Abstract


Purpose. To analyze the functional-and-ergonomic characteristics of external fixators (EF) of different types, as well as to develop the system of their evaluation and predict the effectiveness of their use in clinical practice.
Materials and Methods. The study of the functional-and-ergonomic characteristics of external fixators (EF) performed in terms of mechanics basic principles being the basis of functioning the mechanical systems for targeted and graduated movement of the bodies fixed in them.
Results. The direct dependence of the results of treatment of long bone fractures on EF functional-and-ergonomic characteristics demonstrated in clinical material. The system of their evaluation proposed which predicted the effectiveness of EF use in clinical practice.
Conclusion. Systematic work to improve the EF in order to increase their potential should be based on the principles of mechanics and ergonomics. The main ergonomic characteristic of the EF is the number of independent movements carried out by them. There is a close connection between EF ergonomic characteristics, physician productivity, periods of treatment, and the quality of the results achieved.
