The objective of this study is to evaluate the difference between the amount of bone visible with the superimposition of a radiolucent hybrid external fixator and a graphically simulated metallic frame. Eighteen frames were applied to eighteen bone specimens. The fracture area (FA), the radiolucent area (RLA) and the radiopaque area (ROA) inside the FA were calculated for each construct on both postoperative views. The ratio between the RLA and FA and between the ROA and FA was used to evaluate the amount of bone visible in the FA with a radiolucent and a radiopaque fixator, respectively. Finally, the areas of RLA and ROA were compared using the Wilcoxon test and Friedman test to evaluate the effect of the radiolucent material on the amount of bone visible. Differences were considered significant if p < 0.5. In every specimen p was <0.5. The amount of bone visible was significantly higher with the radiolucent frame compared to the radiopaque frame. Based on the results of this study, the use of radiolucent materials can be a valuable option for external fixation, in order to decrease the radiographic interference of the frame, allowing better assessment of fracture reduction and bone healing on postoperative radiographs.
本研究的目的是评估使用射线可透过的混合外固定器与图形模拟金属框架叠加时可见骨量的差异。将18个框架应用于18个骨标本。在术后的两个视图上，针对每个构建物计算骨折区域（FA）、射线可透过区域（RLA）以及FA内的射线不透光区域（ROA）。RLA与FA的比值以及ROA与FA的比值分别用于评估使用射线可透过和射线不透光固定器时FA中可见的骨量。最后，使用Wilcoxon检验和Friedman检验比较RLA和ROA的面积，以评估射线可透过材料对可见骨量的影响。如果p < 0.5，则认为差异具有显著性。在每个标本中，p均<0.5。与射线不透光框架相比，使用射线可透过框架时可见的骨量显著更高。基于本研究的结果，使用射线可透过材料可能是外固定的一个有价值的选择，以减少框架的放射学干扰，从而在术后X线片上更好地评估骨折复位和骨愈合情况。
