Cervical Spine Anatomical Model

A Cervical Spine Anatomical Model Sheds Light on a Complex System

 

The cervical spine – more commonly known as the neck – is a complex configuration of the seven vertebral bodies that make up the upper part of the spine. But you already knew that, right?

If you are a doctor or other professional who works with issues of the cervical spine, chances are you’ve studied this part of the anatomy in depth and that you know all about the particulars of C1 through C7 and understand the importance of a healthy cervical spine. Good for you!

Of course, if you’re a patient who’s having cervical spine problems, including severe neck pain, you’re probably not too adept at figuring out why it is that you’re hurting and what you can do to ease the pain. That’s why you’re going to a chiropractor, physiotherapy, massage therapist, or other professional. You hope that you’ll walk away with answers.

So, if you’re that medical professional to which people turn when they have cervical spine pain, what do YOU do to help them clearly understand what’s gone wrong inside their body? In many cases, we – as professionals – enjoy using our words to explain to our patients why they are in pain. We’ve all been there, most likely on both sides of the fence. You’ve no doubt done the explaining and have also been explained to…at least sometime during your life. But, being a medical professional, you’re at an advantage. You can largely understand what another doctor is explaining to you. Your patients may not fare as well.

But with visual aids, your verbal explanation can go a lot further. If cervical pain is your specialty, you should consider an investment in an education tool that tells the whole story through the sense of sight and touch, such as Dynamic Disc Design’s cervical spine anatomical models.

The company’s Professional CxH model, for example, provides patients (or students of cervical spine pathologies) a close look at the inner workings of this part of the body’s nervous system. It includes a two-part intervertebral disc with six degrees of natural motion with a red post-lateral nuclear migration upon manual compression, posterior longitudinal ligament (PLL), anterior longitudinal ligament (ALL) and periosteal fascia (POL) (adjacent to uncovertebral joint). Doctors find this model extremely helpful for discussions involving pain related to the uncovertebral joint, IVF narrowing, and dynamic disc changes related to the facets. A ligamentum flavum is available as an extra feature.

While the Professional CxH model is the most comprehensive 3D cervical spine anatomical model offered, Dynamic Disc Design’s also produces a cervical spinal stenosis model, an upper cervical model, a hypermobility cervical model, and a multi-level, multi-coloured cervical model. There’s also the one-of-a-kind Cervical Prox1.

Offering clients a look at a cervical spine anatomical model has a few distinct advantages. First of all, because many individuals learn best from visuals, they walk away with a clearer understanding of their problems. In addition, patients who truly believe they’ve “connected” with their doctor and believe that their doctor “understands them” are the ones that return. In short, you’ve helped them develop confidence in your knowledge and your abilities. That sort of connection makes for life-long patients.

Dynamic Disc Designs’ cervical spine anatomical models are affordable, even for those just starting their practice, and because they are well-made with careful attention to detail, they are not only super-accurate but also long-lasting, making them a sound investment for any doctor who treats the cervical spine. Check out the available selection and choose one or more that fit your needs.

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 of day or night. A common complaint is stiffness in the morning or after a period of rest while lying down. Early morning stiffness has been thought to be a telltale sign of a degenerative disc. The behaviour of annular fissuring and wedging with the combination of early morning accelerated disc height loss, results in the symptoms of stiffness. To see this you can view the movement of the nucleus in any of our clear bones models.

Patients also complain that back and/or leg symptoms come on later on in the day and into the evening. The diurnal disc can lose up to 20% of its hydraulic height. We do know also, that with height loss, the facets slide and shingle into one another.

You can see well within the contents of the video above, how the disc height can cause a shingling effect of the facets. Facets are pain generators, as can be seen in our medial branch model.

Generally, and I do mean generally, symptoms that come on later in the day are more likely to be from the facet joints. This can be further supported if the patient explains that sitting relieves their symptoms. A further possibility would be stenosis if the patient explains that sitting relieves leg symptoms. We know that sitting both opens the facet joints and the spinal canal of the lumbar spine.  This can be seen in many of of our spine models including our Stenosis Degenerated Model.
