“This model with the bulging nucleus is exactly what we see in real discs – it's brilliant. It is a perfect teaching tool”

Stuart M. McGill Ph.D. Professor of Spine Biomechanics, University of Waterloo

“With your models, my patient education potential has taken off to a whole new level! Best purchase I could have made”

Barry Kluner DC, Chiropractor Malaysia

ddd models are now considered the gold standard in spine modeling. Custom models are available with the option to consult with Dr. Jerome Fryer to ensure the right message is conveyed in (and out of) court.

Dynamic Disc Designs


Dynamic Disc Designs Corp. is a spine model company pioneered and developed by Jerome Fryer BSc DC.  The attention to detail is unparalleled with many professional spine doctors and educators utilizing the models to help improve outcomes through higher patient education. If spine education is important to you, your company, or your institution, explore the most reputable spine modeling company on the market today. Our focus is on human spine models and unmatched in quality and anatomical detail — being touted as revolutionary for spine educators world-wide. Dynamic Disc Designs (ddd) handcrafts dynamic anatomy including features of a herniating nucleus under manual compression. With an elastomeric two-part intervertebral disc, now many more important anatomical and biomechanical features can be explained to help patients understand pain generators. These hands-on 3d models enable spine professionals (chiropractors, spine surgeons, osteopaths, physiotherapists) to quickly and easily show the complexities of spine movement to help improve education and the bottom line–clinical outcomes.


Spine Models

Anatomical models, in the past, have been static and not representative of the research. Dr. Jerome Fryer (founder and chief innovation officer at Dynamic Disc Designs Corp) believed it was time to develop a modeling company that provides a dynamic look into pain generators to help improve outcomes through education. ddd models are rooted from strong research and gives the spine professional confidence in using the models for effective patient education. Offered anatomical details include: innervation to the intervertebral disc, innervation to the facet joints, neoinnervation to inner annulus fibrosus, dynamic disc bulging, delamination to the annulus, dynamic disc height loss, disc herniation under load, flexion load and nuclear shifting, degenerative disc height loss, stenosis models, subluxation models, audible release models, lumbar models, cervical models, epidural puncture models and much more. Clinically, for example, enabling patients a closer look into the nucleus pulposus shifting can aid in the prevention of a flexion intolerant back to understand the movements that stress the posterior annulus.


“This is the best lumbar spine model I have seen. I am proud to possess one. It will be of great value when explaining to my patients as well as in my research using Upright MRI ” Francis W. Smith MD Clinical Professor of Radiology Positional MRI Centre Woodend Hospital Aberdeen, Scotland
