Peculiarities of tibial fragmental fixation for spiral fractures using the Ilizarov fixator (experimental study)

Rotation rigidity of fixation was studied experimentally using the Ilizarov fixator applied to bone fragments for tibial spiral fracture in the process of axial load action. A special test stand was made for this purpose. Acceptable axial load under transosseous fixation and the effect of changing a number of wires and threaded rods connecting the fixator supports on fixation rigidity were determined on the basis of measurements and mathematical calculations. Optimal configuration of the fixator applied to tibial fragments for spiral fracture was recommended.
