文题释义:

光辅助X射线体表定位:近年来该方法在骨折植入物内固定中得到应用,与传统定位、导航方法相比优势较多,对植入物内固定定位、导航时装置结构相对比较简单,技术上对于专业的医学设备要求相对较低,能适应不同种类复杂的骨折类型。同时,该方法能够动态化进行体表定位,为不同骨折的内固定提供更加准确的定位和导航,避免对骨折部位反复透视,减少机体产生放射性损伤,缩短患者骨折愈合时间。
参照物法导航定位:参照物法比较简单,它是在体表放置金属、颜料等能够显影的物体,辅助X射线以及CT等技术进行体表定位。该固定方法能够获取病灶的准确位置。但是,对于软组织内能够游走的异物而言,该定位导航方法难以准确确定其具体位置,临床上缺乏动态的体表定位技术。
 
摘要
背景:传统骨科内固定时主要采用C臂机完成体表定位,但是C臂机对人体产生的损伤较大,固定时间较长,增加患者痛苦。
目的:探讨光辅助X射线体表定位在骨科植入物内固定中定位、导航中的应用及效果。
方法:26只新西兰大白兔随机分为C臂机组和光辅助X射线体表定位组,每组13只。2组大白兔均模拟软组织异物定位、骨折髓内钉远端锁钉置入、脊柱椎弓根螺钉进针点定位3种内固定方法,C臂机组采用C臂机进行定位导航,光辅助X射线体表定位组采用X射线进行定位导航,比较2组定位方法对大白兔内固定置入的定位、导航效果。
结果与结论:①与C臂机组相比,光辅助X射线体表定位组在软组织异物定位、骨折髓内钉远端锁钉置入以及脊柱椎弓根螺钉进针点定位中定位导航所需要的时间显著缩短(P < 0.05),位移及角度偏差显著减小(P < 0.05);②结果表明,采用X射线对骨科内固定物进行定位操作方法相对简单,实用性较高,能获得较高的性价比,能提高内固定物置入准确性,缩短固定时间。

Abstract:

BACKGROUND: The traditional orthopedic fixation by C-arm positioning surface is completed, but the large C-arm injury on the human body and the long fixed time increase the suffering of patients.

OBJECTIVE: To investigate the X-ray fixed in position within the orthopedic implants, navigation and effect.
METHODS: Twenty-six New Zealand white rabbits were randomly divided into C-arm machine group and X-ray group, with 13 in each group. Rabbits in both groups were used to simulate soft tissue foreign body localization, intramedullary nail implantation at distal fracture end and spinal pedicle screw entry point position. In the C-arm machine group, positioning navigation was conducted with C-arm machine. In the X-ray group, X-ray positioning navigation was used. The positioning and navigation effects were compared between the two groups. 

RESULTS AND CONCLUSION: (1) Compared with the C-arm machine group, the time required for navigation in the X-ray group targeting soft tissue foreign body localization, fracture distal locking intramedullary nail implantation and pedicle screw spinal needle point location was significantly shorter (P < 0.05); navigation displacement and deviation produced were significantly less (P < 0.05). (2) These findings suggested that the X-ray positioning for orthopedic fixation method is relatively simple, with high availability, and can obtain a high performance-price ratio. Meanwhile, the X-ray localization can improve accuracy and shorten the fixed time.
