文题释义:
胫骨平台骨折:胫骨平台是机体膝关节最为重要的部位,其承受的负荷相对较大,骨折多为关节内骨折,患者发病后受到的力也相对复杂,如轴向力、侧向力或者不同力的混合。同时,胫骨平台骨折相对复杂,临床表现也不尽相同,并且与膝关节受伤所处的位置,如伸直、外翻、内翻等关系密切。
多层螺旋CT:它融合了计算机技术、图像处理技术、医学物理等学科与医学的交叉融合,其目的是利用各种医学影像数据,采用多平面重组、容积再现等三维图像重建方法,能为医生提供极具真实感和沉浸感的虚拟影像资料,清晰的显示骨折位置,了解不同骨关节之间的相互联系,从而能更加清晰、准确的了解置钉的具体位置。
 
摘要
背景:目前胫骨平台骨折治疗过程中置钉时缺乏理想的导航定位方法。相关研究显示,多层螺旋CT重建影像在复杂性胫骨平台骨折置钉导航定位中效果理想,但是尚未得到证实。
目的:探讨多层螺旋CT重建影像在复杂性胫骨平台骨折置钉导航定位中的应用效果。
方法:选择郑州大学第五附属医院2014年11月至2015年12月收治的80例复杂性胫骨平台骨折患者资料进行研究,均采用空心钉结合髓内钉内固定治疗,随机分为2组,每组40例。X射线组采用X射线置钉导航定位,螺旋CT组采用多层螺旋CT重建影像置钉导航定位。通过比较2组患者的骨折修复效果评估多层螺旋CT重建影像的置钉导航定位作用。
结果与结论:①螺旋CT组骨折部位、骨折粉碎程度、骨折移位情况以及骨缺损程度的满意度评分均显著高于X射线组(P < 0.05);②螺旋CT组患者采用多层螺旋CT定位导航过程中的手术时间、出血量、术后引流量均显著少于X射线组(P < 0.05);③螺旋CT组一次螺置钉成功率显著高于X射线组(P < 0.05);螺旋CT组置钉2次以上者显著少于X射线组(P < 0.05);④螺旋CT组手术后并发症发生率为8%,显著低于对照组的18%(P < 0.05);⑤结果提示,多层螺旋CT重建影像在复杂性胫骨平台骨折置钉中导航效果理想,能确定置钉的准确位置并进行导航,从而准确置入螺钉,提高治愈率,促进复杂性胫骨平台骨折的早期恢复。

Abstract:

BACKGROUND: At present, it lacks the ideal pedicle screws navigation method during screw placement for tibial plateau fractures. Related research showed that: multislice spiral CT reconstruction image has desired effect in navigation and positioning of pedicle screws after complex tibial plateau fractures, but has not yet been confirmed.

OBJECTIVE: To study the application effects of multislice spiral CT imaging in navigation and positioning of pedicle screws after complex tibial plateau fractures. 
METHODS: Eighty cases of complex tibial plateau fractures were selected from the Fifth Affiliated Hospital of Zhengzhou University from November 2014 to December 2015. All patients were treated with internal fixation with hollow nail and intramedullary nail. All patients were randomly divided into two groups, with 40 in each group. In the X-ray group, X-ray was used for screw navigation. In the spiral CT group, multislice spiral CT was used for screw navigation. The navigation effect of multislice spiral CT was assessed by comparing the repair effects between the two groups. 
RESULTS AND CONCLUSION: (1) In the spiral CT group, fracture site, the degree of comminution, bone fracture displacement, and impairment score were significantly higher than in the X-ray group (P < 0.05). (2) Surgery time, blood loss, and postoperative drainage were significantly less in the spiral CT group than in the X-ray group (P < 0.05). (3) Success rate of pedicle screws at the first time was significantly higher in the spiral CT group than in the X-ray group (P < 0.05). The success rate of pedicle screws at least twice was significantly less in the spiral CT group than in the X-ray group (P < 0.05). (4) Complication rate was significantly lower in the spiral CT group (8%) than in the control group (18%) (P < 0.05). (5) These findings suggested that spiral CT image reconstruction of complex tibial plateau fractures pedicle screw showed the desired effect, could determine the exact location and navigation of pedicle screws. The screws can be placed accurately, improve the cure rate, and promote early recovery of complex tibial plateau fracture.
