Manufacturer's Description:  "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 spine-disc model which more closely resembles the real thing. With a markedly different annulus fibrosus and nucleus pulposus demonstrate: disc protrusion, disc extrusion, disc bulge, intervertebral foraminal (IVF) encroachment, facet imbrication, cord encroachment related to disc, and nerve root compression...the way it should be demonstrated….dynamically!  Importantly, 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 IVF and the facets. Demonstrate disc creep and sheer stress as well as nerve tension signs, nerve flossing and mechanical mechanisms of antalgia.  Help patients understand the progressive nature of disc herniations with a protruding nucleus under compressive flexion loads through a torn and inflamed posterior annulus. With an engineered see-through L4 lens, show patients a superior view of the disc and related structures. Demonstrate radial and circumferential annular tears, endplate fracture and endplate pores to open up discussions of related hydraulics and disc nutrition.  Demonstrate ranges of intervertebral motion including all coupled actions.  This LxH model does much more…"
