Lumbar Model - Hybrid Split
The Hybrid Split Lumbar Model was designed with the busy doctor in mind, allowing a side by side comparison of normal and degeneration. With a midsagittally 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 theStenosis/Degenerative Lumbar Model with the added features of degenerative innervation.
Details included on the Stenosis Degenerative Half:
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
- 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…significant contralateral comparison)
- 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
