Solis融合器在前路颈椎椎间融合术治疗邻椎病中的应用

Application of Solis fusion cage in anterior cervical intervertebral fusion for adjacent vertebral degeneration

目的探讨Solis融合器在前路颈椎椎间融合术治疗邻椎病(ASD)中的应用,总结其在颈椎前路术后ASD翻修术中的临床疗效、优势及缺点。方法回顾性分析2007年4月—2016年6月收治的使用Solis融合器行颈椎前路手术后需行翻修术的12例ASD患者的临床资料,记录手术时间、术中出血量,通过患者术前、术后日本骨科学会(JOA)评分、颈椎功能障碍指数(NDI)、吞咽困难情况等评估神经功能,结合手术前后X线片、CT及MRI影像学表现评估临床疗效。结果所有患者术后随访4～114(61.8±29.3)个月。术后JOA评分、NDI均较术前明显改善,差异具有统计学意义(P <0.05)。所有患者翻修术后均未出现吞咽困难等并发症,复查颈椎正侧位X线片均证实获得骨性融合。结论 Solis融合器应用在颈椎前路手术后ASD翻修术中安全有效,具有暴露范围小、手术时间短、对原手术节段无干扰、术后吞咽困难发生率低等优点。

Objective To explore the application of Solis fusion cage in anterior cervical intervertebral fusion for adjacent segment degeneration(ASD),and to summarize its clinical efficacy,advantages and disadvantages.Methods The clinical data of 12 patients with ASD who needed revision surgery after anterior cervical surgery with Solis fusion cage from April 2007 to June 2016 were analyzed retrospectively.The operation time,intraoperative bleeding volume,preoperative and postoperative Japanese Orthopaedic Association(JOA)scores,neck disability index(NDI)and dysphagia were recorded to evaluate neurological function.The clinical efficacy was evaluated by roentgenographs,CTs and MRIs before and after operation.Results All patients were followed up for 4-114(61.8±29.3)months.JOA score and NDI were significantly improved compared with those before operation,and the differences were statistically significant(P<0.05).No complications such as dysphagia were found in all patients after revision.Bone fusion was confirmed by roentgenographs.Conclusion Solis fusion cage is safe and effective in revision of ASD after anterior cervical spine surgery.It has the advantages of small exposure range,short operation time,no interference to the original operative segment and low incidence of dysphagia after operation.
