Metastatic lesions are the most common spinal extradural tumours. Significant advances in their neurosurgical management have been made in the last two decades. This retrospective study was undertaken to summarise the long-term results of surgery and the outcome of patients with cervical spine metastases. Sixty-two patients with cervical spine metastases who underwent instrumented spinal surgery at a single centre in an 12-year period (1989-2000) were analysed. All patients presented with local pain and with either neurological deficits, spinal instability, or a combination of both. A standard anterior approach to the cervical spine was chosen, and a partial or total vertebrectomy and vertebral body replacement with subsequent anterior instrumented fusion were carried out in all cases. General and neurological status was evaluated at baseline and in regular intervals thereafter. Plain X-rays, CT, and MRI were used for preoperative planning. Postoperative follow-up was done by X-rays. The mean follow-up time for all patients was 1.5 years. A stable bony fusion of the cervical spine was achieved in 60 patients (96.8%), with two additional patients needing a further procedure for maintaining the mechanical stability of the spine. There was mild early surgery-related morbidity, and no mortality. The most frequent temporary surgery-related side effect was reversible vocal cord paresis in 5 cases (8.0%). There were 3 cases (4.8%) of early instrumentation failure. One of these was symptomatic and underwent second-look surgery. No late complications occurred due to instrumentation hardware failure. The 1-year survival rate of all patients after surgery was 58%, and the 2-year survival rate was 21%. Our results demonstrate that surgical removal of extradural metastases with subsequent instrumented fusion is a low-morbidity and low-complications procedure with high rates of permanent stabilisation of the compromised cervical spine. In addition, it improves the neurological deficits and relieves the local pain in a significant proportion of patients. Excellent local control of malignant disease can be achieved by the surgical procedure aided by subsequent local and systemic adjuvant therapy. Overall survival time and prognosis of the patients, however, are mainly depending on the type and the stage of the primary malignancy.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
