Abstract

OBJECTIVE

the aim of this study is try to show the best view for distal radius fractures so called die-punch fractures.

METHODS

There has been used a human cadaver radius bone from the Salvador Arena Tissue Bank. This bone was cleaned up after removing the soft tissues and osteotomies created displaced lunate fossa fractures of 0, 1, 2, 3 and 5 mm. We have fixed this fragment with adhesive tape. Then the joint deviation were significantly increased with step-offs of 1 mm. Radiographs were then taken into 5 different positions: postero-anterior view, lateral view, oblique views and tangencial view for each of the deviations. The resulting lunate fossa depression in each X-ray film was analyzed by the AutoCAD 2010® software.

RESULTS

The tangencial view was the best one to see the 1mm and 3mm bone degrees and the second one view to see the 2mm and 5 mm degrees. The pronated oblique view was the best to see the 2mm degrees and the oblique supinated view wasn't able to see the degrees between 1 and 2mm.

CONCLUSION

The tangencial view was the best one to see the 1mm and 3mm bone degrees and the second one view to see the 2mm and 5 mm degrees.

摘要

目的

本研究旨在探寻桡骨远端骨折（即所谓的冲模骨折）的最佳观察视角。

方法

使用了来自萨尔瓦多竞技场组织库的一具人类尸体的桡骨。去除软组织后对该骨进行清理，并制造出0、1、2、3和5毫米的移位月骨窝骨折。我们用胶带固定了该骨折块。然后随着台阶差为1毫米时关节偏移显著增加。接着在5种不同位置拍摄X线片：后前位、侧位、斜位以及每个偏移角度对应的切线位。通过AutoCAD 2010®软件分析每张X线片上所得的月骨窝凹陷情况。
