Annular Fissure | MRI findings with a Chronic Low Back Pain Patient

History 43 yr old female, lower back pain with proximal right leg pain, for two years. Onset was due to repetitive torsional lifting over one 8 hour shift when a conveyor belt became dysfunctional. Pain onset was progressive. The patient…

The role of structure and function changes of the sensory nervous system in intervertebral disc-related low back pain

Goal of the study?   In this review [1. The role of structure and function changes of the sensory nervous system in intervertebral disc-related low back pain], the authors have two goals:   To determine how changes that…

Annulus Fibrosus Susceptible to Damage During Spinal Growth-Plate Fractures

Researchers examined the effects of endplate fractures  [1. Pressure-induced end-plate fracture in the porcine spine: Is the annulus fibrosus susceptible to damage? ] on the mechanical properties of the annulus fibrosis (AF) in porcine spinal…

Exploring the Link Between Lower Back Pain, Disc Degeneration and Intradiscal Pressure

A study of in vivo intradiscal pressure in subjects with and without lower back pain (LBP) sought to find out how disc degeneration affects intradiscal pressure, measure the loading capacity of the L4/L5 IVD segment, and determine any relationship…

The Effects of Inflammatory Mediators in IVD Pain—a Review

A review investigating the role of inflammatory mediators in the degeneration of intervertebral discs (IVD) found that in-vitro disc cells exposed to inflammatory conditions can release cytokines and other neurogenic and angiogenic factors and…

High Intensity Zone (HIZ) – Posterior Annulus

A high intensity zone should not be overlooked-especially with a symptomatic patient. This is a bright white finding on MRI, most notable on the posterior annulus. In a recent study in The Journal of Medical Investigation, researchers looked…

Discogenic Pain Model – Dynamic Disc Model

Discogenic pain is controversial--or is it? Low back pain is common, really common, and responsible for the second most common reason why people visit their doctors. And yet, it still continues to elude scientists of its specific origin. One…

Mechanical Disc Strain Causes Inflammation

In a recent paper published in Arthritis and Research Therapy, researchers showed how mechanical disc strain causes inflammation. Mechanical factors have always been a suspected cause of spinal problems. These factors include moving the spine…
