摘要
目的评估弹性固定在腰椎椎间融合的可行性及其临床价值。方法 2011年9月-2013年3月根据入选标准选择12例患有腰椎退行性疾病的患者,男4例,女8例;年龄40~62岁,平均52.9岁。在行腰椎融合术时采用弹性固定。评价指标包括视觉模拟评分（VAS）法、术前功能障碍指数（ODI）评分及其改善率、椎间隙高度的变化、椎间植骨融合率、椎间骨痂形成的情况、患者满意度及临床成功率。结果所有患者均获得随访。术后各随访时间点的VAS评分及ODI评分改善分数与术前的差异有统计学意义（P〈0.05）。腰椎CT示大量的骨痂形成,全部患者均融合。无内固定物断裂、松动和移位。结论弹性固定适用于腰椎椎间融合,为腰椎退行性疾病的治疗提供更多的选择。
Objective To assess the feasibility and clinical value of lumbar elastic fixation through the clinical research of elastic fixation for lumbar intervertebral fusion. Methods According to the criteria, we selected 12 patients with lumbar degenerative disease diagnosed between September 2011 and March 2013 as our study subjects. Among them, 8 were females, and 4 were males, aged between 40 and 62 years old, averaging 52.9 years. Elastic fixation was adopted in the lumbar fusion. Evaluation indicators included visual analogue scale （VAS） scores, Oswestry disability index （ODI） score and its rate of improvement, intervertebral height changes, the rate of intervertebral fusion, intervertebral bone callus formation, patient satisfaction and clinical success rate. Results All patients were followed up. During various postoperative follow-up points, VAS score and ODI score improved significantly （P 〈 0.05）. A large amount of callus formation was shown in lumbar CT. No fracture, loosened or shifted internal fixation occurred. Conclusion Elastic fixation for lumbar intervertebral fusion provides another choice for the treatment of lumbar degenerative disease.
