脊柱真空现象临床研究进展

Spinal vacuum phenomenon: clinical relevance

脊柱真空现象（vacuum phenomenon,VP）是指发生在椎体、椎间盘、关节间隙和椎管内的气体积聚。1%~3%的正常成人可发现椎间盘真空现象,在腰腿痛的老年患者中检出率可达20%。产生脊柱真空现象的病因多样,其与脊柱相关症状的疾病有密切联系,主要诊断依据来源于影像学检查。本文通过近年来国内外对于脊柱真空现象的临床研究总结,分析引起脊柱真空现象的病因、临床表现及相关影像学特点,进而为临床上与该现象相关疾病的诊断与治疗提供积极的参考。

Spinal vacuum phenomenon is gas accumulation in the vertebral body,intervertebral disc,joint space and epidural space. 1% ~ 3% normal adults are with intervertebral vacuum phenomenon. Especially in the old patients with back-leg pain,this rate reaches up to about 20%. The pathogenesis of spinal vacuum phenomenon is varied and is associated with the correlative diseases. Imageological examination is the main evidences to diagnoze spinal vacuum phenomenon. This paper tries to summary the clinical progress of spinal vacuum phenomenon and analyze the pathogenesis,clinical manfestation and correlative image characteristics of spinal vacuum phenomenon so that can provide a positive reference for the diagnosis and treatment of spinal vacuum phenomenon.
