The inter-lamellar connectivity of the annulus fibrosus in the intervertebral disc has been shown to affect the prediction of the overall disc behaviour in computational models. Using a combined experimental and computational approach, the inter-lamellar mechanical behaviour of the disc annulus was investigated under conditions of radial loading. Twenty-seven specimens of anterior annulus fibro...

background & aim: low back pain is the most debilitating condition, and can lead to decreased physical function, compromised quality of life, and psychological distress. several studies have been conducted to recognize the risk factors of low back pain, but despite of strong relationship between obesity and low back pain, the underlying mechanisms are unclear. the aim of this study was to evalu...

conclusions in this study, we found that in spite of previous beliefs, discopathies were not common etiologies of lbp. thus, even in patients with proven ldh by imaging studies, the physician should perform a thorough evaluation for other causes of lbp to avoid unnecessary lumbar surgeries. results in our study, among 1250 patients with proven ldh by mri, 500 patients (40%) had chronic lbp and ...

The oceans' phytoplankton that underpin the marine food chain appear to be changing in abundance due to global climate change. Here, we compare the first four years of data from a citizen science ocean transparency study, conducted by seafarers using home-made Secchi Disks and a free Smartphone application called Secchi, with contemporaneous satellite ocean colour measurements. Our results show...

We present two cases of disc herniation associated with juvenile intervertebral disc calcification, a rare, self-limiting process which typically resolves with conservative treatment. Recognition of this entity prevents unnecessary diagnostic workup and possible surgical intervention. A review of the literature for this rare entity is discussed.

BACKGROUND Canine intervertebral disc degeneration can lead to intervertebral disc disease. Mild degenerative changes in the structure of the canine intervertebral disc can be identified in magnetic resonance images, whereas these changes are not visible in computed tomographic images. Therefore, one aim of this study was to detect whether colour-coded computed tomography enhances the visibilit...

Background & Aim: Low back pain is broadly documented as one of the most widespread pathologies in the advanced domain. Although the reasons of low back pain are uncountable, it has been meaningfully related to intervertebral disc degeneration. Present therapies for Intervertebral Disc (IVD) degeneration such as physical therapy and spinal fusion reduce symptoms' severity, but do not treat the ...

Nucleus replacement technologies are a minimally invasive alternative to spinal fusion and total disc replacement that have the potential to reduce pain and restore motion for patients with degenerative disc disease. Finite element modeling can be used to determine the biomechanics associated with nucleus replacement technologies. The current study focuses on a new nucleus replacement device de...
