TIBIAL BONE NONUNION PLASTIC WITH THE USE OF MONOLOCAL OSTEOSYNTHESIS BY RING FIXATORS

Abstract. Actuality. Monolocal extrafocal osteosynthesis by ring fixators (RF) of tibial nonunion is not a generally accepted method, there are no systematic guidelines for its implementation. These issues need to be further studied. Task. Formulate situational predominant properties of RF; features of application in different condi-tions. To offer a method of nonunion plastics and features of monolocal osteosynthesis of RF and to study its efficiency. Materials and methods. The data of treatment of 16 patients with aseptic nonunion of tibia, who required complex comprehensive specialized medical care with a possible positive result (scores from 51 to 75 according to the evaluation system Non-Union Scoring System - NUSS). Implementation of monolocal extrafocal osteosynthesis of RF nonunion of shin bones after fractures was performed by us taking into account the features that distinguished it from that by fractures. The principal requirement of surgical intervention was the need to treat the center of nonunion, local stimulation of repara-tive processes. The technical features of all components of the intervention in the future were of great im-portance. The so-called blood-saving tactics were used, which were carried out using squeezing and hemostatic tourniquets, tranexamic acid. The results obtained. The results of treatment of victims with nonunion of the tibia with the use of RF in monolocal mode were as follows. Taking in consideration the severity of the lesion, we consider this result to be good. Given the insufficient number of observations, it is necessary to continue the use of the proposed method of treatment and to investigate its effectiveness. Conclusions. 1. The use of monolocal RF in patients with nonunion of tibia after fractures has the advantage of use in cases with episodes of septic inflammation in the past, extensive scarring of soft tissues, short distal fragment and osteoporosis. 2. The peculiarities of monolocal osteosynthesis of RF were the use of thick Ilizarov needles Ø 2.0 mm with their conduction at an angle of two planes. The obtained results of treatment of victims with nonunion of the tibia with the use of RF in the monolocal mode should be considered encouraging.
