METHOD OF CONTROLLING RATE OF DISTRACTION IN FOCUS OF OSTEOGENESIS Russian patent published in 2012 - IPC A61B5/01 A61B5/53 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and can be used for controlling rate of distraction in focus of osteogenesis. For this purpose rheographic analysis of regional blood flow of affected shin with determination of rhepgraphic index (RI) and maximal rate of rapid blood filling (MRRBF) from the beginning and to the end of distraction is performed. After that thermal diagnostics in osteogenesis focus is carried out by means of thermovision camera and temperature magnitude (TM) is determined. Before the beginning of distraction and 1 time per week temperature magnitude (TM) is determined. Before the beginning of distraction and 1 time per week until its end general index (GI) of bone tissue state in osteogenesis focus is determined by formula: GI+RIxMRRBFxTM. If GI value is lower than 1.0, rate of distraction is reduced to 0.5 mm a day. If GI value is from 1.0 to 2.0 rate of distraction is reduced to 0.75 mm a day. If GI value is higher than 2, distraction is performed at rate 1.0 mm a day.

EFFECT: method makes it possible to increase accuracy of distraction rate determination before operation and control it in the course of treatment due to simultaneous assessment of totality of analysed parameters of affected lower extremity, ensure, as a result, obtaining adequate bone tissue in zone of osteogenesis in earlier term with social rehabilitation of the patient.
