Total cervical spondylectomy for primary osteogenic sarcoma. Case report and description of operative technique.
The authors describe a technique for total spondylectomy for lesions involving the cervical spine. The method involves separately staged anterior and posterior approaches and befits the unique anatomy of the cervical spine. The procedure is described in detail, with the aid of radiographs, intraoperative photographs, and illustrations. Unlike in the thoracic and lumbar spine--for which methods of total en bloc spondylectomy have previously been described--a strictly en bloc resection is not possible in the cervical spine because of the need to preserve the vertebral arteries and the nerve roots supplying the upper limbs. Although the resection described in this case is by definition intralesional, it is oncologically sound, given the development of effective neoadjuvent chemotherapeutic regimens for osteosarcoma.
