[Elektronische Daten] [Shang-Wen Feng, Ming-Chau Chang, Hung-Ta Wu, Jung-Kuang Yu, Shih-Tien Wang, Chien-Lin Liu] We retrospectively reviewed plain radiographs from patients with four different diseases that can cause vertebral collapse: osteoporotic vertebral collapse, spinal infection, spinal metastasis, and multiple myeloma. The objective of the study was to find the percentages of intravertebral vacuum phenomena and vertebral collapse rates in the four groups. The vacuum phenomenon is often observed in osteoporotic compression fractures. However, these phenomena are rarely seen in spinal infection and malignant lesions. Whether the vacuum phenomenon is a benign indicator is not known. We retrospectively reviewed plain radiographs from four groups of patients, including 328 osteoporotic vertebral collapse patients, 317 spinal infection patients, 302 spinal metastasis patients, and 325 multiple myeloma patients. The pattern and occurrence rates of intravertebral vacuum phenomena and vertebral body collapse were analyzed. The occurrence rate of intravertebral vacuum phenomena in patients with osteoporotic vertebral collapse was approximately 18.9%. Only one case of intravertebral vacuum phenomena was observed in patients with spinal infection. Vacuum phenomena were not observed in patients with spinal metastasis. The occurrence rate of intravertebral vacuum phenomena in patients with multiple myeloma was 6.4%. The patterns of intravertebral vacuum phenomena were also analyzed. Intravertebral vacuum phenomena are common in patients with osteoporotic vertebral collapse. Most cases of intravertebral vacuum phenomena are of a benign nature. Moreover, intravertebral vacuum phenomena occur extremely rarely in patients with spinal infection. Such phenomena are also found in patients with multiple myeloma.
