎体棘突远端发现棘间韧带血肿信号,其中6名患者同时行核磁检查,结果发现超声检查的敏感度和特异度均优于核磁检查.结论超声对脊柱PLC的检查结果清晰可靠,同时简便易行,通过对诊断标准进行详细分类,可以成为胸腰段骨折患者后方韧带符合体诊断的“金标准”.

Objective To assess predictive value of ultrasound diagnostics to posterior ligamentous complex (PLC) in patients with mild thoracolumbar fracture.Methods Twenty-one candidates were selected,and ultrasound examination was performed over the whole thoracolumbar region by an experienced sonographer.A team included 2 orthopedic surgeons and one sonographer to process the ultrasound assessment information.The findings of ultrasound and MRI were evaluated respectively,and conflicts in results were decided by a majority vote.Results Abnormal echo in SSL or ISL under ultrasound evaluation was detected in all the 21 patients.Three cases were diagnosed as having rupture of supraspinous ligament.85.7％ ISL injuries were detected caudally to the injured veterbrae.Among the 6 patients undergoing MRI examination simultaneously,sensitivity and specificity of ultrasound examination were higher than MRI examination.Conclusion Ultrasound can be a reliable diagnostic method to PLC in patients with mild thoracolumbar fracture.With its high sensitivity and feasibility,ultrasound can be used as an alternative golden standard in PLC injury diagnosis.
