| Abstract: | The interfragmentary micromovement induced by mechanical vibration was measured in vitro in seven preserved adult cadaveric femurs by using accelerometers. Accuracy analysis of this method indicated that it can detect relative interfragmentary micromovement as small as 0.1mm or below under certain range of frequency.Also, the results have shown that the mechanical vibration can induce interfragmentary micromovement under intramedullary nailing, but it can not do so under plate fixation. |
