Numerical evaluation of scaffolds as a method to restore continuity of a long bone
Purpose
In case of necessity of removing a bone fragment, the process of restoring bone continuity relies on the use of bone grafts or bone plates as osteosynthesis methods. These approaches are characterised by several disadvantages, such as significant changes in load transfer method through the bone. Recently, scaffolds emerged as potentially more efficient method in restoring bone continuity. In this paper, an attempt was made to validate the correctness of this statement.
Materials and methods
Three lengths of bone defects were selected for the analysis: 35, 45 and 55 mm, located in the lower, middle and upper section of femur diaphysis. The following methods of restoring bone continuity were evaluated: 1 plate, 2 parallel plates, 1 plate and scaffold, 2 parallel plates and scaffold. Simulations of the forces generated during human gait cycle were performed. The evaluated parameters obtained were: maximal and average stresses, strain energy density as well as percentage changes in values of these parameters in relation to the values obtained for intact bone in its selected zones.
Results
Studies have shown that the best method of restoring bone continuity is to use a single plate with a scaffold. The stress distribution obtained by this method had the highest similarities to the one obtained for intact bone model in terms of load transfer as well as maximal stresses values obtained.
Conclusions
The study validated the statement that the use of a scaffold to restore bone continuity is potentially more efficient method than conventional approaches.
期刊介绍:
Computational Science is a rapidly growing multi- and interdisciplinary field that uses advanced computing and data analysis to understand and solve complex problems. It has reached a level of predictive capability that now firmly complements the traditional pillars of experimentation and theory.
The recent advances in experimental techniques such as detectors, on-line sensor networks and high-resolution imaging techniques, have opened up new windows into physical and biological processes at many levels of detail. The resulting data explosion allows for detailed data driven modeling and simulation.
This new discipline in science combines computational thinking, modern computational methods, devices and collateral technologies to address problems far beyond the scope of traditional numerical methods.
Computational science typically unifies three distinct elements:
• Modeling, Algorithms and Simulations (e.g. numerical and non-numerical, discrete and continuous);
• Software developed to solve science (e.g., biological, physical, and social), engineering, medicine, and humanities problems;
• Computer and information science that develops and optimizes the advanced system hardware, software, networking, and data management components (e.g. problem solving environments).
