Numerical Analysis of Standard and Modified Osteosynthesis in Long Bone Fractures Treatment

The fundamental problem in osteoporotic fracture treatment is significant decrease in bone mass and bone tissue density resluting in decreased firmness and elasticity of osteoporotic bone. Application of standrad implants and standard surgical tehniques in osteoporotic bone fracture treatment makes it almost impossibile to achieve stable osteosynthesis sufficinet for early mobility, verticalization and load. Taking into account the form and the size of the contact surface as well as distribution of forces between the osteosynthetic materials and the bone tissue numerical analysis showed advantages of modified osteosynthesis with bone cement filling in the screw bed. The applied numerical model consisted of three sub-models: 3D model from solid elements, 3D cross section of the contact between the plate and the bone and the part of 3D cross section of the screw head and body. We have reached the conclusion that modified osteosynthesis with bone cement resulted in weaker strain in the part of the plate above the fracture fissure, more even strain on the screws, plate and bone, more even strain distribution along all the screws' bodies, significantly greater strain in the part of the screw head opposite to the fracture fissure, firm connection of the screw head and neck and the plate hole with the whole plate and more even bone strain around the screw.
