Diseases or traumas involving the spine occasionally cause severe vertebral body collapse to result in either spinal instability or neural deficit, or both. In methods of treatment, conventional decompressive laminectomy results in neural improvement, but it can cause local instability of spine and lead progressive neural deficit. Vertebral stabilization by using bone cement(methylmethacrylate) provides immediate stabilization and avoids bulky external-fixation devices and external supports. We report two cases of thoracic spinal stabilization by using bone cement.
