Spinal Cord and its contents below

Nerve Lumbar Model

Our cauda equina and contents | modelling updating our model anatomy Spinal Cord and Endings The spinal cord is a delicate structure. It is protected by the neural arch of the vertebrae and also by the intervertebral discs anteriorly and the ligamentum flava posteriorly. Below the thoracic region, the spinal cord comes to an end, […]

Disc Herniation Model – Dynamic Nuclear Movement

Disc Herniation Model - Dynamic Disc Model

Disc herniation is a common term used to describe the disruption of the intervertebral disc. A disc herniation model is helpful is the explanation of how the nucleus pushes out radially through the outer walls of the disc. Recently, lumbar disc terminology has been updated as there has been some confusion in the nomenclature in […]

Chiropractic Models – Helping to Improve Outcomes

chiropractic models

Chiropractic Models help with outcomes. Doctors of chiropractic use chiropractic models to educate patients on the anatomy in question. Often patients just want to know where and why it hurts and how can the chiropractor relieve the symptoms. Pain can come from a few common spots in the spine. The lumbar or cervical discs, themselves, […]

Lumbar Disc Assessment – Research Update

Lumbar Disc Research - Intervertebral Disc

Lumbar Disc Assessment of Bedrest using MRI Lumbar disc assessment of glycoaminoglycan content by MRI was investigated using gadolinium to look at the changes that took place after 21 days of bedrest. This research published in PLOS One investigated the effects of recumbancy on the lumbar discs to get a better understanding of whether the discs […]

Low rate loading of intervertebral disc disease

low rate loading of intervertebral disc

Low rate loading of intervertebral disc disease (IVD) demonstrated enhanced net transport into the intervertebral disc In Vivo in a recent study published in The Spine Journal. These authors looked low rate loading (0.5hz )  of rabbit subjects and measured the uptake of gadodiamide. What they found was low rate loading improved lumbar disc clearance from […]

Back Pain with Sitting

sitting and back pain

Many people experience back pain with sitting. In a recent study published in the American Academy of Physical Medicine and Rehabilitation titled : Changes in Lumbar Disk Morphology Associated With Prolonged Sitting Assessed by MagneticResonance Imaging  these authors used mid sagittal lumbar magnetic resonance imaging to evaluate continuous sitting and sitting with positional changes every 15 minutes. They […]

Disc Height Loss and Preclinical Instability

annulus angle and disc height loss

Disc height loss is the common theme in back pain. And with early disc height loss, hypermobility is related. But how are they associated to one another? Barr in 1948 (1) was the first to describe instability. His description of low back pain related to disc height and the passive stabilizers. A nice review of […]

Spine models to improve outcomes

Spine Models - Dynamic Disc Designs Corp.

Spine models have been used for decades, if not centuries, to convey spinal problems. Models on the market have been static and not dynamic. Simply, pain is most often dynamic in nature so it is hard to understand why some professionals still use models that do not move to educate their patients. The spine is […]

Intradiscal pressure and height

Disc Height Model

Intradiscal pressure depends on the understanding disc height loss and its relationship to load. In a recent publication titled: Intradiscal pressure depends on recent loading and correlates with disc height and compressive stiffness, these authors tackled an important topic to help reveal the deformation an intervertebral disc will experience when subjected to prolonged and oscillatory […]
