Construction of a three-dimensional finite element hip model based on Chinese visible human dataset for biomechanics
Objective To construct a three-dimensional (3-D) finite element hip model including acetabular bone
cartilage
labrum and bone
cartilage of femoral head based on Chinese visible human dataset for biomechanics. Methods The images of hip dataset in Chinese visible human (CVH) were obtained for construction of hip biomechanical model. A hip model including acetabular bone
cartilage
labrum and bone
cartilage of femoral head was constructed with AutoCAD and Solidworks software by using these images. The hip model was imported into ABAQUS analysis system for meshing of the hip joint contact surface
and then loading test (400 N) was performed at 5 hip flexion and 20 external rotation. The contact pressure distribution on the cartilage and labrum was observed. Results The constructed 3-D hip model reflected the real hip anatomy. The constructed 3-D finite element hip model reflected biomechanical behavior similar to the results from previous researches. Conclusion The hip dataset of CVH can be used for accurate 3-D reconstruction. The construction of the 3-D finite element hip model can avoid some disadvantages by other construction methods
such as imprecision of cartilage construction and absence of labrum
and hence can provide basic data which are critical for accurately modeling normal loads as well as for observation of abnormal conditions of the hip.
