胸腰椎爆裂性骨折的诊断

Diagnosis of Thoracolumbar Burst Fractures

本文对114例120处胸腰椎爆裂性骨折进行回顾性分析。所有病例均摄胸腰椎X线片,94例行CT扫描,74例行MRI检查。结果共有27处骨折被误诊,占22.5％。作者认为,X线片常不能准确反映爆裂性骨折的病理特征,对于胸腰椎骨折应常规行CT扫描,必要时应同时行MRI检查,诊断中应注意将爆裂性骨折与压缩性骨折相鉴别。

One hundred and fourteen patients with 120 thoracolumbar burst fractures were retrospectively reviewed. Plain radiographs were available in all cases; CT scans and MRI were obtaines in 96 and 74 cases respectively. A total of 27 burst fractures were misdiagnosed as other types of fractures and accounted for 22.5% .The results showed that plain ra-diographs often fail to delineate the pathological features of thoracolumbar burst fractures.It suggested that CT should be routinely indicated and MRI examination, when necessory, may be simultaneously considered.For diagnosis, burst frac-tures should be differentiated from compressive fractures.
