Abstract
The characteristics of stiffness are studied and the fixation means allowable load at fractures of the distal epimetazh of the tibia is calculated. The processes of a fracture points mutual displacements development under the influence of long-term cyclic loads are studied. Metal osteosynthesis was performed using various types of medial and lateral plates with angular stability and blocked plates for fixing fractures in the distal epimetazh of the tibia. The tests are conducted under the influence of actual physiological loads of compression, bending and torsion, including cyclic loading modes. Keywords: osteosynthesis; tibial, occipital plates, stiffness of fracture fixation, fracture fixation strength, fracture fixation stability
Highlights
The tibia fractures with displacement of fragments belong to complex fractures that lead to longterm disability or even total disability
The tibia is the main supporting bone, which integrity basically depends on the function of the shin
There is no single point of view regarding the shape and size of the plates for fixing complex fractures of the tibia, in order to determine the optimal configuration of the plates, it is necessary to compare the rigidity of fixing the fragments using various fixatives
Summary
The tibia fractures with displacement of fragments belong to complex fractures that lead to longterm disability or even total disability. The fixation of fractures by standard and new plates, in addition to clinical indices, must have certain mechanical characteristics, in particular, sufficient rigidity and stability in long-term treatment, which can be accompanied by cyclic loads. There is no single point of view regarding the shape and size of the plates for fixing complex fractures of the tibia, in order to determine the optimal configuration of the plates, it is necessary to compare the rigidity of fixing the fragments using various fixatives. That is why it is necessary to develop a technique for conducting a full-scale experiment, to determine and compare the mechanical characteristics of the "bone-fracturefixing plate" system under the influence of external loads. Direct transverse fractures at the level of the distal bone epimetaphysis were simulated on all tibia speciments [8]. Fractures were modeled by transverse osteotomy by an oscillatory saw and fixed by metallosteosynthesis using various plate variants (Figure 1, Table 1)
