摘要

在胫骨愈合的类比中检查了多个频率模式。用带仪器的锤子敲击木榫，并在木棒的另一端监测加速度计，从而检测木榫。三种频率模式确定了完整杆，以及部分横向切割杆(1/4,1/2,3/4直径深度)。用胶水或泡沫修复完全切割的骨棒，模拟完全和不完全的骨愈合。使用多种频率模式被确定为比单一的第一种模式更好的预测切骨。修复后的棒材也显示出类似的结果。这项工作证明了频率检查的有效性，而不是简单的第一模式确定分析骨愈合。讨论了影响和未来的工作。

Multiple modal frequency analysis for monitoring of bone healing

Multiple frequency modes were examined in an analogy of tibial bone healing. Wooden dowels were examined by striking with an instrumented hammer and monitoring an accelerometer at the other end of the rod. Three frequency modes were determined for intact rods, along with rods with partial transverse cuts (1/4, 1/2, 3/4 diameter depths). Fully cut rods were repaired with glue or foam to simulate complete and incomplete bone healing. The use of multiple frequency modes was determined to be a better predictor of cut bone than the first mode alone. Repaired rods displayed similar results. This work demonstrates the validity of frequency examination beyond simple first mode determination for the analysis of bone healing. Implications and future work are discussed.<>
