The wave signal from percussion of a bone (i.e. percussion-note) has been used to evaluate the extent of bony consolidation after fracture. Forty-one cases with a fresh tibial fracture and eight cases of delayed union of the tibia were investigated. The medial malleolus of the tibia was struck with a tapper and the vibration signal was picked up at the medial region of the tibial tuberosity. The changes in the signal waveform of the percussion-note with time were investigated. As healing proceeds, the signal waveform of the fractured bone approaches that of intact bone. In cases of delayed union, the character of the wave does not improve sufficiently with time. The authors are convinced that this is a promising new method for the early diagnosis of delayed union.
来自骨骼叩击的波动信号（即叩诊音）已被用于评估骨折后骨愈合的程度。对41例新鲜胫骨骨折病例和8例胫骨延迟愈合病例进行了研究。用敲击器敲击胫骨内踝，并在胫骨结节内侧区域采集振动信号。研究了叩诊音信号波形随时间的变化。随着愈合过程的进行，骨折骨的信号波形接近完整骨的信号波形。在延迟愈合的病例中，波形特征不会随时间充分改善。作者确信这是一种用于早期诊断延迟愈合的有前景的新方法。
