OBJECTIVE
To assess the value of ultrasonographic imaging of the posterior ligamentous complex (PLC) to diagnose ligamentous injuries, in patients with mild thoracolumbar fractures.
METHODS
Patients with thoracolumbar fractures were included in this prospective study. Patients underwent palpation of the midline of the back, and ultrasonography was performed over the entire thoracolumbar region by an experienced sonographer. A team that included a musculoskeletal radiologist, an orthopaedic surgeon and a sonographer assessed the ultrasound results. Ultrasonographic and magnetic resonance imaging (MRI) findings were jointly evaluated in a subgroup of patients who were able to fund MRI analysis. Conflicts regarding the results were resolved by a majority vote.
RESULTS
A total of 21 patients participated in the study, all of whom exhibited abnormal ultrasonographic echogenicity on the supraspinous or interspinous ligaments. Three patients were diagnosed with a rupture of the supraspinous ligament. In 15/17 (88.2%) patients, interspinous ligament injuries were detected caudally to the injured vertebrae.
CONCLUSIONS
Ultrasound examination is a reliable complementary diagnostic tool to identify PLC injuries in patients with mild thoracolumbar fractures.
目的
评估超声成像对诊断轻度胸腰椎骨折患者后韧带复合体（PLC）损伤的价值。
方法
胸腰椎骨折患者纳入本前瞻性研究。患者接受背部中线触诊，由经验丰富的超声检查人员对整个胸腰椎区域进行超声检查。由一名肌肉骨骼放射科医生、一名骨科医生和一名超声检查人员组成的团队评估超声检查结果。在能够进行磁共振成像（MRI）分析的患者亚组中，联合评估超声和MRI检查结果。结果存在的分歧通过多数表决解决。
结果
共有21例患者参与研究，所有患者的棘上韧带或棘间韧带均表现出异常超声回声。3例患者被诊断为棘上韧带断裂。在17例患者中的15例（88.2%）中，在受伤椎体尾侧检测到棘间韧带损伤。
结论
超声检查是识别轻度胸腰椎骨折患者PLC损伤的可靠辅助诊断工具。
