Our lumbar models are identical in size and geometry to a real cadaveric specimen. With careful construction of the soft tissues including a flexible intervertebral disc including an annulus fibrosus and a nucleus puplosus,  each model is meticulously hand-crafted to provide the most accurate modeling to help the musculoskeletal practitioner to engage with patients in a convincing way.

Lumbar models have historically been static and immobile, but at Dynamic Disc Designs, we have developed flexible lumbar models to help relay essential movements to the patient related to their pain triggers. Having a patient genuinely understand their body mechanics empowers the patient and improves outcomes.

Patient-centered care must include translational strategies to help a pain sufferer understand their origins. A dynamic lumbar model helps execute efficient and accurate patient education.

Vertebral Osteophyte. Is it related to mechanics?

The patterns of vertebral osteophytosis (or the growth of bony projections from vertebrae) is a common study among researchers. The actual cause of these bony outgrowth projections has been questioned over the years, with some pointing to the…

Does Muscular Flexion–relaxation Response Change Due to Static Flexion?

A study [1. Flexion–relaxation response to static lumbar flexion in males and females] in the journal of Clinical Biomechanics shared results pointing toward the relationship between the muscular flexion-relaxation response in humans and…

What are the Risk Factors Associated with Recurrent Lumbar Disc Herniation After Discectomy?

Not many reports address whether LSTV (Lumbosacral transitional vertebrae) has a link with LDH (Lumbar disc herniation). A study [1. Risk factors for recurrent lumbar disc herniation after discectomy], in the journal International Orthopedics,…

Can Verbal Suggestions Manage Musculoskeletal Pain? A Review

How much of an impact do verbal suggestions have on managing pain? We can’t be entirely sure. There has been a lot of controversy surrounding the power of suggestion and pain management. A review [1. The influence of verbal suggestions in…

Assessing the Relationship Between Biomechanical Instability and Degenerative Changes in the Lumbar Spine in CLBP Patients

There still seems to be some controversy when it comes to addressing the relationship between biomechanical instability and the degenerative changes in the lumbar spine in CLBP (chronic lower back pain) patients. A study [1. Is L5–S1 motion…
