摘　　要：目的:探究椎体成形手术前后椎体压缩性骨折的低场MRI信号特点跟术后疗效的相关性。方法:对36例椎体压缩性骨折行椎体成形术患者的临床资料与影像学资料进行回顾性分析,按骨髓水肿在MRI所见分为3组,治疗组(12例)为骨髓完全水肿患者;观察组(12例)为部分骨髓水肿患者;对照组(12例)为无骨髓水肿受检者;观察3组患者手术前后功能障碍指数的评价以及视觉模拟疼痛评分。结果:术前3组患者视觉疼痛模拟评分差异无统计学意义(P>0.05),术后数据对比,差异具有统计学意义(P<0.05);各组椎体成形术前后数据差异具有统计学意义(P<0.05);术前3组患者功能障碍指数差异无统计学意义(P>0.05),术后数据对比,差异具有统计学意义(P<0.05);各组椎体成形术前后数据差异具有统计学意义(P<0.05)。结论:椎体成形术治疗压缩性椎体骨折疗效显著;低场磁共振信号所显示的骨髓水肿情况可以对该病患者的治疗效果进行一定程度的预测,对比无骨髓水肿和有骨髓水肿患者的临床疗效,有骨髓水肿患者的效果较好,受累椎体骨髓水肿范围越大,椎体成形术临床疼痛缓解的程度越好。Objective： To explore the correlation between the characteristics of low field MRI signal of vertebral compression fracture and the effect after percutaneous vertebral angioplasty .Method： The clinical and imaging data of 36 patients with vertebral lesions undergoing vertebroplasty were analyzed retrospectively , they were divided into three groups according to the degree and scope of MRI bone marrow edema , 12 cases with complete bone marrow edema in the treatment group , and 12 patients with partial bone marrow edema in the observation group, and 12 patients without bone marrow edema in the control group .The conditions of pre-operative and postoperative surgery dysfunction indexes and visual analog pain scores of patients in there groups were observed.Result： There was no significant difference preoperative visual analog pain scores of pa -tients in three groups （P〉0.05）, but the differences in postoperative data of patients in three groups were sig -nificant （P〈0.05）.The differences in preoperative and post -operative vertebroplasties of patients in three groups were statistically significant （P〈0.05）.The differences in preoperative dysfunction indexes of patients in three groups were not significant （P〉0.05）, and the comparison in postoperative data were significant （P〈0.05）.The differences in pre -operative and post -operative vertebroplasties of patients in three groups were statistically significant （P〈0.05）.Conclusion： Compressive vertebroplasty vertebral fracture delivers signifi -cant efficacy, and low-field MRI signal characteristics poses certain degree of predictive value on their effica -cies, clinical efficacy of non-bone marrow edema is better when compared to that of bone marrow edema , and the degree of clinical pain relief of vertebroplasty is better , while greater scope of non-bone marrow edema is.
