Ligation and partial excision of the cauda equina as part of a wide resection of vertebral osteosarcoma: a case report and description of surgical technique.

Abstract：

STUDY DESIGN:A case report. OBJECTIVES:To describe the unique challenges and novel surgical approach to treatment of vertebral osteosarcoma involving the dura as a margin. SUMMARY OF BACKGROUND DATA:Osteosarcoma of the vertebral column is a rare, malignant osseous tumor, carrying a poor prognosis. Currently, best available evidence supports that optimal surgical treatment entails wide excision of the tumor. Intentionally compromising neurologic function in order to ensure resection of the tumor with wide surgical margins can pose a difficult dilemma for the surgeon and patient. We describe here the first reported case, to our knowledge, of wide surgical resection of a vertebral osteosarcoma, including ligation and resection of part of the cauda equina and conus medullaris. METHODS:The clinical and radiographic presentations of a patient with osteosarcoma of L2 are presented. The challenges of surgical treatment of a primary malignant tumor of the spine, involving the dura as a margin, are discussed. The ultimate surgical technique employed to achieve wide surgical margins is described in detail. RESULTS:Four-year follow-up shows the patient is doing well, ambulating in a wheelchair, with no clinical or radiologic evidence of active disease or back or neuropathic pain and solid bony fusion. CONCLUSION:Currently, there is sufficient evidence to support the premise that the best chance for cure in sarcomas of the spine can be afforded through en bloc resection with negative margins. Neurologic forfeit in resection of spinal tumors, however, is usually at the root level, and this is the only case where such dramatic neurologic sacrifice was carried out. Although it is still early, the surgical and medical goals have been met, but most importantly, the patient's foremost goal of survival has been accomplished.
