Mathematical modeling of the osteosynthesis of the lower leg bones using a titanium mesh for their congenital pseudoarthrosis in the lower third

Background. Congenital pseudarthrosis of the lower leg bones belongs to group orphan diseases and manifests itself in non-union (pseudarthrosis) bones, which leads formation deformity shortening limb, and, as a result, is accompanied by persistent violation limb’s supportability. To date, question choosing surgical technique optimal fixation treatment congenital remains unresolved. The purpose was investigate stress-strain state shin model with its third during their osteosynthesis using titanium mesh. Materials methods. Osteosynthesis simulated an intramedullary nail, wires, block bone grafts on both imposition mesh over under influence two types compression torsion loads. Results. Studies have shown that additional graft allows reducing stress level at almost all control points pseudarthrosis, torsion. As most positive changes, we can note decrease values tibia around nonunion line. This be explained fact reinforced takes great load. same contributes increase border tibia. negative factors include along line fibula. also modulus elasticity block, further loads Conclusions. use for has effect model, confirmed changes are observed
