[Diagnosis of fractures by sound].
For the purpose of objective evaluation of the sound diagnosis the authors have generalized an experience of application of four methods of the acoustic diagnosis of bone fractures. There have been compared the efficiency of the auscultatory percussion method, the method of its objectivization by means of measuring devices, the sound diagnosis method, following the pattern of auscultatory percussion and self-sustained oscillation measuring method. There have been noted the high efficiency and up to 98% coincidences with clinico-roentgenologic data in case of application of the sound diagnosis method with the self-sustained oscillation systems.
