Use of Composite Materials for External Fixators

Popis výsledku v původním jazyce

This article focuses on ring (Ilizar) external fixators in traumatology and orthopedics. External fixator is a construction system that is used in the treatment of complicated or infected fractures of long bones, shortening and extension of bones, correction of angular deformations and similar applications. The engineering-biomechanical aspect is a critical perspective, taking into account the recommendations of medical specialists, the design of materials for the fixator components, the development of surface treatment methods, and the optimization of proposed concepts and the implementation of experimental verification. The frame of the circular fixator consists of outer rings and K-wires. This type of variable-position fixator is frequently used in the management of tibial fractures. It is located outside the human body for several weeks to months. The external fixation method allows continuous treatment of the wound site and the patient is mobile after a few days. The surgical steel external fixators are found heavy for the patients. By replacing some of the metal components of the fixator composite material, such as e.g. a ring frame can be achieved overall lightening of the entire structure. In addition, carbon or hybrid carbon / aramide reinforcement composites have excellent mechanical properties such as high stiffness, high strength and low density. A suitable matrix selection is to obtain a composite material which has high chemical resistance and resistance to thermal deformation. These have excellent properties and others, such as high impact strength, make the composite a material suitable for orthopedic applications and surgical procedures. The aim of this paper is to present the practical experience and the results obtained during the cooperation of medical specialists and engineers (overview of used materials, design, laboratory experiments, modeling of finite elements) and to design a metal external fixator using composite materials in combination with a polymeric matrix.
