We believe that en bloc resection with a wide margin is the ideal treatment for any osteosarcoma; however, this procedure is very difficult to perform for an osteosarcoma of the spine because of the proximity of the spinal cord and the major vessels. Because it is difficult to excise the spinal tumor completely7,9, the prognosis after treatment of an osteosarcoma of the spine continues to be poor compared with that after treatment of an osteosarcoma in an extremity.
We report the case of a patient who was managed successfully with total en bloc spondylectomy10,11 for a primary osteosarcoma of the spine involving the eleventh . . . [Full Text of this Article]
