目的探讨SUMMIT枕颈(SUMMIT Occipito-Cervical,SUMMIT OC)内固定系统在上颈椎骨肿瘤切除术后枕颈稳定性重建中的作用和价值。方法2004年10月~2006年9月本院对16例患者进行了上颈椎骨肿瘤切除后SUMMIT枕颈内固定术,术后随访6~30个月,平均19个月。结果未出现神经血管损伤及内固定松动、断裂、移位等并发症。术后头颈位置保持良好,植骨均于术后3个月达到骨性愈合。1例出现脑脊液漏,经换药术后2周愈合。结论SUMMIT OC内固定系统在上颈椎骨肿瘤切除术后能够有效的维持枕颈部的即刻稳定,便于患者早期下床活动,提高患者生活质量,有利于枕颈植骨块融合。安装方便,适合在上颈椎骨肿瘤切除术后应用。
Objective To investigate the role and value of the SUMMIT Occipito-Cervical (SUMMIT OC) fixation system in reconstructing the stability of the occipital neck after upper cervical spine tumor resection. Methods From October 2004 to September 2006, 16 patients underwent upper cervical vertebra resection and SUMMIT occipital internal fixation after operation. The patients were followed up for 6 to 30 months with an average of 19 months. The results did not appear neurovascular injury and internal fixation loosening, rupture, displacement and other complications. After head and neck position to maintain a good bone graft at 3 months after bone healing. 1 case of cerebrospinal fluid leakage, healing after 2 weeks after dressing change. Conclusions SUMMIT OC internal fixation system can effectively maintain the immediate stability of the occiput and neck after the resection of the upper cervical spine tumor, facilitate the patients to get out of bed early and improve their quality of life, which is good for the fusion of the occipital and cervical bone graft. Easy installation, suitable for use in the removal of upper cervical spine tumors.
