摘要
目的探讨USS钉棒系统内固定结合椎体间植骨融合术治疗退行性腰椎不稳症的疗效。方法对78例退行性腰椎不稳症患者采用USS钉棒系统内固定结合椎体间植骨融合术治疗。采用Oswestry功能障碍指数与JOA下腰痛评分对患者手术前和术后1年随访期进行评分;摄片观察植骨融合情况并统计术后内固定失败（钉棒松动、折断）的发生率。结果 6例术后出现顽固轻微手术区胀痛。所有患者均得到随访,时间13~36个月。术后3个月患者腰背痛明显缓解,术后半年基本可以恢复正常日常生活。随访期内无钉棒松动、折断发生。术后6~8个月骨性融合。术后1年,Oswestry功能障碍指数较低,JOA下腰痛评分较高,与术前比较差异有统计学意义（P〈0.05）。腰椎功能改善总有效率达100%。结论 USS钉棒系统内固定结合椎体间植骨融合术治疗退行性腰椎不稳症临床疗效满意。
Objective To investigate the clinical effects of USS screw-rods system with lumbar interbody fusion in patients with degenerative lumbar intervertebral instability.Methods Clinical data of 78 patients with degenerative lumbar intervertebral instability which were performed USS screw-rods system with lumbar interbody fusion were analyzed retrospectively.Oswestry disability index and score of Japanese orthopaedic association（JOA）were recorded in preoperatively and the 1st year postoperatively respectively.X-ray films were made to observe fusion and internal fixation failure rate.Results 6 patients had slight swelling pain in operative area.All the cases have been followed up for 13 to 36 months.The back pain improved obviously in all patients in the 3rd month postoperatively and they regained normal life in the 6th month postoperatively.All patients achieved successful radiographic fusion in the 6th to 8th month postoperatively and hadn′t internal fixation failure.Oswestry disability index was lower and score of JOA was higher postoperatively and there were significant difference compared with the one preoperatively（P0.05）.The total effective rate was 100 percent.Conclusions The clinical effect of USS screw-rods system with lumbar interbody fusion in patients with degenerative lumbar intervertebral instability is satisfactory.
