Lumbar single level model to show the motion at one level. The intervertebral discs are visceoelastic and show be represented this way in education modeling. At Dynamic Disc Designs we have worked hard to show the realistic anatomy of a lumbar motion segment so focused education can take place. Whether it is disc bulge, disc protrusion, or disc extrusion is something that needs to be explained, our handcrafted models will hold up to daily use for the doctors that are serious about educating their patients.
