The Hybrid Split Dynamic Disc Model was designed with the busy doctor in mind, allowing a side by side comparison of normal and degeneration. With a midsagittal cut hybrid split lumbar vertebra and disc, dynamically demonstrate many comparative features to allow patients to understand quickly and efficiently. This is a marrying of the Professional LxH Lumbar Model and the Stenosis/Degenerative Lumbar Model with the added features of degenerative innervation. Optional cauda equina with or without rootlets.

Details included on the Stenosis Degenerative Half:

Reduced disc height (20 degrees annular fibre angle)
Thicker annular wall
View lateral window into disc innervation
Innervation deep into the disc as far reaching as the nucleus
Multiple annular inner fissures
Kidney shaped posterior inner annulus
Disc bulge encroaching into lateral recess
Red facet arthropathy without blue hyaline…palpable difference to contralateral smooth facets
Vertebral body height loss with osteophytes
Simulated calcified endplate pores
Endplate fracture
Narrowed spinal canal
FULLY DYNAMIC WITHOUT HERNIATION

Details included on the Professional LxH Half:

Good disc height
View lateral window to show outer innervated annulus
30 degree anular fibres from the horizontal and an additional exposed layer showing -30 degrees in the next inner layer
Annular innervation (minimal penetration into nucleus)
One radial annular fissure to match up with the herniating nucleus under load
Cancellous bone
Polished facets and blue painted hyaline
FULLY DYNAMIC HERNIATING NUCLEUS


Both halves of model include a nucleus with randomly scattered reflective particles to clearly show nuclear movement under differing vector loads.



NOTE: Each model is individually crafted and small variations may exist between models and may not be exactly as shown…but it will be pretty darn close!
