4.Precise mechanical analysis on the femoral three-dimensional finite element model constructed based on DICOM data
Chinese Journal of Tissue Engineering Research 2013;(30):5483-5489
BACKGROUND:The finite element model has been developed from two-dimensional model to three-dimensional model, from linear model to nonlinear model. As the advantage of this method in the analysis of mechanical characteristics of the irregular objects, the finite element model has been widely used in the research of orthopedic biomechanics, especial y in the research of hip joint. OBJECTIVE:To analyze the stress state of human femur with finite element analysis method and to investigate a method that can rapidly construct femoral finite element model and precisely analyze the biomechanics. METHODS:Normal male femur was used as specimen for CT scan to obtain cross-sectional images of femur in each slice. Three-dimensional reconstruction was performed with DICOM data and MIMICS software, then the femoral three-dimensional finite element model was established with the finite element analysis ABQUS 6.8 software, and the stress distribution of the model was analyzed under loading condition. RESULTS AND CONCLUSION:Based on DICOM data, three-dimensional finite element model of femur was constructed more quickly and precisely. The models were divided into 38 636 nodes and 201 422 units. The model included the parts of cortical and cancel ous bone. The biomechanical test results were accorded with the previous results, so the model could objectively reflect the real femur shape and biomechanical behavior with high precision. The Mimics software provided a simpler and effective method for the construction of femur model and improved the efficiency of modeling, and the three-dimensional finite element model based on DICOM data was accurate in shape and can be used for the normal research on biomechanical behavior of femur. The stress distribution analyzed with ABQUS 6.8 software is consistent with the clinical observation.

Journal of Practical Stomatology 2000;0(05):-
砄bjective: To study the rule of the degradation of HA artificial bone(HAB). Methods: The samples of HAB were immersed in PBS or distilled water (DW),the changes of the shape, weight, compressive strength of the samples and pH value of the immersion solutions were measred at the intervals of 2 or 4 weeks until 28 weeks. Results: At 4 weeks, HAB began to be degraded, 8 weeks later, the speed of the degradation slowed down. From 4 to 12 weeks, the compressive strength decreased rapidly. The pH value of the immersion solutions decreased from 2 to 12 weeks,but increased from 12 to 28 weeks when it was close to the neutral value. Conclusion: HA artificial bone can be degraded in PBS solution, and the degradation can cause noticeable changes of the compressive strength of the material and pH value of the immersion solution.
