Tibial shaft fractures: locked nail versus extending one

The mechanical properties of bone-implant system under the conditions of osteosynthesis different variants for tibial shaft fractures have been studied. Any variant of stable-and-functional osteosynthesis has been revealed to provide the greater stability of synthesized segment to increasing axial load than that of intact sample. The systems of intramedullary fixation have demonstrated the greatest stability to axial compression, however, the systems of extrafocal fixation have shown the longest stabilty to loading. The systems, fixed with LC-DCP plates, were the least strong among those examined, nevertheless, their stability was 22% more on the average, than that of the intact samples of control group.
