Professional LxH Dynamic Disc Model

Features include:

• new cauda equina with optional rootlets (blue) (2020 update)
• circumferential (diffuse) disc bulge
• superimposed disc protrusion
• limacon shaped annulus
• peripherally exposed calcified endplate
• elastomeric white articular cartilage
• subchondrial bone exposed with a hyaline fibrillation
• bone coloured L5
• white superior endplate matching the colour of the articular cartilage
• blue coloured intervertebral disc innervation
• Flexible and 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 the outer third of the annulus
• nerve ingrowth (neo-innervation) to the inner two-thirds of the damaged annulus to help demonstrate chronic pain
• left partial posterior-lateral radial tear matching up to the disc protrusion (contained nucleus)
• anterior circumferential tear
• transparent L4
• randomly scattered and embedded black nuclear structures to show nuclear shifting dynamics through the L4 view lens easily
• L5 superior endplate pores (black)
• L5 superior endplate lesion (red)
• vasculature in L4 vertebral body (red)
• facet subchondrial vascularization (red)
• facet tropism (L5 inferior)
