Surgical management of metastatic tumors of the cervical spine.
To present the results from the clinical presentation, the imaging diagnostics, surgery and postoperative status of 17 patients with cervical spine metastases, to analyse all data and make the respective conclusions and compare them with the available data in the literature.



The study analysed data obtained by patients with metastatic cervical tumours treated in St George University Hospital over a period of seven years. All patients underwent diagnostic imaging tests which included, separately or in combination, cervical x-rays, computed tomography scan and magnetic-resonance imaging. Severity of neurological damage and its pre- and postoperative state was graded according to the Frankel Scale. For staging and operating performance we used the Tomita scale and Harrington classification.



Seven patients had only one affected vertebra, 4 patients--two vertebrae, one patient--three vertebrae, 2 patients--four vertebrae, and in the other 3 patients more than one segment was affected. Surgery was performed in 12 patients. One level anterior corpectomy was performed in 6 patients, three patients had two-level surgery, and one patient--three-level corpectomy; in the remaining 2 cases we used posterior approach in surgery. Complete corpectomy was performed in 4 patients, subtotal corpectomy was used in 6 patients and partial--in 2 patients. Anterior stabilization system ADD plus (Ulrich GmbH & Co. KG, Ulm, Germany) was implanted in 2 patients; in 8 patients anterior titanium plate and bone graft were used, and in 1 patient--posterior cervical stabilization system.



Because of the pronounced pain syndrome and frequent neurological lesions as a result of the cervical spine metastases use of surgery is justified. The main purpose is to maximize tumor resection, achieve optimal spinal cord and nerve root decompression and stabilize the affected segment.
