This database is an independent database containing all variations of extradurale metastasis. The Research Lab has developed a special questionnaire for the surgeon to complete, aimed specifically at this patient group. The questionnaire is completed pre-operatively, ost- operatively and upon 6, 12 and 24 months follow-up visits. The patient does not complete an independent questionnaire.

The database contains patient information included retorspectively from 1992 to 1997, following this all patients are included pospectively. The number of metastatic surgery registerede today is approximately 500.
