Implant for Fixing Trochanteric Fractures of the Femur

Abstract

The technique of three-dimensional geometric modeling of the proximal section of the human femur is described based on computed tomography data. The results of the finite-element modeling of the system “femur — fixator” are presented. The shape and size of the fixing implants of the proximal femur are determined. An implant-fixator design has been developed that provides compression of the fragments and prevents the penetration of the cervical screw into the cavity of the hip joint. The experimental samples of titanium fixators of the distal tibia were tested for static bending and cyclic durability.
