Degenerated Spondylolisthesis Model

A spine model with grade 1 anterior spondylolisthesis - useful for explaining spinal stenosis symptoms

Degenerated spondylolisthesis is the most common form of spondylolisthesis. This condition is known to lead to spinal stenosis and found quite commonly in the elderly. When revealed by imaging, doctors often have to explain what this means to a patient without an accurate spinal model. An example of some research published on Degenerated Spondylolisthesis, a […]

Spondylolisthesis Models

Spondylolysis Spondylolisthesis - Dynamic Disc Designs

Spondylolisthesis is simply the slippage of one vertebra on another. The medical Latin root comes from the Greek root “spondylos” and “listhesis” which means vertebra slippage. They are defined by either a slippage forward, backward or sideways. These are labeled as an anterior, posterior or lateral listhesis, respectively. There are several degrees of slippage defined by […]

Diurnal Disc and Symptoms

Diurnal Disc - Dynamic Disc Designs

Back pain can be tricky to figure out but the diurnal disc can elude to the root of the issue if doctors are paying close attention to the history and associated relieving body position. Spinal symptoms are often diurnal. In other words, patients can often explain the onset of their symptoms based on the time […]

Dynamic Degenerative Disc Model

Degenerated Disc Model - Dynamic Disc Designs

Coming this fall, a Dynamic Degenerative Disc Model with the ability to show innervation of the nucleus pulposus dynamically. Dynamic Disc Designs strives to showcase important research in a dynamic platform so spine doctors can effectively educate their patients. This new design includes many new features including: dynamic two-part disc that is easier to squeeze […]

Disc Herniations | What causes them? | Learning from Astronauts

Disc Herniations

Goal of the Study? In this primary research article 1, the authors aim to figure out the cause of disc herniations by learning from the experiences of astronauts.   Why are they doing this study? When returning from space flight, astronauts experience a higher incidence of disc herniations when compared to the general population. The […]

Anatomical Spine Models – Attention to detail

Anatomical Spine Modes - Dynamic Disc Designs

Dynamic Disc Designs looks to provide the provider the best anatomical spine models. Some of the attention to detail includes a dynamic disc to allow complete visualization of the intervertebral disc. The foundation in the development of any of the lumbar or cervical models begins with Dr. Jerome Fryer carefully understanding the anatomy involved in pain generation. […]

Spinal Nerves – sensory/motor divisions modeled

Spinal Nerves - Sensory and Motor Divisions

Spinal nerves exit (and enter) through the intervertebral foramen. The spinal nerve consist of two main divisions (anterior/motor and posterior/sensory). A patient’s symptoms are often related to whether the anterior division or posterior division is compromised.  This can occur as a soft compromise (like a disc bulge, or herniation) or by an inflammatory process (like […]

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 […]
