经皮椎间孔镜技术治疗椎间隙感染的疗效

Efficacy of percutaneous transforaminal endoscopic technique in the treatment of patients with intervertebral space infection

目的评价经皮椎间孔镜技术治疗椎间隙感染的临床效果。方法应用经皮椎间孔镜技术治疗椎间隙感染14例。采用视觉模拟评分法（VAS）评估并分析患者手术前和手术后1d、2周、1个月、3个月时腰腿疼痛的情况。采用改良MacNab评分评估患者治疗后10个月时的疗效。结果与术前比较患者手术后各设计时点的VAS显著降低，差异有统计学意义（P〈0．05）。治疗后10个月优效率为92．8％（13／14例），良效率7．1％（1／14例），优良率100％（14／14例）。结论经皮椎间孔镜技术治疗椎间隙感染临床疗效肯定。

Objective To assess the clinical efficacy of transforaminal endoscopic spine system in the treatment of patients with lumbar spondylodiscitis. Methods Fourteen patients with lumbar spondylodiscitis were treated by transforaminal endoscopic spine system. VAS was evaluated before and 1 d, 2 weeks, 1 month, 3 months after the treatment. The efficacy based on the modified MacNab criteria was observed at 10 months after the treatment. Results Compared with pretreatment, the VAS of all designed time points after the treatment was significantly lower （P 〈 0.05 ）. The recovery rate was 100% （ 14/14 cases）; the excellent and good effect rates were 92.8% （13/14 cases） and 7.1% （1/13 cases） at 10 months after the treatment respectively. Conclusion Percutaneous transforaminal endoscopic technique is a kind of effective way in the treatment of patients with intervertebral space infection.
