[Surgical management of thoracolumbar spinal sarcoma].

Primary malignant tumors of the thoracolumbar spine are very rare. The most common entities are chordoma, followed by osteosarcoma, Ewing's sarcoma and chondrosarcoma. Detailed imaging and a sequential biopsy are the most important diagnostic steps. The surgical staging system of Weinstein and Boriani permits a precise analysis of tumor expansion. Therapy under a multimodal concept consists of (neo-) adjuvant therapy and possible radiation. The surgical therapy should be performed as an en bloc excision with sufficient resection borders. The reconstruction of the defects must include methods of vertebral body replacement and long posterior instrumentation. En bloc spondylectomy is a very demanding technique and demands strict indications, close cooperation with adjacent specialties and exact planning of the operation. Only in this manner is the operation possible and offers the only sufficient form of resection. The execution of the en bloc spondylectomy should be left to spine centers with great experience, as they could also guarantee the respective complication management.
