后路椎间盘镜联合可膨胀性椎间融合器B-twin置入椎间融合术治疗腰椎退行性疾病的临床应用

目的探讨后路椎间盘镜联合可膨胀性椎间融合器B-twin置入椎间融合术治疗腰椎退行性疾病的临床应用。方法 2005年6月~2009年8月,对43例腰椎退行性疾病患者行后路椎间盘镜联合可膨胀性椎间融合器B-twin置入椎间融合术。用日本骨科学会（Japanese Orthopaedics Association,JOA）评分改善率评价患者功能状态改善情况;用Suk标准判断患者融合情况;用Frankel分级评估患者神经功能改善情况。结果所有患者均获1年以上随访,随访12~28个月,平均18.5个月。JOA改善率在术后1周和术后1年时分别为81.3%、85.0%。患者术后1年融合率为91.3%。神经功能Frankel分级均有不同程度提高。结论后路椎间盘镜联合可膨胀性椎间融合器B-twin置入椎间融合术治疗腰椎退行性疾病具有创伤小、临床症状恢复可靠且植骨融合率高等优点。

Diskoscope and interbody fusion with inflatable B-twin for the treatment of lumbar degenerative disease

Objective To investigate the clinical application of diskoscope and interbody fusion with inflatable B-twin for the treatment of lumbar degenerative disease. Methods From June 2005 to August 2009, 43 patients with lumbar degenerative disease were treated by diskoscope and interbody fusion with inflatable B-twin. The Japanese Orthopaedics Association (JOA) improvement rate was used to evaluate the functional status. The Sue standard was used to evaluate fusion condition. The Frankel classification was used to evaluate the nerves function. Results All the patients were followed up for over 1 year. The follow-up period was 12-28 months,and the mean period was18.5 months. The JOA improvement rate was 81.3% at 1 week postoperative and 85.0% at 1 year postoperative. The fusion rate was 91.3% at 1 year postoperative. Frankel classification was increased at some degree. Conclusion Diskoscope and interbody fusion with inflatable B-twin for the treatment of lumbar degenerative disease has advantage of small trauma, high reliability of clinical symptoms recovery, and high fusion rate.
