Summary
Finite element (FE) models are crucial for understanding spinal biomechanics and the increasing incidence of intervertebral disc degeneration (IVDD). Advanced FE models incorporating porous materials and penetration parameters offer more realistic simulations for diagnosis and treatment.
Area of Science:
- Biomechanics
- Biomedical Engineering
- Computational Modeling
Background:
- Intervertebral disc degeneration (IVDD) incidence is rising, significantly impacting health.
- Altered biomechanical factors are primary contributors to IVDD.
- Finite element (FE) models are increasingly utilized to analyze spinal biomechanics.
Purpose of the Study:
- To review and summarize existing literature on FE models of the intervertebral disc (IVD).
- To categorize different types and construction methodologies of IVD FE models.
- To analyze the applications of representative IVD FE models.
Main Methods:
- Comprehensive literature review of studies reporting IVD FE models.
- Systematic summarization of FE model types and construction techniques.
- Analysis of applications for selected, representative FE models.
Main Results:
- Nonlinear models, accounting for porous elastic material behavior, are most prevalent.
- Advanced FE models incorporating penetration parameters are increasingly employed.
- These advanced models enhance simulation of IVD biological behavior and biomechanical properties.
Conclusions:
- Personalized FE modeling is essential for accurate diagnosis and treatment of IVDD.
- Future models should integrate microstructure, cell behavior, and complex loading conditions.
- Developing more realistic FE models is key to advancing IVDD research and clinical application.

01:17Structural Joints: Cartilaginous Joints
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:27Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
01:23Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
