The Best Way To “Show” Decompression. Life-Like Lumbar Disc Model
New features include:
circumferential (diffuse) disc bulge
superimposed disc protrusion
limacon shaped annulus
peripherally exposed calcified endplate
elastomeric white articular cartilage
subchondrial bone exposed with hyaline fibrillation
bone coloured L5
white superior endplate matching the colour of the articular cartilage
New cauda equina
The features that remain (from the previous model):
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
randomly scattered and embedded black nuclear structures to easily show nuclear shifting dynamics through the L4 view lens
L5 superior endplate pores (black)
L5 superior endplate lesion (red)
vasculature in L4 vertebral body (red)
facet subchondrial vascularization (red)
facet tropism (L5 inferior)
Detailed cauda equina includes: sensory and motor divisions, dorsal root ganglion, recurrent meningeal, gray rami communicans, 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.
