Introduction: In order to make a hole on the bone cortex, especially, in the tumors of body in order to do biopsy and curettage creating a hole circularly is routinely recommended. In evaluating resources and references for obtaining documentation based on prioritizing circular holes in bending load and pressure, no positive evidence was observed. For this purpose, two methods of software analysis and force test experiments were used.
Material and Methods: Different forms of holes with an equal amount of area were created on 40 femur rabbit bones under the pressure and bending forces of a hydraulic system in laboratory. The required bending force was calculated by the computer. At the same time, the software analysis of the simulation experiment under the ANSYS system were conducted by the University of Biomechanical Research Team.
Results: The results of the software analysis under the ANSYS system revealed that in pressureand bending load, there was no significant difference in the amount of strength remained in the bone in the presence of a circular hole and other shapes of holes, such as Trapezoid.
Conclusion: The amount of decreased strength in a circular hole did not have a significant difference with regard to none-circular shapes such as trapezoidal. It can be said that other factors such as the type of loading were more effective in decreasing the strength.
