METHOD FOR REGISTERING BIOMECHANICAL PROPERTIES OF LONG TUBULAR BONES Russian patent published in 2006 - IPC A61B8/00 

FIELD: medicine, traumatology, orthopedics.

SUBSTANCE: the present innovation deals with predicting lesions and diseases of long tubular bones. The method enables to study biomechanical properties of bones based upon the analysis of mechanic responses after standard stroke-type diagnostic impact. One should perform a dosed stroke in a certain point of a bone followed by receiving, enhancement and analysis of mechanical responses in other parts of this bone due to wide-strip seismographs followed by the analysis of the parameters obtained by the time of signals appearance, maximal amplitude, duration, frequency and degree of attenuating of mechanical impulse. Moreover, diagnostic sensors should be located along both sides against supposed pathological process, that is both from the opposite side and at the side of stroke impact. Then comes comparative analysis of the signal obtained against ideal exponent to detect the degree of soft tissues impact. The degree of fragments contact in case of fractures should be calculated by the decrease of signal's maximal amplitude obtained from a distant seismograph and, also, by the time and maximal amplitude of reflected signal from the nearest one. Mineral density and homogeneity of bony tissue should be detected according to the alteration in frequency and degree of attenuating of mechanical responses from different seismographs.

EFFECT: higher accuracy of diagnostics.
