Comparative evaluation of methods for osteosynthesis of diaphyseal radial fractures by the method of mathematical modeling

RELEVANCE. The surgical treatment of patients with diaphyseal forearm fractures has a variety methods and requires precision technique. need for postoperative immobilization after osteosynthesis remains controversial issue, since failure the formation pseudoarthrosis are sometimes observed. In addition, very little information about role interosseous membrane in rotational function during is available literature. OBJECTIVE was to determine forces occurring movements that lead above complications. METHODS AND MATERIALS. clinical part included results 330 forearm; it consisted main group (170 - interlocking osteosynthesis) comparison (138 plate osteosynthesis). third 22 complications forearm. We performed comparative assessment radial bone by mathematical modelling rotation nonunion, instability fractures. RESULTS. group, healing achieved all patients), 128 (92.8 %), consolidation fracture who underwent reconstruction. A revealed osteosynthesis, zones high stress concentration were located around opening area nearest holes from both sides. radius, stresses evenly distributed nail. Pronation-supination an amplitude (±90)°, according experimental results, should destruction cortical fairly soon implantation, while nail made ultra-fine Ti-6Al-7Nb alloy will maintain its integrity. CONCLUSION. Based on these findings, external advisable avoid such as or fracture.
