PurposeComputer-assisted navigation systems are largely used for pedicle screws positioning in degenerative and traumatic spine surgery. In oncologic spine surgery its use is still developing and could be extended for tumor identification and excision. Aim of this paper is to present our experience.MethodsSeven selected patients (5 females, 2 males), mean age 44 years (min 17-max 62) affected by primary benign or malignant tumors of the spine or spine metastases were surgically treated with the use of computer-assisted navigation system from March to October 2011.ResultsAt 18 months mean F.U. (min 15-max 23), no LR were observed. Revision surgery was necessary only in one case for C1 pedicle screw malpositioning.ConclusionsNavigation system can improve surgical accuracy in screws placement and tumor localization and excision. Learning curve and technical aspects must be considered to avoid potential serious mistakes.
