Possibilities of substantiated approach to femoral neck osteosynthesis using threaded fixators in view of mechanical and adaptation bone tissue properties

The aim of this work is to study the possibilities of individual surgical treatment of femoral neck fractures in subjects of young and middle age. The optical density of proximal femoral cancellous bone tissue was determined preoperatively using digital computer technologies. Computer modeling of the dynamics of mechanical properties, the parameters of proximal femoral cancellous bone structure and compression forces produced by threaded fixators was performed based on the data obtained. Individualization of the surgical treatment of femoral neck fractures consisted in applying rigid threaded fixators with the pre-calculated tightening moment. Fracture union was achieved in 18 subjects of young and middle age among 19 as a result of surgical treatment of femoral neck fractures using the technology mentioned. Thus, the technique has been developed providing an individual approach to osteosynthesis of femoral neck fractures by using threaded fixators and allowing to reduce significantly the number of unfavorable outcomes for femoral neck osteosynthesis in subjects of young and middle age.
