摘　　要：目的分析颈椎前路椎间盘切除减压植骨融合术(ACDF)治疗单节段颈椎病术后邻近节段退变(ASD)的发病率及危险因素。方法回顾性分析2015年7月—2017年12月于我科行ACDF治疗单节段颈椎病病人60例的临床及影像学资料。结果术后随访2年,按照影像学评定标准,ASD的发病率为23.3%(14/60)。ASD组和无退变组病人性别、椎管直径比较差异无统计学意义(P>0.05);ASD组病人年龄大于无退变组,术后Cobb角和钢板距邻近椎间隙之间的距离(PDD)均小于无退变组,差异有显著意义(t=-8.12~2.83,P<0.05)。结论手术时年龄与ASD的发病率相关,PDD过小、颈椎生理曲度恢复不佳会导致ASD的发生。Objective To investigate the incidence rate of adjacent segment degeneration(ASD)after anterior cervical discectomy and fusion(ACDF)for single-segment cervical spondylosis and related risk factors.Methods A retrospective analysis was performed for the clinical and imaging data of 60 patients with single-segment cervical spondylosis who underwent ACDF in our department from July 2015 to December 2017.Results After 2 years of follow-up,the incidence rate of ASD was 23.3%(14/60)according to imaging evaluation criteria.There were no significant differences in sex and spinal canal diameter between the ASD group and the non-ASD group(P>0.05),and compared with the non-ASD group,the ASD group had a significantly older age and a significantly lower postoperative Cobb angle and plate-to-disc distance(PDD)(t=-8.12 to 2.83,P<0.05).Conclusion Age at the time of surgery is correlated with the incidence rate of AS,and small PDD and poor recovery of cervical physiological curvature can cause ASD.
