Intradiscal Pressures in Sheep

intradiscal pressures

Animal models to understand the human lumbar intervertebral disc. intradiscal pressures in sheep Wilke et al. looked at intradiscal pressures during daily activities in sheep-one of the most comparable animal models to humans. Back pain is most linked to intervertebral disc degeneration, including proteoglycan loss with accompanying water loss and disc height loss. But to […]

Audible Articular Release Model

Audible articular release

Audible articular release sounds are very common with spinal manipulation. There are still many people afraid of the sound and prevent them from trying spinal manipulation as a treatment for back or neck pain. To improve the explanation of this common procedure, Dr. Jerome Fryer, chief innovations officer at Dynamic Disc Designs Corp., has developed an […]

Audible Noises and Synovial Joints

Synovial Joints, Synovial Fold

The classic “pop” or “snap” or audible noises associated with a synovial joint distraction is a curious sound. There seems to be a generalized consensus that the structure responsible for the noise is a gas bubble. For a review, you can read here and find out that we don’t really know where the sound is […]

Types of Lumbar Models

Modeling by Dynamic Disc Designs Corp.

Our lumbar models will help you educate your patients, allow you to accurately articulate what the patient’s body is experiencing, and explain best practices to alleviate their pain. Lower back pain is a common complaint among patients – 8 in 10 people experience back pain at some point in their life. Recognizing that such pain […]

Dynamic Cervical Spine

Central herniation under load

Many clinical symptoms are a result of a dynamic cervical spine. In a recent article titled : Dynamic Changes of the Ligamentum Flavum in the Cervical Spine Assessed with Kinetic Magnetic Resonance Imaging Authors looked at quantifying ligamentum flavum thickening with dynamic motion using kinetic MRI. They found the ligamentum flavum increases thickness with extension […]

Clinical Spinal Complaints are often Diurnal

Disc Bulge Model

Many clinical spinal complaints are correlated to diurnal (which means the day-night cycle) influences. It is well known that the intervertebral discs lose and regain hydraulic fluid over the course of this cycle. Specifically, we know water compresses out of the discs and lying down will re-imbibe the loss. Research has shown approximately 16% of […]

Types of Cervical Models

Cervical Models

When educating on the intricate mechanisms of cervical vertebrae and intervertebral disc, visual demonstration is often proven to be the most effective technique. At Dynamic Disc Designs, we are committed to providing the best spine models in the world to assist in this educational process. To that end, our line of cervical models are realistic […]

Mechanical Upregulation

Annulus Fissures

Mechanical upregulation is a popular topic. We know that intervertebral cells respond to physical stimuli. But at what mechanical frequency is the key.  Important information has been revealed in this foundational research showing how specific vibrations upregulate disc cells. Forces of varying magnitudes and durations have been used clinically in the conservative approach to spine […]

Lumbar Discogenic Pain

Lumbar Discogenic Pain Vertebra model

Lumbar Discogenic Pain pain from the disc itself Lumbar discogenic pain is common. Nikolai Bogduk, MD presents a State-of-the Art review on discogenic pain. He concludes : “Discogenic pain can occur and can be diagnosed if strict operational criteria are used….”  It is refreshing to see true, foundational research. Dynamic Disc Designs offers lumbar models […]
