A 3D finite element model for charged hydrated soft tissue containing charged/uncharged solutes was developed based on the multi-phasic mechano-electrochemical mixture theory [1–2]. This model was applied to analyze the mechanical, chemical and electrical signals within the human intervertebral disc under mechanical loading. The effects of tissue composition and material property on the physical signals and the transport of fluid, ions and nutrients were investigated. This study is important for understanding disc biomechanics, disc nutrition and disc mechanobiology.

Fea Analysis

The paper presents a series of aspects regarding the design, manufacturing (through Rapid Prototyping) and FEA analysis of an intervertebral disk made from UHMWPE. In the first part are presented the most used model existing on the market. The CAD model and Finite Element Analysis (FEA) of the intervertebral disc (IVD) were made using the SolidWorks program. As a material, UHMWPE has been preferred due to good mechanical and biocompatibility characteristics.
