A one-level dynamic degenerated cervical spinal stenosis model with significantly reduced disc height, central disc bulge, central annular fissure and respective red nuclear herniation to extrude under load. This model also includes a thickened ligamentum flavum. Demonstrate central stenosis with a central herniation under load dynamically and interactively with patients or students: actual size and exact anatomical detail. A cervical degenerated herniating spine model can take your spine education to a new level.
