摘要
目的对腰椎融合术后出现邻近节段退变(adjacent segment degeneration,ASD)的临床研究现状进行综述。方法查阅近年关于腰椎融合术后出现ASD的概念、发生率、相关影响因素和预防等方面的文献,并进行综述。结果 ASD的概念包括影像学ASD和临床症状ASD,腰椎融合术后影像学ASD发生率可达8%～100%,临床症状ASD发生率为5.2%～18.5%。ASD的发生与个体因素(年龄、性别、术前情况等)和手术因素(融合节段长短、融合术式、内固定使用、矢状面平衡、椎间隙过度撑开等)相关。术中减少融合节段、维持矢状面平衡以及非融合技术的应用可预防ASD的发生。结论腰椎融合术后ASD发生率增高。非融合技术的应用降低了ASD的发生率,取得了较好的近期临床效果,但也存在一些并发症,其中长期效果尚待进一步研究。
Objective To review the present clinical research situation of ad）acent segment degeneration （ASD） after lumbar spinal fusion. Methods The recent literature concerning ASD in the concept, the incidence, the risk factors, and prevention was reviewed. Results The concept of ASD includes radiographic ASD and clinical ASD. The incidences of radiographic ASD and clinical ASD were 8%-100% and 5.2%-18.5%, respectively. The risk factors for ASD include both patient and surgical factors. Patient factors include age, gender, preoperative condition, and so on. Surgical factors include the length of the fusion, mode of fusion, internal fixator, sagittal balance, excessive distraction of disc space, and so on. It can prevent ASD to reduce the length of the fusion, to keep sagittal balance, and to use the non-fusion technology. Conclusion Many researches have proved that the incidence of ASD is increased after lumbar spinal fusion, and it can be reduced by the non-fusion technology. Non-fusion technology has obtained good short-term results. But the ｜on,-term resnlt~ ~hn.lrl h,. fiwth,.~ ,~h A K ~. 1：~^.：__~
