There is a novel method for creating a 2-d parameterized finite element model of the human femur with matching artificial hip joint based on X-ray image before the hip joint replacement surgery. It can help us to evaluate the selected appropriate hip joint prosthesis
The clinical management of skeletal trauma and disease relies on radiographic imaging to infer bone quality. However, bone strength does not necessarily correlate well with image intensity. There is a need for a safe and convenient way to measure bone strength in situ. This paper presents a new technique to directly measure bone strength in situ at a microlevel scale through a microelectromechanical...
The aim of the present study is to develop a comprehensive, geometric, nonlinear finite element model of the occipito-atlanto-axial (C0-C1-C2) complex. More accurate geometric and material properties profited from Visible Human Male dataset which was introduced for the first time in the finite element research of the cervical spine. The biomechanical response of the model was validated and corresponded...
A standardized and modularized finite element model of a normal human skull is established to simulate the unilateral defective pattern of the maxillary and the stress distribution of craniofacial skeleton with repair subject to the bite force. Based on the model, the stress evaluation of autologous bone grafted and zygomatic implant is to optimize the repairing method, and to rebuild the occlusal...
A large mandibular discontinuity defect is most often due to severe trauma, infection or resection for neoplasm. Reconstruction plates have been popularly applied to bridge mandibular defects without bone grafting. The esthetics and continuity of the mandible with segmental defects could be rehabilitated successfully. However, the function is difficult to reconstructed using this type of plate. Furthermore,...
In this study a three dimensional finite element model was established to analyze the interfacial stress distribution in the osseointegrated transfemoral prosthesis. The effects of implant length and screw pitch on the stress and strain distributions were analyzed in terms of bonded and contact bone-implant interfaces. The influences of the contact parameters, contact stiffness and friction coefficient,...
A three-dimensional accurate foot model including bones, cartilages, ligaments and tendons was developed from 3D reconstruction of CT images. The model was used to analyze stress-strain of the joint between the first metatarsal and the medial cuneiform and to study the relationship of the range of motion of the first ray and hallux valgus
