目的：分析老年症状性椎体压缩骨折患者邻近椎间盘的MRI信号改变及其临床意义。方法对60例老年症状性椎体压缩骨折患者（68个骨折椎体）邻近椎间盘的MRI表现进行回顾性分析。结果68个骨折椎体中48个椎体有邻近椎间盘损伤（71％）。48个有邻近间盘损伤的骨折椎体中27个椎间盘损伤位于骨折椎体上方（42％），16个骨折椎体同时有上下椎间盘损伤（50％），5个椎间盘损伤位于骨折椎体下方（8％）。在损伤的64个椎间盘中，1级（椎间盘水肿）占52%（33/64），2级（椎间盘出血/破裂）占39%（25/64），3级（椎间盘疝）占9%（6/64）。结论老年症状性椎体压缩骨折患者邻近椎间盘的MRI信号改变，能够揭示椎间盘损伤的病理生理变化，对临床诊断和治疗有指导意义。%Objective To analyze the variation characteristics and clinical signiifcance of magnetic resonance imaging (MRI) signals in intervertebral disc in elderly patients with symptomatic vertebral compression fractures. Methods 60 elderly patients with symptomatic vertebral compression fractures(68 fracture vertebral bodies)were examined by MRI. Results There were 48 vertebral bodies with intervertebral disc injury in 68 fracture vertebral bodies (71%). There were 27 intervertebral disc injury located above the fracture vertebral bodies in 48 vertebral bodies with intervertebral disc injury (42%), and 16 fracture vertebral bodies with upper and lower intervertebral disc injury (50%), and 5 intervertebral injuries located below the fracture vertebral bodies (8%). 64 injuried discs studied, 52%(33/64) were determined to be grade 1(disc edema), 39%(25/64) grade 2 (bleeding/rupture), and 9%(6/64) grade 3 (displacement). Conclusion The changes of MRI signals indicate the changes of pathophysiology in the intervertebral disc in elderly patients with symptomatic vertebral compression fractures. MRI is helpful in guiding the clinical diagnosis and treatment.
