中文摘要:

目的:对漏斗技术和徒手技术在胸椎弓根螺钉置入中的准确性和安全性进行对比研究。

方法:采用8具胸椎标本,男性5具,女性3具;年龄57~82岁,平均68岁。随机分为2组,每组4具,利用漏斗技术和徒手技术分别进行椎弓根螺钉置入,然后CT扫描判断置入是否成功,对两种方法的成功率和危险性穿破率进行统计学对比分析。

结果:漏斗技术置入96枚螺钉中成功84枚,徒手技术置入96枚中成功73枚,两种方法成功率比较,差异有统计学意义(P<0.05).漏斗技术危险性穿破2枚,徒手技术危险性穿破9枚,两种方法危险性穿破率比较,差异有统计学意义(P<0.05).

结论:“漏斗技术”具有简单、经济、安全和实用等优点,可以减少神经根和硬膜囊的损伤机会。

Comparison of accuracy of pedicle screw placement in the thoracic spine using funnel technique and free hand technique
ABSTRACT  

Objective: To study the accuracy the pedicle screw placement in the thoracic spine using funnel technique and free hand technique.

Methods: Eight cadavers including 5 males and 3 females were analysed. The age ranged from 57 to 82 years(mean 68 years). Cadawers were randomly assigned to one of two instrumentation groups. In four cadavers,“funnel technique” was used for screw placement. In the remaining four cadavers,free hand technique then was used. Success of pedicle screw placement was judged by CT scan. The rate of success of two ways was compared using statistic analysis.

Results: Ninety-six screws were inserted by“funnel technique” and free hand technique respectively,84 of “funnel technique” were successed,and 73 of free hand technique were successed. Significant differences were found between two ways (P<0.05). Chanciness tresis occurrenced in“funnel technique” on 2 screws and free hand technique on 9 screws. There were significant differences in rates of chanciness tresis(P<0.05).

Conclusion: Funnel technique is simple,safe and cost-effective alternative to any other thchnique for pedicle screw placement in thoracic spine,funnel technique is able to reduce the chance of critical injury of nerve root and dura.
