The use of power driven staples is an accepted method of fixation for small bones of the hand and wrist and of the foot and ankle. The staples must be applied to flat or nearly flat surfaces. A synthetic model was developed to evaluate the ability of the 3M power driven staple system to resist failure due to pulling out of the staples in cantilever bending, tension, and torsion. Three different staple configurations and two leg lengths were evaluated in each of the test modes. Results indicated statistically significant differences between one and two staple configurations and between longer and shorter leg lengths. There was clear superiority of the two staple configurations and of longer leg lengths.
使用动力驱动钉是手部和腕部小骨以及足部和踝部的一种公认的固定方法。钉子必须应用于平坦或近乎平坦的表面。开发了一种合成模型来评估3M动力驱动钉系统在悬臂弯曲、拉伸和扭转时抵抗钉子拔出导致失效的能力。在每种测试模式下评估了三种不同的钉配置和两种钉腿长度。结果表明，一种和两种钉配置之间以及较长和较短钉腿长度之间存在统计学上的显著差异。两种钉配置和较长钉腿长度具有明显优势。
