[Spinal metastases and metastasis-induced pathological fractures of the spine].

The vertebral column is a common site of metastatic disease to the bone. The incidence is very high and varies with tumor type. Radiation therapy is effective in the treatment of most cases of spinal metastases. Pathologic fractures of the vertebral body occur in 30-50% of the patients affected, indicating an operative intervention. The ultimate aim of the operation is to increase the patients' quality of life. The tumor mass is normally located in the vertebral body. Therefore, only with an anterior approach can excellent decompression of the spinal cord and reduction of the tumorous tissue be achieved. In patients with advanced metastatic disease, however, in whom an anterior approach is not practicable, tumor decompression may be accomplished through a costotransversectomy combined with posterior stabilization of the spine. Laminectomy is rarely indicated, and then for posteriorly located tumor tissue, and should be combined with dorsal stabilization of the spine. With reference to a few actual cases, we present the approaches and stabilization methods currently in use at our clinic.
