New for 2019 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. Spondylolisthesis induced by manual pressure. Details include our trademarked dynamic 2-part disc with 6 degrees of freedom and a L4 endplate lens, to view a radial and circumferential fissures on the top of the annulus fibrosus. The nucleus pulposus is clear 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 details of a radial fissure can be seen through the clear L4 vertebra as in our Academic LxH Dynamic Disc Model. This model can be helpful for patient education if rest is clinically warranted or in the discussion of listhesis. Show how the spinal canal is usually spared for spacing with this type of spondylolisthesis.
