One of the major clinical issues encountered after lumbar spinal fusion is the development of adjacent segment pathology (ASP) caused by increased mechanical stress at adjacent segments, and resulting in various radiographic changes and clinical symptoms. This condition may require surgical intervention. The incidence of ASP varies with both the definition and methodology adopted in individual studies; various risk factors for this condition have been identified, although a significant controversy still exists regarding their significance. Motion-preserving devices have been developed, and some studies have shown their efficacy of preventing ASP. Surgeons should be aware of the risk factors of ASP when planning a surgery, and accordingly counsel their patients preoperatively.
腰椎融合术后遇到的主要临床问题之一是相邻节段病变（ASP）的发生，这是由相邻节段机械应力增加所致，并导致各种影像学改变和临床症状。这种情况可能需要手术干预。ASP的发生率因各研究采用的定义和方法而异；虽然关于其重要性仍存在重大争议，但已确定了该病症的各种风险因素。已研发出保留运动功能的器械，一些研究显示了它们预防ASP的效果。外科医生在规划手术时应了解ASP的风险因素，并据此在术前向患者提供咨询。
