摘要: 目的 比较Zina和Sextant微创椎弓根螺钉系统在无神经症状的不稳定型胸腰段骨折中的临床效果.方法 2013年1月至2014年4月共53例无神经损害的胸腰段单节段A型骨折患者采用经皮骨折复位内固定手术治疗, 其中Zina组30例, Sextant组23例, 记录并比较2组患者的为手术时间、术中出血量、术后引流量、术中X线暴露时间、住院费用、Cobb角、目测视觉类比评分法 (VAS评分) 、Oswestry功能障碍指数 (ODI) 及住院费用.结果 所有患者均随访1224个月 (平均16.9个月) , Zina组在手术时间、术中出血、X线暴露时间及住院费用均低于Sextant组, 2组之间有显著差异 (P<0.05) , 2组患者术后1周, 3个月及12个月测量的Cobb角度、VAS和ODI指数均较术前有明显改善 (P<0.05) , 但2组之间比较差异无统计学意义 (P>0.05) .结论2种微创椎弓根螺钉系统均能有效治疗胸腰段骨折, 但与Sextant系统相比, Zina系统手术时间更短, 术中出血更少, X线暴露和住院花费更低, 是一种更为理想的胸腰椎骨折治疗微创内固定系统.Abstract: Objective To compare the curative effect of Zina and Sextant screwing system in the treatment of thoracolumbar fracture.Methods A total of 53 patients included who underwent minimally invasive spine surgery for unstable thoracolumbar fracture without neurological deficit from Jan 2013 to Apr 2014.30 patients were treated with Zina system and 23 patients were treated with Sextant system.The two groups were compared in terms of perioperative indexes, Cobb angle, visual analogue scales (VAS) , Oswestry disability index (ODI) and hospitalization expenses.Results All patients were followed up for 1224 (mean, 16.9) months.Compare with Sextant group, Zina group had significantly shorter surgery time, less intraoperative X-ray exposure, blood loss and hospitalization expenses (P<0.05) .The cobb angle, VAS and ODI at one week, 3 and l 2 months after operation were significantly improved in all the patients (P<0.05) , but the differences between the two groups were not significant (P>0.05) .Conclusions The two minimally invasive pedicle screw systems are effective in the treatment of thoracolumbar fractures, but compared with the Sextant system, Zina system can shorten the operation time, reduce the intraoperative bleeding, X-ray exposure and hospitalization cost.Therefore, the Zina system may be preferable in the treatment of thoracolumbar fracture without neurological deficit.
