目的：探讨椎弓根导航导板技术螺钉置入在严重脊柱侧凸手术中的应用效果。方法运用随机整群抽样的方法选取2013年1月至2014年9月收治的20例严重脊柱侧凸患者，依据随机数字表法将这些患者分为观察组和对照组，每组各10例。给予对照组患者传统徒手椎弓根螺钉植入术治疗，给予观察组患者导航导板技术椎弓根螺钉植入术治疗，然后对两组患者椎弓根螺钉植入情况、侧凸畸形矫正情况、手术时间、术中失血量、透视次数及并发症发生情况进行统计分析。结果观察组患者椎弓根螺钉植入的优良率100.0%（122/122）显著高于对照组79.2%（84/106）（P<0.05），侧凸畸形矫正率80.0%（8/10）显著高于对照组60%（6/10）（P<0.05），手术时间显著短于对照组（P<0.05），术中失血量和透视次数均显著少于对照组（P<0.05），术后并发症发生率10.0%（1/10）显著低于对照组50.0%（5/10）（P<0.05）。结论椎弓根导航导板技术螺钉置入在严重脊柱侧凸手术中具有较好的应用效果，值得在临床推广。%ObjectiveTo investigate the application Resultsof navigation of pedicle screw placement guide plate technology in severe scoliosis surgery.Methods20 cases of severe scoliosis who were treated from January 2013 to September 2014 were randomly selected by cluster sampling method,these patients were divided into observation group and control group according to the random number table,10 cases each. The control group were given traditional hand pedicle screw implantation treatment,the observation group were given navigation guide technology pedicle screw implantation therapy,then patients were compared with the conditions of the implanted pedicle screw,the rectifi cation of scoliosis,operative time, intraoperative blood loss,fl uoroscopy times and complications statistically.Results The superior pedicle screw implantation rate of observation group 100.0%(122/122)was signifi cantly higher than the control group 79.2%(84/106)(P<0.05),the scoliosis correction rate 80.0%(8/10)was signifi cantly higher than the control group 60%(6/10)(P<0.05),the operative time was signifi cantly shorter than the control group(P<0.05), the blood loss and intraoperative fluoroscopy times were significantly less than the control group(P<0.05),the postoperative complication rate 10.0%(1/10)was signifi cantly higher than the control group 50.0%(5/10)(P<0.05).Conclusion Pedicle screw placement navigation guides technology has better effect in severe scoliosis surgery,as is worthy of promotion in the clinical.
