Degenerative Spondylolisthesis
The Degenerative Spondylolisthesis Model (L4-5) by Dynamic Disc Designs is an educational tool designed to demonstrate a grade 1 anterior spondylolisthesis with an intact pars. It highlights the degenerative nature of the facets, which is the most common form of spondylolisthesis. The model features a stiff yet dynamic one-part disc that allows motion at the L4-5 level, illustrating how spinal canals narrow in extension and open in flexion. This is particularly useful for explaining symptoms associated with spinal stenosis, such as why sitting (spinal flexion) may relieve symptoms and walking (spinal extension) may exacerbate them.
The model includes optional features such as a shortened cauda equina, arthritic facet, thickened ligamentum flavum, and a step defect. It also demonstrates further listhesis under load, providing a comprehensive view of the condition.
