摘要
目的探讨撑开型椎间融合器治疗腰椎不稳症的临床疗效。方法采用Oswestry功能障碍指数(Oswestry Disability Index,ODI)对患者术前、术后症状进行评定,测量患者术前、术后椎间隙前凸角度及动力位片椎体间角度活动域,观察融合率和并发症。结果ODI评分:术后优良率和末次随访优良率分别为90.1%和93.5%。随访时间6～18个月(平均11个月),随访率100%,融合率100%。融合节段椎间隙前凸角度5.2°±1.5°,动力位片术前椎间活动域为20.5°±1.5°,术后椎间活动域为4.5°±0.5°,两者差异有统计学意义(P<0.01)。无融合器脱出、塌陷、移位等并发症。结论撑开型椎间融合器治疗腰椎不稳症,具有手术简单、创伤小和疗效好等优点。
Objective To explore the clinical effect of expandable interbody fusion cage （EIFC） on treating lumbar spine instability syndrome（LSIS）. Methods The clinical effect was evaluated with the Oswestry disability index （ODI）, including the symptom of pre-operation and post-operation, the lumbar interbedy lordosis angle, domain of saglttal rotation of the intetbody on X-ray, fusion rate and complications. Results According to the ODI, excellent rates were 90.1% （post-operation） and 93.5% （the last follow-up）. All were followed up from 6 months to 18 months and fusion rate was 100%. Lumbar interbody lordosis angle was 5.2°±1.5°. The dynamic domain of sagittal rotation of pre-operation was 20.5°± 1.5° and post-operation 4.5°±1.5° There is statistical significance（ P 〈0.01）. No complication with interbody fusion cage prolapse, sink and dislocation was happened. Conclusion Apphcation of EIFC to treat LSIS is simple mini-invasive surgery and has good clinical outcome.
