Auxetic materials for biomedical applications
The main aim of this project was to assess auxetic (negative Poisson's ratio) materials for potential in biomedical devices. Specifically, a detailed comparative indentation study has been undertaken
Development and Comfort Characterization of 2D-Woven Auxetic Fabric for Wearable and Medical Textile Applications
Knitted auxetic fabrics (AF) are in common practice but their stability and thickness are major problems in commercial applications. Therefore, a simple method of developing woven AF is proposed
Characterization of auxetic polyurethanes foam for biomedical implants
Abstract Aging, accidents and diseases are the leading causes of disability in today’s world. Therefore, implants and prostheses for hard and soft tissues are becoming increasingly common to restore
Auxetic materials and their potential applications in textiles
Auxetic materials are a kind of non-conventional materials having negative Poisson’s ratio. They laterally expand when stretched or laterally shrink when compressed. Compared to conventional

Biomechanics of Fusion and Stabilization
TLDR
Fusions are largely successful, Biomechanical data is complete except for some of the latest devices, and finite element analyses remain to be done or semirigid devices, interbody spacers, and artificial discs.
Effects of Rigidity of an Internal Fixation Device A Comprehensive Biomechanical Investigation
TLDR
It appears that the new concept of using viscoelastic washers can be to a patient's advantage to reduce the effects of a rigid device on the bone quality until the surgical fusion mass unites.
The relationship between disc degeneration and flexibility of the lumbar spine.
TLDR
The results suggest that kinematic properties of the lumbar spine are related to disc degeneration, particularly in grades III and IV, in which radial tears of the annulus fibrosus are found.
Response of Charité total disc replacement under physiologic loads: prosthesis component motion patterns.
TLDR
Charité TDR restored near normal quantity of flexion-extension range of motion under a constant physiologic preload; however, the quality of segmental motion differed from the intact case over the Flexion-Extension range.
Arthroplasty in the military: a preliminary experience with ProDisc-C and ProDisc-L.
TLDR
The preliminary experience with cervical and lumbar arthroplasty at the authors' institution indicates that arthro plasty is comparable with arthrodesis and may actually expedite return to active duty.
The Effect of Removing the Lateral Part of the Pars Interarticularis on Stress Distribution at the Neural Arch in Lumbar Foraminal Microdecompression at L3–L4 and L4–L5: Anatomic and Finite Element Investigations
TLDR
The removal of one fourth of the lateral aspect of the pars interarticularis has minimal influence on the stresses in the remaining L3 and L4 neural arches, and its removal leads to considerable stress increases.
Biomechanics of Back Pain

TLDR
A mechanistic account of back pain is offered which attempts to incorporate all of the most important recent advances in spinal research, and the concept of ‘functional pathology’ is introduced, according to which, back pain can arise because postural habits generate painful stress concentrations within innervated tissues, even though the stresses are not high enough to cause physical disruption.
Overview of disc arthroplasty—past, present and future
TLDR
The present systematic review attempts to give an overview of the current status of disc arthroplasty by identifying six randomised controlled trials that compared the final clinical outcomes of disc Archery and spinal fusion.
Biomechanics of two-level Charité artificial disc placement in comparison to fusion plus single-level disc placement combination.

TLDR
The biomechanical effects of the Charité artificial disc placed at two lower levels (2LChD model) with L5-S1 fusion (using a CG and a pedicle screw system) plus L4-L5 level ChD placement combination (CGChD models) were compared.
Degenerative Disc Disease
TLDR
This chapter focuses on the intervertebral discs, which constitute the principal connections between the vertebrae, and have two main functions: to serve as shock absorbers, and to allow movement of the spinal column.
