title: [Vertebral osteonecrosis and percutaneous vertebroplasty].
abstract: Vertebral osteonecrosis is characterized by the presence of the intravertebral vacuum phenomenon. It is a relatively uncommon disease and although it may be caused by different pathologies, the most frequent cause is posttraumatic. The explanation for the presence of intravertebral gas is not known completely. We present the case of a 74-year-old patient who after suffering a vertebral traumatism, to complain of intense vertebral pain. A simple radiological study, CT scan, and magnetic resonance confirmed the presence of intravertebral vacuum phenomenon. We studied this radiological sign and then commented on its evolution after percutaneous vertebroplasty.
