Marchenkova N. Small-invasive osteosynthesis fractures of the ankle

An object - is patients which had the ankle fractures and operated; purpose – to improve the results of treatment and decrease the level of disability of patients with ankle fractures on the basis of grounds and improvement of small-invasive ostheosynthesis with the use of spokes and compressing apparatuses; methods - are clinical, roentgenologic, biomechanics, instrumental, statistical, the studies of bone mineral density; novelty – for the first time: mathematical design, of reasons of the secondary displacements of fragments at the use of the Yedynak apparatuses, is grounded on the possibility of small-invasive osteosynthesis with the use of wires in theory and experimentally-biomechanics, the Yedynak apparatuses and developed device at different types of ankle fractures, have proved that usage of the proposed system of a small-invasive osteosynthesis reduces the blood circulation restoration period in the fractured area up to 11.43 %, allowed to receive positive results of treatment in patients when bone tissue mineralization is ranging from normal to the first or second stage of osteopenia; results - has been confirmed a high efficiency of small-invasive methods during treatment of open fractures of the ankle, simple fractures followed with skin injury and concomitant pathology of the lower extremities vessels, during treatment of type А1-3, В1-2 and С1 of ankle fractures and as well during inter-shin syndesmosis laceration, Usage of small-invasive osteosynthesis methods for ankle fractures treatment twice decreased the amount of cases of the second displacements of wreckages, reduced the time of treatment in 1.22 times, allowed to receive positive results in 98.66 % of patients and as well to decrease invalidity in 1.47 times.
