Methods A wet hip joint's sample from corpse was scaned by CT and all images of every cross-section hip joint's layer was obtained, and an hip joint's model was contructed with Unigraphics NX 2.0 and Solid Works 2006 SP 0.0 software. The models were assembled when simulated total hip arthroplasty after total hip joint prosthetic and ischiofemoral ligament model had been constructured. Analysis was done on von Mises stress distribution and amount of total hip component when simulated seated leg-crossing manuver. The bone and metal components were meshed as rigid bodies, composed of three-dimensional, all-quadrilateral rigid body elements, and hip joint capsule ligament was fully three-dimensional, hexahedral continuum elements representations. Results The current form of this ischiofemoral ligament's reconstruction finite element model provided for multi-body contact, large displacement interfacial sliding, large deformation capsule ligament representation, and clearly reflected the real ischiofemoral ligansent's anatomy and biomechanical behavior. The maximum on Mises stresses at the joint interface was more than that fur an otherwise identical hardware-only construct.

Directly reading the 210-layer of 0.65-mm-thick consecutive CT Dicom format images of human body thoracolumbar making use of 0.625-mm isotropous resolution thin layer scanning technique into the Mimics. Defining bone organization threshold, withdrawing each outline, partitioning each edge of layer picture, edited selectively and repaired by hole processing. After a redundancy data was cleaned, the thoracolumbar 3-D finite element geometry model was acquired. Then area mesh could be kept as the document Ansys named .lis as the suffix and be introduced into Ansys software directly to mesh body, and then transferred the body mesh to mimics to assignment son the basis of CT values, once again import Ansys to establish 3-D finite element model.

Methods Four lumbosacral spinal specimens of human were used to manufacture the intact segmental specimen, then the specimen models were worked out by cutting the isthmic of intact specimens with wire-saw, and then one pure bone-towel or one anterior fusing cage was inserted separately into the model's interbody space to stable the model. Finally, all of the specimens' stiffness of the upper four conditions was measured.
