摘要
对超声波的促进骨折愈合作用进行了动物实验和临床初步观察。Ｘ线检查显示实验侧骨缺损处新生骨痂各阶段普遍比对照侧出现早且多；组织学观察显示实验侧骨折修复较对照例明显加快；生物力学测试显示实验侧最大扭矩、最大刚度、最大能量吸收平均高于对照例４２．３～４８．９％，转角８°时各指标平均高于对照例５５．３～６６．２％。临床观察结果显示该法能较快消除肿胀、疼痛，加速骨痂形成，缩短临床愈合过程。上述结果表明低频脉冲超声波具有穿透力强、不产生热效应、治疗时间短、使用方便、无不良反应，及适用于采用不同固定方法的甚或有创面、有感染的各种各部位的新鲜或陈旧性骨折等优点。应用广泛，疗效可靠，为治疗骨折提供了一种新方法，开辟了一个新途径。
Animal experiment and primary clinical Olbservations on the stimulativeeffects of low-frepuency pulse ultrasonic waves(LFUW)on fracture healing are reported in the paper. Radiological observations showed that the neoformed callus at the experimental side appeared more and earlier than that at the control side ; histological observations showed that the fracture repair at the experimental side was much more rapid than that at the control ibiomechanical measurements showed that the means of the greatest torque, rigidity and energy absorption at the experimental side were higher than those at the control by 42. 3%48. 9%. The results of clinical observations showed that this method could rapidly eliminate swellings and pains, speed up callus formation and shorten clinical healing period. All of the above indicates that LFUW has many advantages , such as strong penetrativity, no thermal or adverse effects produced ,short therapeutic time, easy and simple operation , wide indications . including fresh or old fracture , wound or infection , cases using different fixating methods,and so on. It has reliable therapeutic results and offers a new approach to fracture treatment.
