Angular Stability of Intramedullary Elastic Osteosynthesis

Resumo

The article presents results of biomechanical bench tests of bone fragment fixation using the model of a transverse diaphyseal fracture in a long cortical bone in two mutually perpendicular planes for different modes of installation of flexible titanium rods by the flexible intramedullary nailing (FIN) method. The obtained results revealed a significant impact of the bending curvature of the rods, the plane of their placement, and the diameter and inclination of the perforation hole for rod introduction on the rigidity of fixation.
