This new lumbar vertebral disc model is what educators have been craving. With deep desires to communicate to patients quickly and effectively in clinical situations, I decided that it was time to develop a disc model that is dynamic in every way; so patients can understand the cause and source of their pain. After many painstaking hours of work with real tissue, a product was developed that effectively speeds-up and facilitates doctor-patient communication related to low back pain so people get it.

ddd introduces the first dynamic two-part intervertebral disc spinal model which more closely resembles the real thing. With a markedly different annulus fibrosis and nucleus pulposus demonstrate: disc herniation, disc bulge, intervertebral foraminal (IVF) encroachment, facet imbrication, central stenosis related to disc, and nerve root compression...the way it should be demonstrated. Also use this model to help patients understand spinal load intolerances to facilitate healing through educational rehabilitation. Demonstrate stability and instability concepts in a dynamic way. Demonstrate compressive load resistance, with careful R&D to provide an in vivo resistance feel upon compression. Demonstrate disc height loss and its relationship to the intervertebral foramen. Demonstrate creep. Demonstrate sheer disc stress, nerve tension signs, nerve flossing, antalgia, and nuclear migration through a torn annulus. Demonstrate endplate pores, endplate fracture and calcification with its relationship to endplate perfusion. Demonstrate flexion, extension, lateral flexion and coupled motions.
