Structure-function relationships at the human spinal disc-vertebra interface. [PDF]

, 2018
Damage at the intervertebral disc-vertebra interface associates with back pain and disc herniation. However, the structural and biomechanical properties of the disc-vertebra interface remain underexplored.

The Effect of Degenerative Changes on the Stressed State of the Intervertebral Disc and Adjacent Tissues: A Finite Element Study

Applied Sciences
The work presents a finite element analysis of the mechanical interaction of adjacent tissues in degenerative conditions of the intervertebral disc. To address this, we developed a three-dimensional finite element model that included the L1–L2 vertebrae,

Friction in metal-on-metal total disc arthroplasty: effect of ball radius [PDF]

, 2012
Total Disc Arthroplasty (TDA) can be used to replace a degenerated intervertebral disc in the spine. There are different designs of prosthetic discs, but one of the most common is a ball-and-socket combination.

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Intradural Disc Herniation in the Lumbar Spine: A Case Report

Journal of Nepal Medical Association, 2020
Intradural disc herniation is a rare presentation of a common pathology, comprising around 0.28- 0.3% of all disc herniations. It occurs when disc material related to an intervertebral disc penetrates the spinal dura and lies in an intradural ...
