A simple and reliable method is described for testing the stability of external fixators under stresses similar to those found in clinical practice. Unilateral uniplanar, unilateral biplanar, and bilateral uniplanar frames were used. It seemed important to measure deformations under bending stresses in different planes, because we have found a variable rigidity in some of the frames in the different planes. Our results show that a unilateral biplanar frame without transfixation pins can be set up with an overall rigidity as good as that of a bilateral frame. Using this on the leg, one can avoid putting pins through the anterolateral compartment.
本文描述了一种简单可靠的方法，用于在类似于临床实践中所发现的应力条件下测试外固定器的稳定性。使用了单侧单平面、单侧双平面和双侧单平面框架。在不同平面的弯曲应力下测量变形似乎很重要，因为我们发现在不同平面中一些框架的刚度存在差异。我们的结果表明，一种没有贯穿固定针的单侧双平面框架可以构建出与双侧框架相当的整体刚度。将其应用于腿部时，可以避免将针穿过前外侧肌间隔。
