Computer-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.
Seven 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.
At 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.
Navigation 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.
计算机辅助导航系统在退行性和创伤性脊柱手术中广泛用于椎弓根螺钉定位。在脊柱肿瘤手术中，其应用仍在发展，并且可扩展用于肿瘤识别和切除。本文的目的是介绍我们的经验。
2011年3月至10月，对7例选定患者（5例女性，2例男性）进行手术治疗，这些患者平均年龄44岁（最小17岁 - 最大62岁），患有原发性脊柱良性或恶性肿瘤或脊柱转移瘤，手术中使用了计算机辅助导航系统。
平均随访18个月（最小15个月 - 最大23个月），未观察到局部复发。仅1例因C1椎弓根螺钉位置不当需要进行翻修手术。
导航系统可提高螺钉置入、肿瘤定位和切除的手术准确性。必须考虑学习曲线和技术方面以避免潜在的严重错误。
