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.
