Dergachov V. The treatment of epimetaphyseal fructures of distal humerus with external fixation

Object of research it is the phenomenon of mechanical interaction between fragments of humerus and environmental soft tissues and process of their moving with traction of injured segment; "behaviour" of a design fragments it is the external device on stages fractures of distal humerus treatment; processes of healing a fractures, with osteosynthesis of external fixation and recovery of function elbow. Methods of research - clinical, radiological (X-ray examination), biomechanical, mathematical and computer modelling of external fixation and fractures, statistical. New knowledges about mechanical interrelation of fragments distal humerus with a capsule elbow were received, they have allowed to predict results of fragments closed reduction with traction and to allocate variants of fractures, which can be cured by a technique of uninvasive interventions using external device. This knowledge change widely widespread representations about necessity of fragments comparison in cases of splintered fractures ofthis localization, only by wide arthrotomy. They form a new direction in treatment of these injuries. New knowledge about properties of connection "a bone - a screw" at a level of epiphysis and shaft humerus were received, and also new knowledge of possible movings fragments were received using offered designs. It was established, that the offered design " fragments - external fixation" keeps the steady condition with functional loadings of injured extremities. External fixation for fixing bone fragments for fractures of distal humerus were designed. Ways of fractures' treatment of distal humerus were developed by the offered device on which is received patents of Ukraine № 31496. The offered techniques can be use in the specialized departments: city and regional hospitals. Techniques are introduced in traumatologic branches: the Kharkov regional clinical traumatologic hospital; city clinical hospital № 2; clinical versatile hospital № 17 "public enterprise" factory named by Malyshev; city clinical versatile hospital № 25; regional hospital of Pervomayskiy and Chuguev of Kharkov region. Traumatology and orthopaedics.
