Description

Delamination lumbar model. This is a Stuart McGill inspired model. Delamination to the annulus fibrosus is a common clinical finding in the generation of back pain. In this model, a circumferential (concentric) fissure is within the posterior annulus. Granulation tissue surrounds the delaminated tear with innervation demonstrating sensory pain generators from the sinuvertebral nerve. Included in this model is a dynamic nucleus with embedded particles to show the dynamic nature of nuclear movement in discussions of pain generators with movement…in particular with flexion loads. This model is also helpful in the explanation of stiffness (1, 2) and soreness in the morning hours after a period of rest and in the prevention of disc herniation.

Model includes herniation. Dynamic Disc bulging with the update 2020 can be demonstrated. Cauda equina and the rootlets option available.

Details include:

  • flexible and totally dynamic disc. This is achieved through a realistic 2-part intervertebral disc with 6 degrees of freedom.
  • circumferential tear with granulation tissue
  • intervertebral disc innervation to outer third of annulus to demonstrate discogenic pain
  • nerve ingrowth (neo-innervation) to granulation tissue in annulus to help demonstrate chronic pain
  • transparent L4
  • bone coloured opaque L5
  • embedded nuclear structure to demonstrate nuclear shifting dynamics (embedded structure simulated proteoglycan)
  • endplate (white)
  • endplate pores (black)
  • endplate lesion (red)
  • vasculature in L4 vertebral body (red)
  • facet hyaline cartilage (white)
  • facet subchondrial vascularization (red)
  • Detailed cauda equina (optional) with rootlets (optional)
