According to the first, intravertebral vacuum phenomenon is the result of vertebral osteonecrosis,8,14,17,18 whereas the second theory supports that intravertebral vacuum phenomenon signifies nonunion and pseudarthrosis of a vertebral fracture.20,21 A third theory, which did not find appeal, suggested that intravertebral gas could be of intradiskal origin, leaking to the vertebra through the fracture, since a high coincidence (86%) of intervertebral disk vacuum was noted in cases of intravertebral vacuum.6

第一种理论认为椎体内真空现象是椎体缺血性坏死的结果[8，14，17，18]，而第二个理论认为椎体内真空现象意为着骨不连和假关节[20，21]，另外目前还未广泛接受的第三个理论认为椎体内气体可能是从椎间盘中从椎体骨折裂隙中流入的，椎体内出现真空现象的同时伴有椎间盘内真空的比例很高（86％）[6]。
