内固定技术在椎管肿瘤切除中的应用

目的探讨内固定技术在椎管肿瘤切除手术中的作用。方法回顾性分析2016年10月至2019年4月采用内固定技术结合显微手术治疗21例椎管肿瘤的临床资料,在神经电生理监测下,利用显微手术技术切除椎管肿瘤,然后利用内固定技术维持脊柱稳定性。结果 21例肿瘤中,19例完全切除,2例近全切除,1例术后复发,1例转移至三脑室内;术后患者均无神经功能损伤加重情况发生,内固定时无神经、脊髓、血管损伤;术后无感染,随访无内固定松动、断裂、脱落等情况发生,95.2%达到骨性融合。结论内固定技术结合显微外科手术,能在切除椎管肿瘤的同时,维持脊柱的稳定性,对于扩大暴露范围及保护脊髓神经功能方面均有帮助。

Application of internal fixation in resection of spinal canal tumors

Objective To investigate the role of internal fixation in resection of spinal canal tumors.Methods A retrospective analysis was performed on the clinical data of 21 patients with spinal canal tumors who were treated by internal fixation combined with microsurgery from October 2016 to April 2019. The spinal canal tumors were removed by microsurgery under neurophysiological monitoring, and the spinal stability was maintained by internal fixation.Results Among the 21 tumor cases, 19 had a total resection, 2 had a near-total resection, 1 had a postoperative recurrence, and 1 had a metastasis to the third ventricle. There were no aggravation of neurological function injury after surgery, injury of nerves, spinal cord, and blood vessels during internal fixation, postoperative infection, or loosening, rupture, and disarticulation of internal fixation during follow-up. Ninety-five point two percent of the cases achieved an osseous fusion.Conclusions Internal fixation combined with microsurgery can resect spinal canal tumors and maintain spinal stability, which is helpful in expanding exposure area and protecting spinal nerve function.
