TOTAL SPONDYLECTOMY IN METASTASIZING OSTE OSARCOMA OF THE SPINE - A CASE-REPORT

We report on a case of a 28 year old male patient, on whom in 1984 a r otationplasty was performed, due to an osteogenic sarcoma of the left distal femur. Eight years after the incidence of the primary tumor, a metastasis of the osteogenic sarcoma in the twelfth thoracic vertebra occured. The tumor extended from the vertebral body to one pedicle and did not pass over the bony limits. After neoadjuvant chemotherapy an total spondylectomy was performed. Due to this method wide surgical ma rgins could be achieved. Up to now these margins could only be execute d with malignant bone tumors located in the extremities, whereas they could not be realized with the methods of spondylectomies, that were a lready introduced. By this case we want to present an innovative opera tion method for the treatment of primary malignant tumors or solitary metastasis of the spine, with the help of which we could give these pa tients a promising live expectancy.
