Importance and aims of the research
Biomechanics science is interested in studying the dynamic function and the
movement of vital tissues depending on their mechanical properties.
The main objective of this research is to design a digital model of
the human femur
using the engineering software specialized in medical image processing and engineering
design in order to simulate the mechanical behavior. This would provide important medical
information to orthopedic surgeons concerning the paths and the causes of bone fractures
and deformities, and open a new perspectives in prosthetics efficiency enhancement.
Materials and methods
A three dimensional digital model of the femur was produced using the software
DeVIDE v 9.8 for medical image processing. A surface triangular mesh was constructed
and the mechanical response of the model has been simulated using Ansys 14.5.
Results and discussions
We have shown the steps necessary to design a computerized model of femur bone
on the basis of three-dimensional X-ray images. The results showed the distribution of
stresses and displacements of human femur at normal load conditions.
Conclusion and recommendations
It is recommended to adopt the specialized engineering software for the threedimensional
simulation which can be used in different medical applications.
Bone healing is a complicated biological mechanism that is affected by many hormonal, nutritional, and hemal factors. The term Biomechanical theory of bone healing is a concept that is created by us and is used for the first time to identify and stud
y the influence of mechanical rules on the bone tissue so we can study and imitate its mechanical response depending on the rules of balance and movement. We ensure that bone healing is just adaptation to auto bone forming mechanism in the surrounding mechanical site. The term is more comprehensive and accurate than the bio-compression term which was used before; and all of those are confirming the criteria to evaluate the efficacy of fixators used in orthopedic surgery.
