Product Description

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!

    Of all the lumbar models this hybrid is the one that patients best understand. To be able to compare “normal” with the effects of diminishing disc height on the mechanics of the spine is genius and easily understood by patients.
