This study aimed to evaluate the short- to medium-term outcomes of the second-generation Wallis interspinous dynamic stabilization device for treatment of lumbar degenerative disease.
Fifty patients with lumbar degenerative disease treated from August 2007 to September 2009 were included in this retrospective study. The Japanese Orthopedic Association (JOA) score and the Oswestry Disability Index (ODI) were used for therapeutic efficacy evaluation. Odom's criteria were used to evaluate postoperative outcome with regard to symptoms. Anteroposterior X-rays were obtained after surgery. All patients were followed up for 2 years.
Based on Odom's criteria, 22, 24 and 4 patients had excellent, good, and fair results respectively. The JOA score at 3, 12, and 24 months after surgery was significantly higher than before surgery (all p < 0.001), and the ODI score at 3, 12, and 24 months after surgery was significantly lower than before surgery (all p < 0.001). The posterior intervertebral disc height and the neural foramina height at 12 and 24 months after surgery was significantly higher than before surgery (both p < 0.001).
Implantation of the second-generation Wallis interspinous dynamic stabilization device produced satisfactory clinical outcome at short- and medium-term follow-up in patients with lumbar degenerative disease.
本研究旨在评估第二代Wallis棘突间动态稳定装置治疗腰椎退行性疾病的中短期疗效。
本回顾性研究纳入了2007年8月至2009年9月期间接受治疗的50例腰椎退行性疾病患者。采用日本骨科学会（JOA）评分和Oswestry功能障碍指数（ODI）评估治疗效果。采用Odom标准评估术后症状改善情况。术后拍摄前后位X线片。所有患者均随访2年。
根据Odom标准，分别有22例、24例和4例患者获得优、良和可的结果。术后3个月、12个月和24个月时的JOA评分显著高于术前（均p<0.001），术后3个月、12个月和24个月时的ODI评分显著低于术前（均p<0.001）。术后12个月和24个月时的椎间隙后缘高度和神经孔高度显著高于术前（均p<0.001）。
第二代Wallis棘突间动态稳定装置植入术在腰椎退行性疾病患者的短期和中期随访中产生了满意的临床效果。
