Mechanical Properties of the Regenerate from Femoral Fracture Zone with the Use of Implants with Different Modulus of Elasticity

Abstract

An experimental study on the femoral bones of Chinchilla rabbits has been carried out. Femoral bones were taken from 4 experimental study groups: control group, in which surgery was not performed, and three research groups. All rabbits from the research groups underwent subtrochanteric fracture with subsequent osteosynthesis using metal rods. Animals in the second group were made osteosynthesis with nails made of stainless steel (316L), in the third — of titanium-vanadium (VT-6) and in the fourth — of zirconium-titanium alloy (Zr-Ti). Animals were removed from the experiment in 90 days after healing of femoral fracture. The mechanical characteristics of bone for extension and compression were assessed. It is established that the biomechanical indicators of bone extension are inferior to the similar performance in compression, bones in the presence of fixation devices have the higher strength in the area of healed fracture than the bones of the control group animals. When studying the function of bone regenerate for extension and compression, the best strength results were determined in bone samples with the presence of fixation device from β-Zr-Ti alloy. This study proves the feasibility of the development and introduction into clinical practice of orthopedic trauma surgeons of implants on the basis of low-modulus β-Zr-Ti alloy that will improve the results of treatment for long bone fractures and reduce the postoperative complications rate.
