Spondylolytic Spondylolisthesis Dynamic Disc Model
This spondylolytic spondylolisthesis model has been designed with the spine clinician in mind who wants to educate their patients about spondylolisthesis due to a pars defect. Details include our trademarked dynamic 2-part disc with 6 degrees of freedom and an L4 endplate lens to view radial and circumferential fissures on the top of the annulus fibrosus. The nucleus pulposus is transparent with the embedded nuclear structures showing dynamic motion under differing compressive loads, including protrusion and extrusion with a diffuse disc bulging disc. Other features include the ligamentum flavum, herniation upon manual compression, red subchondrial structure with an elastomeric white simulated hyaline cartilage, cartilage injury, simulated endplate fracture, and endplate pores. Annular radial fissure details are visualized through the transparent L4 vertebra — as in our Academic LxH Dynamic Disc Model. This model can be helpful for patient education if rest is clinically warranted in the young athlete or the discussion of listhesis. Show how the spinal canal is spared for spacing with this type of spondylolisthesis. Spondylolisthesis induced by manual pressure.
Cauda Equina available as an optional feature with the rootlets if desired.

For teaching patients and using at demonstrations when teaching it is great to have anatomical accuracy that gives me confidence in what I am saying is correct. Been using the models for years Leonard Faye DC., FRCCSS(Can)Hon., FICC
