To evaluate therapeutic effects of Wallis interspinous dynamic stabilization in treating ASD after lumbar spinal fusion.
Totally 40 patients (included 16 males and 24 females, aged 25 to 60 years old) with degenerative disc disease were treated with posterior interbody fusion. Among them, 20 cases (treatment group) were treated with posterior interbody fusion combined with Wallis interspinous dynamic stabilization, while other 20 cases (control group) only treated with posterior interbody fusion. JOA score and VAS score were compared after inserted Wallis interspinous dynamic stabilization at 1 month and 3 years, and changes of intervertebral disc height of adjacent segment and cross-sectional area of the canal were tested and compared.
All patients were followed up from 3 to 5 years with an average of 3.6 years. All injuries were healed at stage I and the pain were released after treatment. There were no significant meaning in JOA score and VAS score at 1 month after treatment between two groups (P>0.05), while had meaning at 3 years (P<0.05). There were no statistical significane in intervertebral disc height of adjacent segment and cross-sectional area of the canal at 1 month after treatment (P>0.05), while had statistical meaning at 3 years (P<0.05).
There is no difference in immediate effects between two groups. Both of them can obtain good results for effective decompression. Medial-term effectiveness of treatment group is obviously better than control group, which depends on Wallis interspinous dynamic stabilization to plays good biology effects and effective accelerate adjacent degeneration caused by lumbar fusion.
评估Wallis棘突间动态稳定系统在腰椎融合术后治疗邻椎病（ASD）的疗效。
对40例退行性椎间盘疾病患者行后路椎间融合术治疗，其中男16例，女24例，年龄25～60岁。其中20例（治疗组）采用后路椎间融合联合Wallis棘突间动态稳定系统治疗，另外20例（对照组）仅采用后路椎间融合术治疗。于植入Wallis棘突间动态稳定系统后1个月及3年比较两组的日本骨科协会（JOA）评分和视觉模拟评分（VAS），并检测比较相邻节段椎间盘高度及椎管截面积的变化。
所有患者随访3～5年，平均3.6年。所有损伤均Ⅰ期愈合，术后疼痛缓解。两组术后1个月时JOA评分和VAS评分比较差异无统计学意义（P>0.05），术后3年时有统计学意义（P<0.05）。两组术后1个月时相邻节段椎间盘高度及椎管截面积比较差异无统计学意义（P>0.05），术后3年时有统计学意义（P<0.05）。
两组近期疗效无差异，均能有效减压获得良好效果。治疗组中期疗效明显优于对照组，这依赖于Wallis棘突间动态稳定系统发挥良好生物学效应，有效延缓腰椎融合所致的邻椎退变。
