The Professional LxH Dynamic Disc Model is our most popular for patient education and now considered the standard in spine modelling.
This intervertebral disc model includes:
flexible and totally dynamic herniating (or prolapse) nucleus pulposus. This is achieved through a realistic 2-part intervertebral disc with 6 degrees of freedom. Nuclear migration upon manual compression through a torn annulus fibrosus explaining pain generators under load.
right posterior-lateral radial and circumferential(concentric) fissure
intervertebral disc innervation to outer third of annulus to demonstrate discogenic pain
nerve ingrowth (neo-innervation) to inner two thirds of damaged annulus to help demonstrate chronic pain
left partial posterior-lateral radial tear to help demonstrate the progressive nature of disc herniation and earlier forms of degenerative disc disease
anterior circumferential tear
transparent L4
clinic white opaque L5
NEW randomly scattered and embedded nuclear structures to easily show nuclear shifting dynamics through the L4 view lens

Detailed cauda equina includes: sensory and motor divisions, dorsal root ganglion, recurrent meningeal, gray rami communicantes, posterior primary division, dura mater, arachnoid sheath, rootlets, properly placed nerve root to accurately demonstrate the most commonly affected nerve with a post-lateral herniated disc.
